Fun with Trends

I've been playing with Google Trends recently and have been running across neat things. My friend Charlie pointed out that no one cares about health during the holidays, and boy does google help prove that:



Actually, they only care about video games during the holidays:

I Miss Muay Thai

Oh how I miss participating in Muay Thai. Maybe I should start that up again. Why do I suddenly miss it? Heres why:

Weight Loss Competition: 11 down, 29 to go

I am right on schedule. The past three weeks I've been losing an average of 2lbs per week, so I'm down to -11lbs of my original weigh in. I'm pretty sure I'm beating my mom, although she hasn't been updating me on her losses.

I am finding this to be surprisingly easy, unlike any previous attempts by me to lose weight. What I have done is limited my daily caloric intake to 1700-2000Calories per day (some days are more, very few are less than 1700 and even then not by much). I try to eat a balanced diet, but I really don't care about balance just yet. The calorie restriction is enough so far. It gives me a 500-700 caloric deficit per day, which means I have a net calorie deficit of 3500-4900 per week, which is a little over a pound in fat per week. As long as you watch calories, you can eat anything you want (or so I have found). Yesterday I even had my favorite fast food: Taco Bell. But what has really helped me is frozen strawberries. One pound of frozen strawberries is about 150 calories. Plus they get me cold, which my body fights by increasing my core temp a little which should require burning some calories (every little bit counts).

Combine that with my resistance training (light weights/body weight) and I'm averaging 2lbs per week. I am feeling so much better than I was 5 weeks ago, although I have been sleeping more (my schedule permits).

Weight Loss Competition: Update 1

So I have lost 5lbs the first week of the competition. My official weigh in was 204 and I'm down to 199. I'll continue this regimen of eating ~1700-2000 calories a day and working out some. The long ass bike rides come soon. Only 35 lbs more to go. 35lbs to a rally car i keep telling myself.

One nice side effect: I feel better already.

Weight Loss Competition

I have recently entered a weight loss competition with my mom. We are both racing to 40lbs lost. Why would we do it other than any health benefits? Because we've made some wagers.

If I win the race I get a used car to turn into a rally car. This would especially help my TwoGuysRally progress.

If she wins, I have to make her a new walkway from our driveway to the front of the house. She has requested gravel bed with stone pavers and sand to act as a non hardening mortar. The tricky part about building it is that it has to go up in level so there is no step from our porch to the walkway.

I am pretty confident I can win, although it is a large amount of weight to be lost. I will weigh somewhere around 160-170. Weigh ins are tomorrow and I should update this with the official weigh in and finish weights.

A New Project

I come up with new things to do a lot, and just recently I have come up with a new thing to do. That new thing is really trying to get a rally team going. So me and my good friend Mark Ozimek got together and created TwoGuysRally.com to tell the world of Rally Racing. I sort of tried to accomplish the same thing with specialstage.blogspot.com but the addition of Mark to a blogging atmosphere has been huge on my writing frequency. He is quite passionate about Rally Racing too and we complement each other skill wise. He is a mechanical engineer and I am a Computer Engineer. We cover different topics and have different voices, but we both can write decently. So check us out, we can always use more interested readers.

Violence and Video Games: Jack Thompson

Jack Thompson, an unfortunately infamous name in the world of video games. Why is he so infamous? He blames video games for every violent attack possible. He was the lawyer who represented six of the victim's families from Columbine. He claims video games are simulators in which people practice how to kill (rehearsal is the word he uses). He contends that Seung-Hui Cho, the shooter behind the Virginia Tech massacre, practiced killing in High School by playing Counter-Strike (I also must have practiced killing by playing Counter-Strike, as I was very involved in the competitive CS world then, and I was pretty good at the game too .'. I am a good killer). Most recently he thought (on the day of the shooting with no real investigation) that Steven Kazmierczak, used video games (again Counter-Strike) to practice the massacre that unfolded on Valentine's Day of 2008 (Feb 14) at Northern Illionois University. Infact here is a video that includes most of what I've said, but out of his mouth:

Amazingly, the news reporter saw through his tirade and claimed they were out of time. Which has not been the case in the past. Jack Thompson is often referred to as a "School Shooting expert" and is usually interviewed on the day of school shootings for his opinion. News stations are desperate to fill time, and he is desperate to get his message spread. Both of them benefit from each other.

Regardless of his punditry, Jack Thompson's most famous event was when he offered $10,000 to charity if anyone/any company made a video game he proposed. His proposal was called "a modest video game proposal" as an attempt at allusion to "A Modest Proposal". The point was to make a game where you kill people at E3 (the expo) including the CEO of Take-Two: Paul Eibeler. He wanted to prove that games were "murder simulators" by making a game of his own that actually is a "murder simulator". That is confirmation bias to the EXTREME: fabrication of evidence to support your hypothesis. Luckily for us, Jack Thompson is not a man of reason, he is a man of frivolous law suits. And so he allows for dissections of his arguments and a very good dissection is done here.

Thankfully, the media and even NIFM, the National Institue on Media and the Family, have been distancing themselves from Jack Thompson. Even the Flordia BAR is considering revocation of his privilege to practice law. It's good to hear he's losing credibility, I guess that's what blatant lying and misuse of scientific research does.

Video Games and Violence: A dissection

I have been doing some research to complete my Critical Thinking course's assigned final project on the topic of Video Games and Violence. I chose this because I think a lot of fallacious arguments are proposed to make video games seem more detrimental to society than they really are (or they could be beneficial, but I would like to see some evidence first). Since I use this blog for everything I'm interested in (except rally racing) I figured I might as well use it as a "live research document".

Today I'm going to dissect the argument for a site claiming video games are causing violence and argues for stricter control of video games (something I very much do not think would help). The site is http://serendip.brynmawr.edu/exchange/node/1723.

Some background for the site: I suspect the original posting was done in June or earlier of 2005. The post date on the blog is 2008, but the comments come from (1st in June 2005). Also because of the age of the original post the source links do not work and should be updated (at least there were attempts at sources and are used throughout the article, although I haven't verified if they're real).

Let's get on with the dissection:

There is a huge hype surrounding the launch of every new game system - Game Cube, XBox, and Sony Playstation 2 being just few of the latest. Affecting children age 4 all the way to 45 year-old adults, these video games have called for concern in our society regarding issues such as addiction, depression, and even aggression related to the playing of video games. A recent study of children in their early teens found that almost a third played video games daily, and that 7% played for at least 30 hours a week. (1) What is more, some of these games being played like Mortal Combat, Marvel Vs. Capcom, and Doom are very interactive in the violence of slaughtering the opponent. The video game industries even put signs like "Real-life violence" and "Violence level - not recommended for children under age of 12" on their box covers, arcade fronts, and even on the game CDs themselves.

I don't have issues with this paragraph other than the criticism of the video game industry attempting to self police (without government intervention) by warning that there is violence not recommended for children under a certain age on the box and CD.

In the modern popular game Goldeneye 007 bad guys no longer disappear in a cloud of smoke when killed. Instead they perform an elaborate maneuver when killed. For example, those shot in the neck fall to their knees and then face while clutching at their throats. Other games such as Unreal Tournament and Half-Life are gorier. In these games when characters get shot a large spray of blood covers the walls and floor near the character, and on the occasions when explosives are used, the characters burst into small but recognizable body parts. In spite of the violence, the violent video games are also the more popular games on the market. (2) When video games first came out, indeed they were addictive...

I don't quite understand what the evidence of "Inspite of the violence, the violent video games are also the more popular games on the market. (2)" argues for. However, my big problem with this is the uncorroborated statement of "When video games first came out, indeed they were addictive...". There is no source to back this point up and in all the reading I've done about the history of video gaming it wasn't ever discussed as addictive more than anything else.

however, there seems to be a strong correlation now between the violent nature of games these days and the aggressive tendencies in game players.

Again there is no evidence provided for this. If I could find the cited sources for the other cites I would read those and try and link the evidence, but they provide no corroboration. I found a website that may help their argument and it is a trusted source: the APA. Here it is. There is a correlation between violent video games and I will agree with the article if they meant "increased aggressive behavior, thoughts, and affect" by "aggressive tendencies". So score one for them...maybe.

On April 20, 1999, Eric Harris and Dylan Klebold launched an assault on Columbine High School in Littleton, Colorado, murdering 13 and wounding 23 before turning the guns on themselves. Although nothing is for certain as to why these boys did what they did, we do know that Harris and Klebold both enjoyed playing the bloody, shoot-'em-up video game Doom, a game licensed by the U.S. military to train soldiers to effectively kill.

Although sources were provided throughout the article they could not provide a source for the US Military licensing "Doom" to train soldiers. No where have I found any evidence that the US military licensed Doom. Also, from the personal experience of firing guns and playing video games (both of which were very commonly done during high school)(Someone expressed some concern as to why I was shooting guns a lot in highschool, the answer: I was on my high school's Rifle Team for all four years I was there. Also I played video games daily.) Doom would not translate to learning how to effectively kill. Also the example of using Columbine is a very commonly used example and is misleadingly vivid.

The Simon Wiesenthal Center, which tracks Internet hate groups, found in its archives a copy of Harris' web site with a version of Doom. He had customized it so that there were two shooters, each with extra weapons and unlimited ammunition, and the other people in the game could not fight back. For a class project, Harris and Klebold made a videotape that was similar to their customized version of Doom. In the video, Harris and Klebold were dressed in trench coats, carried guns, and killed school athletes. They acted out their videotaped performance in real life less than a year later... (3)

The bolded section has turned out to be a hoax. They never created a columbine like level. Snopes has a good article going into it. Also unfortunately source 3 is not well described. I assume its an APA article, but since i cannot determine what it was or what it was called I'll ignore it as evidence. Also what is the sourcing of, that they "acted out their videotaped performance in real life" or that they killed people in Columbine?

Everyone deals with stress and frustrations differently. However when action is taken upon the frustration and stress, and the action is taken out in anger and aggression, the results may be very harmful to both the aggressor and the person being aggressed against, mentally, emotionally, and even physically. Aggression is action, i.e. attacking someone or a group with an intent to harm someone. It can be a verbal attack--insults, threats, sarcasm, or attributing nasty motives to them--or a physical punishment or restriction. Direct behavioral signs include being overly critical, fault finding, name-calling, accusing someone of having immoral or despicable traits or motives, nagging, whining, sarcasm, prejudice, and/or flashes of temper. (4) The crime and abuse rate in the United States has soared in the past decade. More and more children suffer from and are being treated for anger management than ever before. Now, one can't help but to wonder if these violent video games are even playing a slight part in the current statistics. I believe they do.

Again, I'm glad they're using sources but they're using all the wrong sources in the wrong places. Something less controversial such as how one can detect aggressive behavior is sourced but not a more controversial crime/abuse rate in the US soaring. All I care about when it comes to crime rate in relation to violence and video games are the violent crimes. I usually live in Virginia so that is the first state I checked for stats on. HERE. Violent crimes peaked in VA in 1993 (well before this post was written, as it was well before the Columbine Shooting) and then stayed about the same in total numbers. This all while population was increasing indicates that violent crime rates were not soaring. However, Pennsylvania, where Bryn Mawr college is located and probably the author of this article at the time of writing, has a much higher violent crime rate than Virginia. PA's violent crime totals peaked in 1996 and have stayed pretty steady around those times if not dropping. National totals confirm the same trend with a peak violent crime rate in 1991. During the decade this article was written violent crime was not soaring, infact it was down. So if you believe the evidence the Department of Justice has you should also believe this argument (whatever it is for) is a fallacious appeal to fear with incorrect facts.

Calvert and Tan (5) compared the effects of playing versus observing violent video games on young adults' arousal levels, hostile feelings, and aggressive thoughts. Results indicated that college students who had played a violent virtual reality game had a higher heart rate, reported more dizziness and nausea, and exhibited more aggressive thoughts in a posttest than those who had played a nonviolent game do.

I found source #5 through Google Docs and hopefully the link works (HERE). The author was correct in reporting the results of the study...initially. They did not study a non-violent video game specifically so they could not have concluded what the author suggests (increased arousal, dizziness and nausea, and aggressive thoughts as compared to a nonviolent video game). So a comparison linking violence to increased arousal and aggression is unfounded, when it could be more simply explained with a link to competitiveness. The study used provided a nice comparison of Darts to video games that help support this simpler explanation: "Although video game play is associated with increased hostility, the effect is smaller than that produced by television or darts (Favaro, 1983)".

A study by Irwin and Gross (6) sought to identify effects of playing an "aggressive" versus "nonaggressive" video game on second-grade boys identified as impulsive or reflective. Boys who had played the aggressive game, compared to those who had played the nonaggressive game, displayed more verbal and physical aggression to inanimate objects and playmates during a subsequent free play session. Moreover, these differences were not related to the boys' impulsive or reflective traits. Thirdly, Kirsh (7) also investigated the effects of playing a violent versus a nonviolent video game. After playing these games, third- and fourth-graders were asked questions about a hypothetical story. On three of six questions, the children who had played the violent game responded more negatively about the harmful actions of a story character than did the other children. These results suggest that playing violent video games may make children more likely to attribute hostile intentions to others.

This is the best section yet. I do not disagree with it. Just keep in mind, its about children and not related to adults at all.

In another study by Karen E. Dill, Ph.D. & Craig A. Anderson, Ph.D., violent video games were considered to be more harmful in increasing aggression than violent movies or television shows due to their interactive and engrossing nature. (8) The two studies showed that aggressive young men were especially vulnerable to violent games and that even brief exposure to violent games can temporarily increase aggressive behavior in all types of participants.
The first study was conducted with 227 college students with aggressive behavior records in the past and who completed a measure of trait aggressiveness. They were also reported to have habits of playing video games. It was found that students, who reported playing more violent video games in junior and high school, engaged in more aggressive behavior. In addition, the time spent playing video games in the past were associated with lower academic grades in college, which is a source of frustration for many students, a potential cause for anger and aggression as discussed in the previous paragraph.

Again, I don't really have any problems with this, except I am not well read on the current studies (these are from 2000) and I guarantee there are more studies. This is the first big piece of evidence the author offers.

In the second study, 210 college students were allowed to play Wolfenstein 3D, an extremely violent game, or Myst, a nonviolent game. After a short time, it was found that the students who played the violent game punished an opponent for a longer period of time compared to the students who played the non violent game. Dr. Anderson concluded by saying, "Violent video games provide a forum for learning and practicing aggressive solutions to conflict situations. It the short run, playing a violent video game appears to affect aggression by priming aggressive thoughts." Despite the fact that this study was for a short term effect, longer term effects are likely to be possible as the player learns and practices new aggression-related scripts that can become more and more accessible for the real-life conflict that may arise. (9)

The citing is incorrect, as these statements were lifted from source 8. Longer term effects were not yet studied at this point. This is a great expansion on the short term priming effect, although it could just be priming at work (if you give someone a list of words that make them think of old people, they'll move a little slower after reading the list) and no more than that. That's what the more current studies are for. Either way, maybe my inital idea of violent video games being not bad for you is wrong...we'll see, I still need more convincing.

The U.S. Surgeon General C. Everett Koop once claimed that arcade and home video games are among the top three causes of family.

I thought family was a good thing! No but joking aside I believe that Dr. Koop claimed that arcade and home video games are among the top three causes of family violence. But let's check the intertubes for confirmation. I couldn't find it, maybe I'm looking wrong, but I did find that he thought video games "had no merit and offered little in the way of anything constructive to young people". I guess I'll believe that he thought it was in the top 3 causes of family violence (that has since changed because no where in the family violence readups I've been doing have I found Video Games). However 8 years later in December of 1991, the Surgeon General of the time: David Satcher, M.D., Ph.D., led a study on violence in youth and determined that while the impact of video games on violent behavior has yet to be determined, "findings suggest that media violence has a relatively small impact on violence". The point is, I believe this to be a fallacious appeal to authority as we can find many Surgeon Generals who say very different things. Also, results that were more recently studied by the same position of authority said almost the opposite of what this article argues for.

Although there have been studies that have found video game violence to have little negative effects on their players, there are also many studies that have found a positive correlation between negative behavior, such as aggression, and video and computer game violence. Thus, in order to totally assess the effects of game violence on its users, the limiting conditions under which there are effects must be taken into account, which include age, gender, and class/level of education. (10) However, violent games do affect children, as the studies show, especially early teens, and I feel that there needs to be a stricter regulation regarding the availability of these games to young children.

"liming conditions under which there are effects must be taken into account", I completely agree with your future studies suggestion. While I will agree that games do affect children (pretty much everything does mirite?), the APA states that it is largely up to the parents of the children to make sure they understand the inappropriateness of express the violent reactions they may learn from games and why it is inappropriate. This is good, we're only partly agreeing! This means that my preliminary research into Video Games and Violence will lead me to how the media plays up the violence effects, and also how politicians do.

Thanks for putting up with my "live research document" today. I'm sure more will come later, probably as I try to explore the fallacies the news media tries to use to make video games seem evil.

Wine: Wine Tasting as Project

I have been taking a wine class (Actually 2, Wines of the World I and Wine & Food Pairing) in order to drink some neat wines and learn what really goes into wine. So far it has worked. Unfortunately in academia you're expected to do work and-or projects. So our professor had to assign us a project. It was quite an open ended project requirement, which was great. I started out with the idea of making an artsy corkscrew out of our used wine corks. But I am a procrastinator for things I'm not fervently interested in, so that was delayed too long. Although it would be a neat piece of wine art. I found out that you could host a wine tasting and it would count (just had to take some pictures and write up a little thing on it: maybe this blog post counts).

My roommates and I regularly host wine tastings, so how would this be any different? I decided to make it a blind wine tasting. Not double blind, as I am not rich and cannot afford the double blind Zinfandel glasses (my roommate has one, just one) for a large event. And I would ask my guests to write down various things about the wine: sight, smell, taste, what type of wine they think it is (varietal/blend), where it was grown, year it was grown and its price. I probably asked them to write all that stuff down to make it seem more academic and official. But there was a neat side effect, this request resulted in some pretty funny perceptions on paper about the wines. Academically speaking, that is where the interesting stuff is. New people to wine were trying to describe things that take "years of training" to describe. There are a few examples below (click for larger image), the more funny examples.

So I had to buy some wines, and knowing it would be blind I had to fool my sommelier roommate. I figured I would try and split the night evenly between whites and reds (my ideal is all red all day) so that gave me a little more guide as to what I was buying. I spent a good amount of time perusing the isles of Marketview Liquor, looking for some tricky wines and some of my favorites.

For wine A, the start of the night, I chose a light, refreshing Sauvignon Blanc made by Bogle in 2006. It is a California Sauvignon Blanc. I chose it because I have enjoyed Bogle's other varietals in the past. It was $7.99 a bottle.

For wine B I chose a trickster. A blend involving Sauvignon Blanc and Semillion. This was made by Casa Silva in 2005. A Chilean Sauvignon Blanc/Semillion blend. Chilean wines are always a great deal at $6.99 a bottle.

Wine C was time to move onto a sweet trickster. I knew I wanted to bring a German Riesling to the party but how could I fool my roommate. Also I wanted a decently late harvested Riesling, just for kicks. I chose Rienhold Haart's Spatlese from 2005. German Riesling's can get quite pricy and this ran $22.99 a bottle.

Wine D was going to be a Chardonnay. Chardonnay is one of the most popular wines and denying it some exposure at this wine tasting wasn't going to happen. But who's Chardonnay? Having just picked out two $23 bottles of Riesling I wanted a "value". So the Virgin bottle in the Chardonnay section caught my eye. I have had Virgin's (yes Richard Branson Virgin) Shiraz before and I enjoyed that (think wet leaf, mmm, or wet forest floor. delicious) so a $9.99 bottle was acceptable. (2005 Virgin Chardonnay - California)

Now I needed to move onto reds but first we needed to clear the palette. What better way to clear a palette than with bubbly. Again price mattered with the bubbly, a good French Champagne can run tons and might not be enjoyed by most of the people attending. So why wouldn't I go with the easy drinking Yellowtail Sparkling that was just released at the end of 2007. It is cheap and easy. So I picked up two bottles at $7.99 a pop.

While shopping in the bubbly section a Sparkling Shiraz caught my eye. Sparkling Shiraz I thought, what an awesome trick to pull on my roommate. Two bubblies and one was going to be deep red (or purple). There are more Sparkling Shiraz than you might think there should be. I had never heard of them before so it was definitely time to get one. So I picked up Paringa Sparkling Shiraz which was bottled in 2004 and made in the land that is so famous for its Shiraz: Australia. It was only $7.99, which was a steal for how delicious it turned out.

So now that I had whites and bubblies I needed some reds. I knew what wine E would be as It was my favorite Pinot Noir to date: Belle Valle' Pinot Noir. It was made in Willamette Valley in Oregon. Willamette is known for their Pinot Noir and Wine Spectator agrees with me on this wine: 88 points for only $10.99 a bottle (from 2006). I love this wine and will drink bottle upon bottle of it, and have.

I was getting pretty tired so I decided to pick up a Shiraz I've had for the final wine, wine F. Tim Adams' "The Benefit" Shiraz is pretty good. Also the proceeds go to a good cause, so it's a total feel good wine. Sunny Australia makes beautiful Shiraz and this was no exception. At $7.99 it is also a good deal for a Australian Shiraz from 2004.

The tasting went great. An open door during the tasting attracted even non invited people, which was great. Getting people into wine was the point and I'm pretty sure we've born some more winos here at RIT. Good wine, good people and good food make for a good time. We ended up finishing off about 19 bottles of wine, 8 of which came out late. The low alcohol, sweet italian sparkling. Saracco, which I did not have a drop of. Otherwise the most popular wine of the night was probably the Riesling. The red lovers really enjoyed the Pinot.

I would like to thank everyone who came, and especially my roommate G. Jeremy Leong for helping with the setup and my co-host Ryan Seeber for bringing some delicious cheeses and crackers. Also we do these a lot, so if you're interested don't be afraid to ask if you can come.

If you like Facebook try this link out for pictures: http://rit.facebook.com/album.php?aid=2082182&l=09e25&id=24400104

Otherwise here are some gems from the night.

Entrepreneurship: I'm doing it.

I was looking for a coop (think paid internship), which is a required course of action in the engineering programs at RIT, and I was talking to my good friend Eric Marsh (he runs metaverse solutions) .

For some background, Eric and I are both nerds and we met while I was in the 10th grade (just before 9/11/01). Since then I have frequented his house in order to play with 'toys' such as ion wind generators, monitor power supplies, all sorts of chemicals and of course computers. About a year ago I started becoming interested in starting my own company (I was working at a startup at the time, for my coop: Savant ) rather than working my life for someone else. So of course I started perusing the interweb for entrepreneur/startup related readings and stumbled onto Paul Graham's inspirational writings. That really got the ball rolling in my head about starting a company, and of course I shared this with Eric. Maybe he took this as my approval for entrepreneurs or, god help him, advice, but he dropped out of George Mason and started his current company (Metaverse Solutions). So far it has worked out for him.

Anyway back to recent times, I was looking for a coop and talking to my good friend Eric. I half-assedly offered up the possibility of starting my own company. Without skipping a beat, Eric sent me quotes and sayings all from articles I had read that boiled down to: "Now is the best time to do anything, later will be too late". He even coupled those quotes and sayings with an idea we both had discussed about 4 months before.

That is when it hit me. A surge of deep excitement, images of a future of my own company, me at the helm. I was going to do it, but I couldn't do it alone. So with some more talking I had convinced Eric to start it with me.

I'm starting a company and getting a school requirement done at the same time. I've already spent nights awake thinking about conceptual problems with our idea and how to fix them. Soon parts will be ordered so I can play with the idea in the real world. Hopefully I've got a prototype to show you ASAP, but I was just so excited that I'm finally doing it I needed to post just that.

And right now, since our idea is so fragile and still in the works I refuse to go into detail about it so publically. That will come once I've got something to show.

VLSI: Winning Competitions

In my previous post I explained an ad hoc competition I tried to start between me and my colleagues for my VLSI class. It worked and I ended up pulling a few people into the "competition". The rules were as follows: Smallest total area for the functional 32bit adder or 16bit if they were undergrad students. The implementation of the PPA adder everyone created, not the ripple carry that was also created for the project, was to be sized. The ruleset used must be the TSMC .035 ruleset.

So clearly the undergrad had an advantage (technically i was undergrad, but i was working with a grad student so our project had to be 32bits) but I was pretty sure my sizing practices would get me the win. Also I was the only one using 45 degree angles to help with routing at the time. This would later cause some neat looking designs.

Anyway, me and my partner (Nate Prosser) came up with a Brent-Kung PPA Adder that measured in at: 436x3584 Lambda.

Above you see the 32bit Brent Kung PPA Adder that I laid out (Partner figured out all the logic). Really that was a last minute attempt at design as we had switched over from a Carry Look Ahead type adder to a PPA. We decided to switch about a week before the project due date, whoops. So we designed and laid out the 32bit BK PPA in just about a week. Long nights in the lab were how it was completed. Infact I spent about 24 hours in the lab trying to lay this out (that was 2 weeks after I gave up caffeine).

A large project like this does not just happen in one go, you start small and build up with modules. In a size competition you optimize the small blocks first, and luckily I had spent the middle part of the term making really small layouts for the basic blocks I would later use. These included Inverters, Dual-Inverters, Buffers, XORs of multiple length, ANDs, ORs, 1 Bit Adders, etc... That allowed me to finish my layout in the week we had left.

This project included 3 basic modules: 2 bit XORs for the output logic, a propogate/generate generator (we could have chosen a better name I guess) and a Dot Operator.



The Dot Operator measured in at 58x105 Lambda. And good luck trying to figure out the logic from these pictures. If you're really interested ask me for the transistor level schematics.




The propogate/generate generator measured in at 68x112 Lambda. While this may look like it wastes space, the large metal rails are there for a reason. They carry the power for all those transistors (VDD on top, GND on bottom).



The 2 input XORs used on the output of the BK PPA Adder measured in at 50x87 Lambda. The set of nfets and pfets on the far left of the XOR is a dual inverter, a way I combined two inverters into one substrate that became so popular in my class everyone was using them. Really I shouldn't have been sharing my secrets for the sake of winning but I wanted it to be a decent competition. Also you get to see some of the 45 degree poly action in this XOR version.

Throughout the final layout of the project (Wednesday and Thursday night before the project was due) routing metal connections was the most frustrating part of the project. Somehow I figured out the routing and as you can see in my two example pictures it got pretty hectic. But its over and we got an A on the project regardless of my horribly thought out final implementation. I still have to get other group's numbers so I can see who won.

Also I would like to mention that our class lost its happiest member that final project week. Seth Policzer died in a house fire on the last Thursday night (Friday morning November 9th 2007) of the class. I was in the lab for 24 hours that night and I remember seeing him at about 7:30pm in the lab working with Jesse Harvey. He was leaving to eat a meal his roommates had spent all day preparing. I remember saying "see you tomorrow" to him only to fall short of that promise. I'll miss you Seth, you really were the happiest person in that class.

VLSI: Competing for the Smallest Hardware

A little context: I am a Computer Engineering student at RIT (Rochester Inst. of Tech.). I am currently (Fall '07) in a VLSI (Very Large Scale Integration) class, which teaches me how to do physical layouts of transistors to put logic on chips. However, I am a very lazy person when it comes to doing homework. Added to that I am a pretty competitive person and try and make competitions out of a lot of things. Normally I wouldn't go to the lengths I do in a class like this, but I am competing with my colleagues.

They don't acknowledge the competition I so fiercely attack. They claim they're not competing with me, as they did not know about it in the beginning. That is a cop out in my world, they're just trying to make me lose my edge.

So far, I'm winning. I judge everything by smallest area and correct behavior of the circuit. This requires some LVS (Layout vs Schematic) and basic measurements done in the program. A note: We're all using the same technology process (which is: rules and basic sizes of certain things in the layouts) so you cannot win by using a smaller process (ie 45nm vs 350nm). In this case we're using the TSMC035 process.

Lets get down to the goodies. My only screenshot at the moment. My 1 bit mirror adder, which was the smallest in the class (from a decently large survey I made).

This beaut measures in at 107x160lambda. Really it is pretty large, but it was easy to make. Any other 1 bit adder could be made much smaller than that. However, the nice thing about Mirror adders, as you can see, is the NFETs and PFETs have the same inputs (see the poly layer: red) in the same places and the widths are proportional in the same area.

More competing to come later. I'm currently working on a 32bit Carry Look Ahead adder for our final project (which will be significantly bigger than a 1 bit mirror adder).
