np, i can even give you schematic diagrams etc if you need, i have to document all this some time anyway. I even have layout diagrams if you want, but you probably just need gate sizing figures.

Well, later might need yr full name to be in my project report  Hope my lecturer accept my proposal, will inform u a.s.a.p.  btw, do u know any books have this kind of figures? Maybe i can js get from there and save your hassles.

During my training, I came across several soldering techniques like wave soldering, manual soldering and etc. These terms appear in the datasheets.
Any sites to go to have a brief idea on what are them?

My figures are not from books, they are from my own custom made gates  And don't worry about it, because i have to make presentations on my project etc so i need to document all this anyway.

My conventional full CMOS 1 bit full adder/subtractor/AND layout, i'm proud of how compact it is since i slaved over it for many many hours  32 transistors total. 3 metal layers. blue is metal1, pink is metal2, dashes of bright green is metal3 all crammed in about 10*10 microns. Using TSMC 0.18 micron design rules.  Those people who think computer engineering is all science don't know shit. This is art in its truest form

David83, got try google-ing? I always find plenty of info there. ikanayam, that's the 1st time i see this diagram,hahaha. Well, engineering is the combination of science and art. Without creative mind we can't even come out a simple design. K7 and K8 architecture is an art man, we are going to see another masterpiece - Conroe next year

Manual soldering is just soldering done manually either you are using a soldering iron, double soldering irons or even a blower. Wave soldering, http://www.tkb-4u.com/articles/soldering/p...m/procparam.phpSoldering is basically attempting to connect parts to boards or other parts. Each technique differs to the process. So it is not always the name of the soldering or the method but more of the process it is supposed to go through such as when soldering components through SMT machines or down back to the manual soldering. Also different techniques are done for different components such as discrete, chip, ICs, components that come in different packages (tape, tray, etc..).

ikanayam, haha that is art? LOL. If only they hung pictures like that in the Lourve, then I could have related better rather than the new abstract and modern art pictures. I've seen the drawings done by my PWB specialist in my company and when the final 6 layer board is completed, now that is true art  Its so complicated that it blows me away haha

As some people like to see the architecture as an art, to me personally I think the IC itself and the fabrication techniques are a work of art. Since coming from a solid state major in uni, I think the whole atomic physics of ICs are itself brilliant and mind boggling!

Have to build a 20k transistor chip next semester for my class, have any ideas about what it shoud do? There's still plenty of time but i like to plan in advance so i can think about it over the winter. What custom functionality would be marketable today?

It will be crap easy to layout since it's just the same thing over and over. I don't think we'll even be allowed to make something that basic  The guys who won last year made the digital portion of an RFID tag with some fancy 128bit encryption and all that.

Viterbi Decoder Turbo Decoder Booth Multiplier Carry Enhanced Multiplier(don't think u can google it) DRAM(i think this is pretty easy, just the controller part might be otherwise)

By what will you be judged by?
A RF chip will be a good challenge, it's not going to be easy to design a on chip antenna, your layout must be extremely good to reduce cross coupling, images, and still have a working antenna; (more so if you want a nice layout without leaving a huge blank space for the antenna)
Plus since the last winner was somebody who did the digital portion, why don't you do the analog portion... no chance of using synthesis tools here.... and i am sure that your lecturers will put their hats off to you if you manage to pull this off
(this is going to do wonders if you plan to apply into a semicon company in the future)

Nah, i'm a digital guy, i'm not into analog stuff. And we are not allowed to use synthesis tools anyway, it's all full custom layout. Well i still have 2 months more to think about what i want to do, and i want to win, so i'll really have to think it through.
