What do you use, Stupid Technology Subforum?
I'm curious, because it seems like something there would be a ton of software for both freeware and otherwise, but I can't really find that much out there. Most of what I've run into either costs crazy money and is of the professional design full fabrication-process variety, far too complex, or just plain crap.
All I need it something that will let me draw good, clean, simple SSI/MSI diagrams without too much fuss like so
and maybe also generate truth tables and the like.
I need to illustrate a whole crapload of circuits in the next couple days for a computer architecture final project, and I'd rather not draw it all by hand or stumble through Microsoft Word's clumsy drawing tools, when there's almost certainly something way easier and more flexible out there.
So, STS, is there anything out there you can recommend?
U7A should be a 3 input AND gate and use clean outputs from the flipflops. By ANDing the result of the AND, you have a larger propagation delay.

http://www.inkscape.org/ for a FOSS, illustrator for commercial. you will have to make or find your own symbol libraries for and/or gates, etc..
Hmmm... you don't understand -- I have Illustrator. I have plenty of drawing tools, in fact; Photoshop, Fireworks, Inkscape, etc. etc. etc.
The problem is that if you draw it in illustrator, inkscape, word, etc. etc. etc. it's still just a drawing. And if you want to go change the positioning of a gate, or add something in between, you have to go physically move those points. A regular piece of vector drawing software doesn't recognize these things as nodes and wires, it just sees bezier curves, and all you're drawing is vector art.
I'm looking for something that actually allows you to place down gates, place down chips, and have them be recognized as such and easily editable. Otherwise, things get really complex really fast, and you're just going to have a mess of lines and shapes that are going to be impossible to deal with.
Found this through Wikipedia, anyone familiar with it?
I think I'll try it tonight, looks pretty decent, and almost exactly what I'm looking for:

If you need something that can be used to draw a schematic AND do some digital simulation, I've used Labcenter's Proteus Lite. It doesn't have as many features of the full version (such as a full VSM suite), but the lite version should be enough to get what you want done.
