At the first-concept level, computer CAD really slows me down, especially if I'm considering using parts that aren't in the library. And brainstorming with multiple people works very well on a whiteboard And with a whiteboard, you can physically block people who are trying to muck with your beautiful creation. > >When I wanted to do a complete layout of this circuit, I did it on a >full sheet of newsprint.

So I'm scheduled to do a couple of lectures on basic digital design concepts, and then he'll do a couple on FPGAs and VHDL in particular. John |
