[sdiy] complex logic problem

[Tavys Ashcroft]

Hi all,

I'm working on a sequencer design that is probably going to require at
least a small microcontroller or FPGA to take care of some logic.  But
before I go that route, I want to lay out a big old truth table and
see if I can reduce my logic needs down to a realistic number of
gates.  Perhaps I can get away with using a handfull of CMOS chips.

Is there any software out there that would automate this process, or
at least assist?  I'm hoping to just fill out a giant truth table and
have software give me possible combinations of gates that would create
the result I'm looking for.  Does such a thing exist?  If not, could
somebody point me to a good primer for doing this by hand?  I've only
ever made digital logic circuits with a few gates before and this one
is getting bigger than I can visualize.

Thanks,
Tavys
