gEDA-user: mixed 5.0/3.3/1.8 V designs?

2002-07-11 Thread mcmahill
Given that the power supply connections for many of the logic symbols in the gaf library are implicit (not shown, considered evil by some) whats the way to mix different digital supply voltages in the same design and be fairly certain of not having the wrong ones connected? Also, is it possible

Personally, I never use logic symbols (for board design) that don't have explicit power and ground connections. There are three reasons forcing this approach: (1) mixed signal (analog and digital) _have_ to be segmented (2) any non-trivial digital design will use multiple voltages (3) any high
