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

[mcmahill@mtl.mit.edu]

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 to make the supply pins visible through some property
or something to make it easier to addd some explicit series decoupling on
some of the logic chips?

Thanks
