This is a far bigger issue than not being able to create a spice simulation but using separate power pin units is fairly common for big FPGAs and uCs so I'm guessing users are aware of the potential pitfalls. > > Fixing that should be in V6 version (as separate symbol power pins unit is a > good idea), but it > cannot be made in V5.x > I'm indifferent about the separate power pin unit for logic ICs and op-amps. They make more sense to me for larger ICs. In the mean time we should probably find a solution for spice users since we broke the logic and op-amp symbols. The easiest solution would be to provide the old logic and amplifier libraries. I don't want this to hold up the v5 release but we should consider creating separate spice logic and op-amp symbol libraries for 5.1. _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
