Not in the new v5 lib. There the power unit is separated for all symbols (unless we missed some) The reason is that as far as my research shows, one can connect multiple different nets to different power pins that way. I do not think this is a good solution. Having the power pins on the first unit creates problems if the user does not intent to use the first unit. (maybe the physical pin order does not fit the intended pcb layout) Having the power pins separate (and well designed) makes it possible to either have them on a separate sheet, overlay them with any other unit or place them near the other units. (It is the most flexible way to create such circuits)I agree with you in principal but the practical side of these changes is far more subtle as demonstrated by the simulation and erc issues. The invisible power pin issue has been around for as long as I can remember (mid 80s). Oddly enough, op-amps typically have power pins shown on all units where logic gates hide the power pins on all units. I'm not sure about the logic (pun intended) behind this but it has been this way for a long time.
We will be able to fix this once the new symbol file format is implemented. The current symbol file format has no way to indicate individual unit interchangeability so there is no way for the spice netlist formatter to add the power pin unit to each interchangeable unit so the spice model pin count matches the symbol pin count. We have effectively thrown spice users under the bus which I really don't like doing. In the short term, we can recommend that they use the old logic and op-amp symbols.
My opinion is that if there is a conflict between simulation and pcb design needs, the later should get priority. (I assume pcb design is still the core feature of kicad.) If i read the bug report correctly simulation is possible if all units are included in the schematic, so this is the correct way to go in my mind.

Hidden power pins are not the way to go! The fix for this bug must come from a different side then reintroducing hidden power pins.

I didn't think about this when the changes to the symbol libraries where made but it is going to cause issues for anyone trying to create simulations. I preferred the old symbols but it's not something I feel strongly about but given that these changes caused this issue we may need to rethink this decision or provide alternative symbols for spice simulation.

I didn't see any thing outstanding but I may have missed something while I was on vacation. I'm going to create a 5.0.0 milestone for the last few remaining bugs and shoot for a 7/20 tag date unless there are any more critical bugs lurking about. I will also create 5.0 and 5.1 branches. If I tag on 7/20, I would like to make the release announcement on 7/27. Does anyone see any issues with these dates How do stand with our installers? I saw the macos installer was making some nice progress. Are the doc devs, library devs, and translators (except for the recent minor string changes) ready? Is there anything else I'm missing? I really would like to make these dates. I have an Olimex TERES laptop kit that I've been dying to play around with but I know once I start on that, everything else will get pushed to the back burner so I'm not going to start until version 5 is released. :) Cheers, Wayne _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp_______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp_______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp_______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp_______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@xxxxxxxxxxxxxxxxxxx Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
