I have only recently swapped to Kicad (now 6) so am not that knowledgeable about it. I have a schematic intention I am not sure how to deal with, if at all.
Looking at it as simply as possible, there is a top level schematic (A) and two lower level schematics (sub-A, sub-B) (a hierachy), both of which are identical and are just included directly in A. I haven’t seen specifically how to create identical copies of ‘sub-schematics’ but I guess I can do it by creating one and then duplicating it (?) .
I am assuming that the benefit of identical copies would be that editing one would automatically update the other?
However, each of those sub-schematics contains two op-amps, but the (quad) op-amp to be used for both does not contain four identical swappable units, because it has a fifth one - containing power and ground. There does not appear to be a way of saying in a part that units A-D are identical and swappable but unit E is unique - or maybe there is but I do not know it (?) .
So, it seems to me that sub-A will need to contain - say - op-amp units A and B, and sub-B will need to contain units C and D.
In that case though, sub-A and sub-B are no longer identical - they explicitly contain different units.
Not sure how to get around that apart from having to accept that sub-A and sub-B are not identical sub-schematics?
People might say “well, use two dual op-amps instead”, but that isn’t really the point, I am trying to see if and how what I would like can be done in Kicad, because it has general application.
