Is it just this entry that is buggy or am I doing something wrong?
Also, maybe this should be another question, but it feels pretty related:
I have two quad opamp chips TL074, for each schematic component I can choose A, B, C, D, but I don’t understand how I can manually edit the allocations into chips for optimizing the PCB layout?
Might be a mistake or they are refered this way in the datasheet. If it is really a mistake either make an issue over at the kicad library repo or better still fix it via a pull request.
Yes, it actually swapped different parts that wasn’t interchangable as you can see in the screen dump so definitely wrong there. I too looked at the data sheet and couldn’t find any naming of the two sections like A or B, The schema I’m “copying” at the moment is however calling the lower pin no section A and the higher B which kindof makes sense to me…
Follow up question which is re-iterating my last bonus question in original post
In the case where the units actually are interchangeable as in my quad op-amp (tl074), does the annotate function do some kind of try to allocate smartly since it interchanges? Or is that just to do a 1A through to 1D before adding another chip? Because Maybe I need some control over that to do the PCB design later on, right? I still don’t understand how I manually steer this allocation…?
Right click on the unit you want to change -> Edit -> Unit -> select the unit you want.
As a test i placed all four units of the 7400 symbol. Annotated it (It seems to set it up a…d) And selected unit B for the one that previously has been unit A.
After: (As you can see this tool does not exchange units. It sets the unit for the currently selected unit which will result in one unit being used multiple times.)
