KiCad 8: Working with Circuit Simulations!

I thought I had a neat workflow to solve the problem of not being able to simulate the entire project:

The idea was to use the parent (root) sheet for everything non-simulateable, and have child sheets that would be simulated in isolation if desired. No errors/warnings for the entire project when running ERC:

However, closing the project, and opening just one sheet in isolation (i.e. by right-clicking on the file (technically a copy of the file, since I didn't want to corrupt the original) and selecting Open With->KiCad Schematic Editor 8.0) causes this weird error when running the ERC:

And that weird ERC error of "wires not connected to anything" of course means that the simulation result will be very incorrect.

I don't know what's causing it. Maybe it's simply unsupported to try opening sheets outside of a project and expecting things to work.

I've raised a bug report.

Very cool capability.

So much has changed since I learned electronics.

Brilliant. Nice work. I'm still at the tutorial level, but this is VERY cool.

Thanks for the write-up!I think you just gave me something to play with this weekend [emoticon:6d505171faa4497c85c5ca27290c555d]

Circuit simulation is a topic I've always been fascinated by, but it's normally been a separate process than the PCB design for me, and thus something I've not done a lot of. Love to see this integrated in KiCad!
