@User, back annotation works great! Thanks for the tutorial. I am however running into issues when trying to annotate device operating points with the sky130 devices, and I think it's got something to do with the fact that the names are convoluted e.g. "@m.xm4.msky130_fd_pr__pfet_g5v0d10v5[gm]", rather than just "@m4[gm]". Do you have any suggestions about that?
