Upstream Sky130 simulation support classes
For the simulation of the bandgap for the analog/mixed-signal library project some support classes and code have been done to do things like Ids vss Vgs curves etc. (see https://gitlab.com/Chips4Makers/c4m-pdk-sky130/-/blob/blog20221003/c4m/pdk/sky130/_simulation.py). Some of this code could be upstreamed as these are common simulation needs.
Current thinking is to move it into pdkmaster.io.spice
.
