Schematic tool for analog design #328

Open engrvip opened 3 years ago

engrvip commented 3 years ago

Which tool is supported with sky130 pdk right now for creating analog schematic and running simulation using which SPICE engine ? Can xschem or xcircuit be used right now ?

RTimothyEdwards commented 3 years ago

xschem is well supported. For xcircuit, I made some cell libraries but ended up on the problem of how to enforce limits on the parameterized values, which needs some coding work, and I have not gone back to that yet. Xcircuit can be used, though, just doesn't enforce parameter limits (but I'm not sure xschem does, either).

Please share the steps or some reference on how can required schematic editor and simulator can be installed for initiating with analog design using sky130 pdk.
