@Stefan Schippers Is there a way to import spice netlist to xschem?
t
Three words: "Automatic schematic generation". This is a difficult problem---about the same level of complexity as place and route. Since automatic schematic generation doesn't produce actual layout, developing software to do it is less critical, and so the software never gets written. . .

@Tim Edwards Do commercial tools like Virtuoso have such functionality?
t
Yes. They have billions of dollars to spend on developing less-than-critical software.

As always thanks a million for such invaluable info. 🙏

I realize that the above comment is actually a strong argument for why commercial EDA should be charging lots of money for their software. . .

Thanks a lot @Mitch Bailey. I’ll check that out.

@Rita in many cases you can just import a netlist of a subcircuit block into xschem as plain spice text, just keep the symbol with I/O pins. The subcircuit is described by a netlist instead of a schematic circuit. By the way this allows to import extracted blocks with all parasitics.
