@User I am just now playing with XSchem... great tool! I am very impressed. But I have a question about xschem_sky130... how can I use the logic gate symbols you have provided to map to actual spice models of a gate in the pdk std cell libraries? Can I override the subcircuit statement the symbols generate? Or would I wrap the pdk spice subcircuit in another subcircuit that matches the name of the symbol?
