Hi, all.
How can I include a standard cell in spice netlist code of schematic?
While I make netlists in Xschem, the standard cell that I passed doesn't come up in netlist( e.g dffqnq)

Did you design yourself this standard cell? or what process are you working on?

Anyway, if you have a standard cell symbol and a spice netlist for it, descend into the symbol and add attribute:
`spice_sym_def=/path/to/spice/file/cir`
and set the symbol type to '`subcircuit`'.

Ah, I missed that property. Thanks.
Instead of adding spice_sym_def code in symbols, I added ".include code in schematic as below.

What is Linen?
