Anyone know how to use the standard cells in an ngspice simulation from xschem?

@Alex Sheldon pickup a symbol, Connecticut to the signal source and load, setup the simulation an add a valid corner library

There aren't schematics for the standard cells. or model files. Do they use the Verilog?

@Alex Sheldon if you would like to simulate our std cells in analog domain we provide a full list

$PDK_ROOT/$PDK/libs.tech/xschem/sg13g2_stdcells.

You can also find all the models an libraries in`$PDK_ROOT/$PDK/libs.ref/sg13g2_stdcells.` In the last location you will find

spice

directory which contains spice netlist of each logic cell.
