@User @User i have set up a (29') with step by step instruction to build

xschem

, the

xschem_sky130

symbol libraries (transistors, devices, standard cells) , install the

skywater-pdk

process files, and build the

ngspice

simulator from sources. I think this will be useful for new users to bootstrap a working environment for analog design on the skywater pdk with xschem. I hope it helps.
