Help, someone. RED SKY130pdk TT_ models block. #160

Closed timibacco closed 8 months ago

Hi , can anyone help explain why the tt models block for the sky130 tops is red on xschem startup. Red is not a good color. Can someone help out? This is a screenshot though. Screenshot from 2024-02-03 14-05-15

Plus I also get this warning as well.At Xschem's startup as well.

Seems like an ngspice configuration, I guess, but I really don't know what resources to check out anymore.

You have an old xschem version installed on the system. Remove the old xschem: sudo apt purge xschem then install xschem sources from git and build the program. Read the instructions here: https://xschem.sourceforge.io/stefan/xschem_man/install_xschem.html

Thanks very much. Worked like Xschem.
