@Joshua Smith: I have a testbench written for ngspice. How do I run that using Xyce? Also I don't find the modelfile for xyce like it is shipped for ngspice via pdk installer. But I do find separate files for ngspice and xyce in gf180mcu pdk versions (design.ngspice and design.xyce etc). I think the model files for ngspice and xyce are not exactly same cuz I find a few variable name changes etc. Any idea from where I could pick that up to include it in my test bench.

Hmm... yeah I'd have to defer to Eric on this one. Sorry.

@Tim Edwards: When I try to run Xyce, I get such messages when I am trying to use the library ../../sky130A/libs.tech/ngspice/sky130.lib.spice in my testbench. Not sure whether this is the right library that needs to be included inside an Xyce testbench cuz I don't see anything specfic to Xyce like I see something for gf180mcu. Is there something you can help here?

That should work. Your open_pdks installation isn't right. There shouldn't be any lines with

dev/gauss

in the installed PDK. Those lines exist in the original file from google, but they are replaced by hspice/ngspice/Xyce compatible syntax with the

agauss()

function. They also should start at line 51 vs. 49; maybe that difference is a key to why the installation went wrong?

Good catch! I updated my pdk. This error no longer persists. Thank you

Finally checking in here. It looks like this got resolved? If not let me know.

Yep. looks like this got resolved.
