Hello All, I was trying to simulate our design using SPICE. I needed the model files for NMOS and PMOS of skywater 130 nm pdk. I searched the website and it says that the model files for the SPICE is ready to use but upon checking the git hub open source I could not manage to get those model files. I would really appreciate anyone of you helping me to get those model files for PMOS and NMOS. Thanks in advance!!

https://github.com/The-OpenROAD-Project/OpenLane/blob/master/docs/source/manual_pdk_installation.md install skywater PDK from link and search for models

Once you have the PDK installed by open_pdks, the way to include the models is with the SPICE line

.lib <path_to_pdk>/sky130A/libs.tech/ngspice/sky130.lib.spice tt

But the MOSFETs for this process are "micro-binned" (a huge amount of model data), and so to keep the simulation from taking several minutes to start, make sure you copy this file:

<path_do_pdk>/sky130A/libs.tech/ngspice/spinit

to the directory where you are running ngspice, and rename it to

.spiceinit

. All these instructions assume that you are using ngspice. The models have also been tested and should work with Xyce.

Thank you Tim Edwards and Vijayan Krishnan for your suggestions. I am actually using LTspice. Will the installation process work with LTspice too?

I have no idea.

Tim, I'm actually not seeing the sky130A/libs.tech/ngspice/spinit file in my system
