XSCHEM Device symbols for the Google-Skywater SKY130 Process Design Kit (PDK)

Warning: This is currently Work in progress.

This directory contains symbols to be used in the XSCHEM schematic editor. For a quick XSCHEM introduction see this presentation.
These symbols represent the available silicon devices as documented on the Skywater-pdk website in the device details section.

GOAL

Provide a set of symbols that can be used to draw circuit schematics in XSCHEM. Netlists in various target formats can be extracted for simulation or Layout vs Schematic checks. The set of symbols is designed to correctly link to the Skywater PDK model files, allowing to seamlessly simulate the circuit with SPICE simulators. A good tutorial for starting with xschem and Sky130 pdk can be found here. Thanks Bluecmd!

SYMBOL DRAWINGS

Up to now this is the list of devices that have been created. There are a lot of missing devices, as this is a work in progress and the whole PDK is evolving.
