BAG (BAG AMS Generator) Primitives Library for SKY130

This repository contains the required primitives to use the BAG3 framework with the SkyWater proprietary S8 130nm PDK. You can get access to this PDK through signing an NDA and legal agreement with SkyWater Technologies.

This repository also contains a work in progress to make these primitives and the BAG3 framework compatible with the Google skywater-pdk, a fully open source, manufacturable PDK for SkyWater's 130nm (SKY13) process node.

When combined with appropriate generator code, the primitives enables the creation of analog integrated circuits that are manufacturable at SkyWater Technologies commercially or through programs like Google's no-cost MPW shuttle program for open source designs, done in collaboration with efabless.

What is BAG?
