We present an update on BAG, a framework for the development of process independent Analog and Mixed Signal (AMS) circuit generators. Such generators are parametrized de- sign procedures that produce schematics, layouts, and verification testbenches for a circuit given top level specifications. We describe a universal AMS circuit verification framework built with BAG, and two new layout engines, XBase and Laygo, that enables pro- cess independent layout generation. We have developed various complex circuit generators as driving examples, including a time- interleaved SAR ADC and a SerDes transceiver frontend, taped out in TSMC 16nm FFC process. We also verify our claims of process portability by presenting layouts generated in various technology nodes, including TSMC 28nm, TSMC 16nm, TSMC 7nm, Global Foundries 45nm RF-SOI, and ST 28nm FD-SOI.
