Open-source process design kits (PDKs) that this course’s tool chain targets.
The two manufacturable PDKs — Sky130 and GF180MCU — are full foundry-signed, distributed via ciel, and backed by free multi-project wafer runs. ASAP7 is a predictive PDK used for research and EDA benchmarking; it is not manufacturable.
- Sky130 PDK — SkyWater 130 nm. The workhorse for open-source digital tape-outs since 2020. 1.8 V core, five routing metals plus a local-interconnect layer, HD standard cells.
- GF180MCU PDK — GlobalFoundries 180 nm mixed-signal / MCU process. 3.3 V and 6 V devices, three metal-stack variants (A/B/C/D), used by wafer.space MPW runs.
- ASAP7 PDK — ASU/ARM predictive 7 nm FinFET. Four V_T flavors, 9 routing metals, BSIM-CMG models. Research-only — no foundry, no tape-out, no MPW.
