SkyWater SKY130

Foundry-linked open PDK

Experimental open release

Open PDK for SkyWater's 130 nm CMOS process. It supports manufacturable designs, while the public release remains an experimental preview rather than a production-qualified kit.

GlobalFoundries GF180MCU

Foundry-linked open PDK

Experimental open release

Open PDK for GlobalFoundries' 180 nm MCU process. It targets manufacturable designs at GF, but the public release remains an experimental preview not intended for production use.

IHP SG13G2
