Open-Source CMOS Resources
SkyWater has partnered with Google to create the first open-source process design kit, called SKY130, based on our 130nm CMOS platform.
Open source SKY130 PDK on Github
Github hosts the SKY130 Open Source PDK. There you can find key information, links to resources needed to get started quickly, and support. The SKY130 PDK is supported by a dedicated and talented group who are equally excited by the opportunity of making chip development available to everyone.
