一、Cadence GPDK

The Cadence Generic Process Design Kits (GPDK) provide device and semiconductor process level information for use with Cadence Virtuoso L, XL, and GXL products. The semiconductor processes represented by these GPDKs are fictitious and do not represent any actual semiconductor process. There are three GPDKs provided by Cadence, representing typical 45nm, 90nm, and 180nm design kits.

Download GPDK updates from Cadence's support site. You'll need the current Cadence Reference Key.

二、NC State University Cadence Design Kit

  NC State University’s Cadence environment has been customized with several technology files and a fair amount of custom SKILL code. These files contain information useful for analog/full-custom digital CMOS IC design via the MOSIS IC fabrication service. This information includes layer definitions (e.g. colors, patterns, etc.), parasitic capacitances, layout pcells, SPICE simulation parameters, Diva rules for DRC, extraction, and LVS verification, and various GUI enhancements. This environment is available as the NCSU Cadence Design Kit(NCSU CDK).

  The NCSU CDK can be used with at least versions 4.4 through 5.1 of the Cadence software toolset and is available free of charge as a service to the Cadence design community.

The original NCSU CDK was authored by Toby Schaffer, Alan Glaser, and Andy Stanaski in 1996. Their good work has been sustained and supported by many others since then.

  Support for this effort comes from DARPA, NSF, SRC, and the NCSU Analog Alliance. The effort is directed by Professor Paul Franzon and Professor Rhett Davis.

三、SkyWater Open Source PDK

  The SkyWater Open Source PDK is a collaboration between Google and SkyWater Technology Foundry to provide a fully open source Process Design Kit and related resources, which can be used to create manufacturable designs at SkyWater’s facility.

  As of May 2020, this repository is targeting the SKY130 process node. If the SKY130 process node release is successful then in the future more advanced technology nodes may become available.

  The SkyWater Open Source PDK documentation can be found at               <https://skywater-pdk.rtfd.io>.
