8. PDK directory

8.1. asap7

The asap7 PDK was developed at ASU in collaboration with ARM Research. With funding from the DARPA IDEA program, the PDK was released a permissive open source PDK in 2021. The PDK contains SPICE-compatible FinFET device models (BSIM-CMG), Technology files for Cadence Virtuoso, Design Rule Checker (DRC), Layout vs Schematic Checker (LVS) and Extraction Deck for the 7nm technology node. For more details regarding the technical specifications of the PDK, please refer the PDK documentation and associated publication. Note that this process design kit is provided as an academic and research aid only and the resulting designs are not manufacturable.

PDK content:

open source DRM
device primitive library (virtuoso)
spice (hspice)
extraction runsets (calibre)
drc runsets (calibre)
APR technology files
7.5 track multi-vt standard cell libraries

The freepdk45 PDK is a virtual PDK derived from the work done at NCSU (NCSU_TechLib_FreePDK45.) It supplies techfiles, display resources, design rules and scripts to permit layout design and rule checking for a generic 45 nanometer process. The technology information contained in this kit has been compiled from published papers, predictive technology models and rule scaling. This information may be freely used, modified, and distributed under the open-source Apache License (see the file APACHE-LICENSE-2.0.txt in the root install directory for the complete text). This technology is intended to work with the 45nm BSIM4 Predictive Technology Model from Arizona State University (https://ptm.asu.edu/). See the HSPICE Models section of this file for details about these models.
