The NanGate Open Cell Library is a generic open-source, standard-cell library for research, testing, and exploring EDA flows. This library is purposely non-manufacturable.
This library is contributed to Si2 for open use by NanGate to demonstrate their tools. It’s for demonstration purposes only, not commercial use.
The library is intended to aid university research programs and organizations such as Si2 to develop flows and circuits, and exercise new algorithms. In its first release, the Open Cell Library contains 38 different functions, ranging from buffers to scan flip-flops with set and reset. All cell functions come in multiple drive strength variants end up with more than 100 different cells in the library.
The library was generated using NanGate’s Library Creator™ and the 45nm FreePDK Base Kit from North Carolina State University. Characterization was done using the Predictive Technology Model from Arizona State University. The FreePDK Base Kit is supported by Professors Rhett Davis and Paul Franzon and their research teams and is available for download.
Because the library was generated using a non-optimized Open PDK, it was not created to be an optimized library for any real-life applications.
