Nangate Open Cell Library


The Nangate 45nm Open Cell Library is a generic open-source, standard-cell library provided for the purposes of research, testing, and exploring EDA flows. This library is purposely non-manufacturable.

Nangate has developed and donated this library to Si2 for open use. The library is intended to aid university research programs and organizations such as Si2 in developing flows, developing circuits and exercising 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 the different cell functions come in multiple drive strength variants end up with more than 100 different cells in the library.
