Open Cell and Free PDK Libraries

Silvaco’s Open-Cell and FreePDK Libraries are available to Universities and Si2 Members at no charge.

This library aligns with the current generation of silicon process nodes and is based on the FreePDK process design kit from Silvaco. This PDK does not contain proprietary or sensitive data that would prohibit free sharing of a library built with it. The new Silvaco cell library is free for all non-commercial purposes and is particularly suited to research programs and standards development organizations that have previously had free access only to libraries with much older process technologies. These libraries are intended for EDA tool demonstration and are not for actual silicon processing.

15nm Open-Cell Library and 45nm FreePDK

Silvaco’s Open-Cell 15nm and 45nm FreePDK Libraries have been made available to Universities and Si2 Members at no charge.

The 15nm library aligns with the current generation of silicon process nodes and is based on the FreePDK15 process design kit from Silvaco. This PDK does not contain proprietary or sensitive data that would prohibit free sharing of a library built with it. The Silvaco cell library is free for all non-commercial purposes and is particularly suited to research programs and standards development organizations that have previously had free access only to libraries with much older process technologies. The Predictive Technology Model from Arizona State University was used in conjunction with the PDK to characterize the 15nm standard-cell library.

The 45nm FreePDK libraries were 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.

Universities: Please fill out the following request form to obtain access to the 15nm Library and/or to the 45nm FreePDK.
Si2 Members: Please download these libraries from the Si2 Member Portal.
Non-Si2 member companies – please contact Silvaco.
