This site hosts predictive transistor model files developed in the PTM project. PTM evolved from the earlier Berkeley Predictive Technology Model by the Device Group, University of California, Berkerley. From 2005 to 2012, PTM developed models for bulk CMOS and FinFET devices, scaling down to the 7nm node.
