PQLab

Advanced PDK Verification Platform

Introduction

PQLab is an advanced PDK (Process Design Kit) verification platform. As the semiconductor manufacturing technology continues scaling down to smaller geometries, PDK complexity is increasing rapidly. PDK validation is much more difficult than ever before and takes time.

To address this challenge, Primarius developed PQLab as a complete solution based on years of experience in advanced PDK development and verification. PQLab is an automated QA software for PDKs, featuring a multitude of qualification mechanisms of PDK integrity including technology files, PCell CDF, PCell physical verification (DRC & LVS), and SPICE models. PQLab supports PDK verification from 0.35um to 22nm for the planar process and also from 16nm to 5nm FinFET process, covering the applications in digital logic, analog, high voltage and RF circuits. PQLab helps foundries’ PDK engineers in ensuring PDK quality, and also enables IC designers to easily analyze and qualify foundry PDKs, benchmark between different PDK versions, and different design flows.
