What is eqDRC?

Abstract

Traditional design rule checking (DRC) uses one-dimensional measurements of features and geometries to determine rule compliance. As feature sizes decrease and design complexity increases, analysis and verification become increasingly difficult. Equation-based DRC (eqDRC) extends DRC technology with a programmable modeling engine. Using eqDRC, users can define multi-dimensional feature measurements with flexible mathematical expressions that can be used to develop, calibrate, and optimize models for design analysis and verification.
