Description

Introduction

IC Validator is a comprehensive physical verification solution. It is used for signoff-quality Design Rule Checking (DRC), Layout vs Schematic (LVS), and advanced reliability verification. Moreover, it supports hierarchical and distributed processing. Therefore, it enables efficient final signoff for advanced-node and large-scale IC designs.

In addition, it is widely used in tapeout flows to ensure manufacturing readiness, rule compliance, and netlist integrity before final GDSII release.
