Description

Introduction

Synopsys IC Validator is a signoff-grade physical verification solution widely used in advanced semiconductor design flows. It ensures design correctness and manufacturability before tapeout through checks like DRC, LVS, and advanced rule verification. Moreover, it is tightly integrated with physical design environments, and therefore it enables accurate and efficient signoff closure. In addition, it helps reduce silicon defects, while also improving overall design quality.
