Description

Introduction

Synopsys Custom Compiler is a next-generation custom IC design platform used for schematic capture, layout editing, and full-custom or analog IC implementation. In addition, it provides a unified environment that tightly integrates Process Design Kits (PDKs), technology libraries, and signoff verification tools. Therefore, it enables a seamless design-to-fabrication workflow.

Moreover, the tool supports advanced technology nodes and offers a highly interactive design environment. As a result, it is widely used for analog, mixed-signal, RF, and custom digital block design. Overall, it improves productivity and design accuracy across complex IC projects.
