Introduction
Synopsys Custom Compiler is a modern custom IC design platform used for schematic capture and layout design. In addition, it supports full-custom IC implementation with strong integration of verification and signoff tools. As a result, designers can ensure correctness before fabrication. Moreover, the platform supports advanced technology nodes for analog, mixed-signal, and custom digital designs. Therefore, it provides a unified environment for design, analysis, and tapeout preparation.
