What is detailed routing and DRC in VLSI layout?
Detailed routing defines the exact metal layer interconnect paths for standard cell connections. Design Rule Checking (DRC) is a physical verification step that checks these routes against manufacturing constraints like minimum spacing and metal widths.
Introduction to Detail Routing and Design Rule Checking (DRC)
Understanding the details of Detail Routing and Design Rule Checking (DRC) is essential for front-end verification, DFT testing, or backend timing closure in modern sub-micron silicon processes.
This daily knowledge byte offers concise definitions, architectural outlines, and practical design solutions to support your engineering career.
Core Technical Fact Card
