Layout design verification gets exponentially harder with each new process technology node as new manufacturing constraints impose new design layout requirements. The impacts have been particularly difficult on custom and analog/mixed signal (AMS) layout designers. A tool that allows designers to receive immediate signoff DRC feedback on a layout configuration gives them more time and freedom to optimize and improvise, enabling them to improve the quality of their layouts while maintaining or reducing their tapeout schedules.
The Calibre RealTime Custom interface enables custom/AMS layout designers to access Calibre signoff DRC in the design flow, using full foundry-qualified Calibre rule decks and analysis engines. As designers create and edit the layout design, the Calibre RealTime Custom interface provides immediate signoff DRC feedback, enabling them to minimize design cycle time while creating improved layouts. Designers can also use the Calibre RealTime Custom in-design DRC to learn new rules faster, apply what-if analysis to improve their layouts, run multiple rule decks or specified groups of rules easily and quickly, and debug full-chip errors on the fly during tapeout.
