Custom integrity checks find early IC design implementation errors

Early-stage mistakes and out-of-sync data can limit a design team’s productivity. Technology-agnostic design integrity checks enable designers to find and fix gross and systemic issues before initiating downstream applications.

Custom design rule checks help verify IC design integrity in early-stage verification flows

While standard foundry design rule decks are necessary to ensure manufacturability, complete reliance on signoff design rule checking at early design stages where dirty data is common is not always the most efficient process. Running a foundry deck on incomplete blocks, out-of-sync data, or a known “dirty” design creates long runtimes and huge error sets. Developing a simple set of customized design integrity checks targeting specific issues during early-stage verification can eliminate gross and systemic design errors earlier in the design flow.
