Design and development paradigm for industrial formal verification CAD tools

CAD tool designers have given priority to providing features that will let circuit and logic designers use this custom-memory formal verification and analysis tool without a steep learning curve. This article discusses a few fundamental design decisions behind the successful deployment of a second-generation formal custom-memory equivalence-checking tool, Versys2, in the PowerPC design flows. The Versys2 symbolic simulator was developed at Motorola for verifying equivalence between register-transfer-level (RTL) designs and custom transistor circuit schematics
