GapFree is ideal for high-consequence systems where thorough verification is paramount to managing liability risks associated with functionality, security and functional safety. It allows for early verification to commence, ensuring steady and reliable progress until completion.
GapFree employs transactional assertions that encompass the entire circuit behavior, ensuring thorough coverage. A completeness checker rigorously identifies and addresses any verification gaps, ensuring that no aspect of the design is left unchecked. It meticulously identify specification gaps and close them with appropriate transactional assertions, which are then verified against the register transfer level (RTL). Any weak transactional assertions are pinpointed, strengthened and subsequently verified to maintain robustness and accuracy. Any missing transactional assertions are identified, hints to develop them are provided and later, they are thoroughly verified against the RTL.
