Patent 7426705 was granted and assigned to DAFCA on September, 2008 by the United States Patent and Trademark Office.
Assertion checking is achieved by modifying a given set of assertions to include subsuming assertions that cover one or more of given assertions and also require less logic to implement, by implementing at least the subsuming assertions in functionally reconfigurable circuitry within an integrated circuit, and by checking with an auxiliary tester assertions that each of the firing subsuming assertion replaced.
