| 20090319252 | METHOD AND APPARATUS FOR EXTRACTING ASSUME PROPERTIES FROM A CONSTRAINED RANDOM TEST-BENCH - One embodiment of the present invention provides systems and techniques to extract assume properties from a constrained random test-bench. During operation, the system can receive a constrained random test-bench for verifying the design-under-test (DUT), wherein the constrained random test-bench includes a statement which assigns a random value to a random variable according to a constraint. Next, the system can modify the constrained random test-bench by replacing the statement with another statement which assigns a free input variable's value to the random variable. The system can also add a statement to the constrained random test-bench that toggles a marker variable to localize the scope of the statement. The system can then generate an assume property which models the constraint on the free input variable. The assume property can then be used by a formal property verification tool to verify the DUT. | 12-24-2009 |
