Abstract
A computer executable tool analyzes unknowns (Xs) in gate-level simulation and traces their sources to determine if the Xs are generated due to X-pessimism. For Xs generated due to X-pessimism, fixes are generated to correct simulation results. Corrected simulation results match real hardware behavior and greatly reduce the analysis effort of engineers.
