Abstract

In one embodiment, the invention is directed to a method of verifying conditions occurring during a simulation of a hardware design. The method comprises logging each occurrence of at least one specified condition in a first log; logging signals observed at an observability port in a second log; and comparing the first and second logs to determine whether for each occurrence of the at least one specified condition logged in the first log, a corresponding entry identifying a signal expected to be observed responsive to occurrence of the at least one specified condition is logged in the second log.
