Abstract
Systems and methods are provided for verifying the integrity of test functionality for an integrated circuit design. This may be achieved, for example, by analyzing the integrated circuit design to identify a driver element that outputs a security signal for controlling the test functionality, analyzing the integrated circuit design to identify an input stage of one or more elements that feed the driver element, monitoring the security signal over a range of values for the input stage, and determining that an error exists in the test functionality if a change in the security signal is detected during the monitoring.
