Abstract
An integrated circuit includes secure logic that requires protection. Secure assurance logic protects the secure logic. The secure assurance logic includes a plurality of protection modules that monitor the occurrence of insecure conditions. Each protection module monitors a different type of insecure condition. Each protection module asserts an alarm signal when an associated insecure condition is detected. The alarm signals asserted by the plurality of protection modules are stored.
