DIGITAL SYSTEM FOR THE DETECTION OF VARIATIONS IN OPERATING CONDITIONS OF AN INTEGRATED CIRCUIT |
摘要 |
A system for detecting tamper events in a digital circuit by having a Critical Path Replica (CPR) circuit operable in parallel with the circuit being monitored, and adjusted to generate a timing violation if the operating parameters of the circuit change to be outside the normal operating parameters. The critical path replica circuit is adjusted to generate a timing violation before the actual circuit being monitored fails due to the changed operating parameters.
