  • Digital system for the detection of variations in operating conditions of an integrated circuit
    Patent number: 9303953
    Abstract: 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.
    Type: Grant
    Filed: February 4, 2013
    Date of Patent: April 5, 2016
    Assignee: TEXAS INSTRUMENTS INCORPORATED
    Inventors: William C Wallace, Alok Anand, Ravi Srivaths, Chillara Kiran Kumar, Aruna Koityar
