Abstract
A method is presented for characterizing a digital circuit for determining an optimum operating point of the digital circuit. The digital circuit includes sequential elements; conducting data paths; a clock tree; a time fault sensor receiving as input a data signal and configured to detect during a detection window a transition of the data signal; and a system for setting first and second operating parameters of the circuit. The method includes a) activating a conducting data path leading to the sequential element coupled to the sensor; b) determining, for a given value of the first parameter, a first value of the second parameter from which the sensor detects a transition of the data signal during the detection window, the values of the first and second parameters defining an operating point of the circuit; and c) correcting the operating point.
