Abstract
An apparatus may include a delay line having a first delay value corresponding to first operating conditions of the apparatus and a second delay value corresponding to second operating conditions of the apparatus. A monitoring circuit may monitor a time taken for a first clock edge of a clock signal to propagate through the delay line. A determining circuit may determine whether operating conditions of the apparatus are acceptable in response to the time taken.
