Abstract
An apparatus for monitoring the temperature of an integrated circuit device includes a conductive wiring pattern formed on the integrated circuit device, extending into areas of the device to be monitored. A deterministic signal source is configured to generate a deterministic signal along the conductive wiring pattern, with one or more return paths tapped from selected locations along the pattern. A temperature change determination circuit is coupled to the one or more return paths and to a reference signal taken from the deterministic signal source. The circuit is configured to determine a delay between the reference signal and a delay signal traveling through at least a portion of the wiring pattern and a corresponding one of the return paths.
