Abstract
Arbiter circuits placed between two signal path segments on a semiconductor chip to measure the difference in propagation delay between those paths at their beginning and end. Each arbiter circuit has two inputs, and outputs signals indicating which of its inputs is the first to receive a leading edge of an input transition. External circuitry monitors the arbiter outputs, and accordingly controls the application of the input transitions. By varying the delay of the input signal paths, the relative propagation delay can be determined.
