In this paper we present a method for path delay fault testing of multiplexer-based shifters. We show that many paths of the shifter are non-robustly testable and we give a path selection method so as all the selected paths to be robustly testable by 20 * log2n + 2 test-vector pairs, where n is the length of the shifter. The propagation delay along all other paths is a function of the delays along the selected paths.
