Abstract
A system and method for detecting soft-failures in integrated circuits is provided. A circuit includes a combinatorial logic block having a first signal input and a second signal input, and a latch coupled to an output of the combinatorial logic block. The combinatorial logic block produces a pulse when only one of either a first signal provided by the first signal input or a second signal provided by the second signal input is a logical high value, and the latch captures the pulse if the pulse has a pulse width greater than a second threshold. The pulse has a pulse width that is based on a timing difference between a first signal transition on the first signal and a second signal transition on the second signal, the combinatorial logic block produces the pulse if the timing difference is greater than a first threshold, and the combinatorial logic block operates with balanced inputs.
