LOGIC BUILT-IN SELF-TEST OF AN ELECTRONIC CIRCUIT

A tool for performing a logic built-in self-test of an electronic circuit operating on a clock cycle basis. The tool stores a configurable test signature in a random-access memory together with a pattern counter for a test pattern, wherein a number of the at least one additional signature register corresponds to a number of entries in the random access memory. The tool determines an error based, at least in part, on a compare operation for a given test pattern, wherein the compare operation determines whether the test signature in the first signature register before a capture cycle of a next test pattern differs from the corresponding configurable test signature. The tool stores the error in a corresponding additional signature register.
