Abstract

Algorithmic test generation for high fault coverage is an expensive and time-consuming process. As an alternative, circuits can be tested by applying pseudorandom patterns generated by a linear feedback shift register (LFSR). Although no fault simulation is needed, analysis of pseudorandom testing requires the circuit detectability profile.
