摘要：

A power-on self-test (POST) based on logic built-in self-test (LBIST) has been applied to automotive systems for detecting the latent faults in the field. In an automotive system, the POST is executed during the engine start-up to test the safety-critical devices before starting any functional operations, latent faults (LFs) in the devices can be detected at an early stage. To meet the requirement of the POST, it is necessary to reduce the test pattern volume and improve the fault coverage for logic built-in self-test (LBIST).
