Abstract-On-line testing is fast becoming a basicfeature of digital systems, not only for critical applications, but also for highly-available applications. To achieve the goals of high error coverage and low error latency, advanced hardware features for testing and monitoring must be iiacluded. One such hardware feature is built-in self-test (BIST), a technique widely applied in manufacturing testing. We present a practical on-line periodic BIST method for the detection of operational faults in digital systems. The method applies a near-minimal deterministic test sequence periodically to the circuit under test (CUT) and checks the CUT responses to detect the existence of operational faults. To reduce the testing time, the test sequence may be partitioned into small sequences that are applied separately-this is especial& useful for real-time digital systems. Several analytical and experimental results show that the proposed method is characterized by full error cover age, bounded error latency, moderate space and time redundancy.
The authors in REF make use of built in self test (BIST) to detect operational faults in the system.
