摘要：Since the complexity of electrical system has been aggravated as the deep-submicron technology in chip manufacturing continuously develops, chips are far more likely to be affected by various faults. Effective on-line testing method is a great challenge for high reliability system design. We propose a novel test structure based on Software Based Self-Test (SBST) to implement on-line test with low overhead. This test structure adopts a microprocessor to apply test stimulus, analyze test response and manage the test process. The microprocessor should define the specific test instructions and primarily accomplish the self-test for verification its own function. Test vectors of some modules are generated by TetraMAX for achieving high fault coverage and reducing area overhead. The on-line test results of a LVDT module for avionics control system show the efficiency and flexibility of proposed test scheme.
