抄録
Although many electronic safety-related systems require very high reliability, it is becoming harder and harder to achieve it because of delay-related failures, which are caused by decreased noise margin. This paper describes a technology named DART and its implementation. The DART repeatedly measures the maximum delay of a circuit and the amount of degradation in field, in consequence, confirms the marginality of the circuit. The system employing the DART will be informed the significant reduction of delay margin in advance of a failure and be able to repair it at an appropriate time. The DART also equips a technique to improve the test coverage using the rotating test and a technique to consider the test environment such as temperature or voltage using novel ring-oscillator-based monitors. The authors applied the proposed technology to an industrial design and confirmed its effectiveness and availability with reasonable resources.
