Today, electronic devices are increasingly employed in different fields, including safety- and mission-critical applications, where the quality of the product is an essential requirement. In the automotive field, the Software-Based Self-Test is a dependability technique currently demanded by industrial standards. This paper presents an approach employed by STMicro electronics for evaluating, or grading, the effectiveness of Software-Based Self-Test procedure used for on-line testing automotive microcontrollers to be included in safety-critical vehicle parts, such as in airbags and steering systems.
