This paper proposes a novel definition for analog activity coverage and how to measure it in a defect-free circuit for any potential defects (shorts, opens, and parametric). Results are provided for the ITC'17 analog benchmark circuits and show that activity coverage is an approximate upper limit for defect coverage. Other uses for measuring test stimulus quality are discussed, such as assessing burn-in and over-voltage stress stimuli, and ensuring defect tolerance measured for ISO 26262 is accurate.","PeriodicalId":223459,"journal":{"name":"2018 IEEE 23rd European Test Symposium (ETS)","volume":"29 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114114567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The material is based on test and verification services performed for Airbus by a spinoff company of the University of Bremen, as well as on consultancy services delivered by our research group to Airbus and its suppliers. In the context of model-based systems engineering, the test automation approach is currently shifting from manual test procedure programming to model-based testing (MBT), where test cases are automatically identified in models describing the application behavior, allowing for automated test data calculation and test procedure generation. We describe the situations where today's MBT technology is already adequate to increase the effectiveness of automated testing in industry. In addition, we describe some open challenges arising from practical avionic systems testing, where satisfactory solutions still require some research effort.","PeriodicalId":223459,"journal":{"name":"2018 IEEE 23rd European Test Symposium (ETS)","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132463522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
