Miller (see IEEE Trans. on Computers, vol.C-35, no.8, p.760-71, Aug. 1986) observed that the checkpoint faults are not sufficient target faults for test generation in combinational circuits and presented an algorithm to select the additional target faults so as to ensure sufficiency. A critical review of their algorithm is presented, and certain disadvantages of that algorithm are brought to light. A revised algorithm incorporating an additional stage of fault simulation and judicious selection of noncheckpoint target faults based on a probabilistic model is developed. The concepts of cover forest and benefit indicators are developed and used effectively in guiding the judicious selection of noncheckpoint target faults, thus minimizing the total number of calls made to the test generation routine.<<ETX>>","PeriodicalId":6453,"journal":{"name":"[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems","volume":"13 1","pages":"619-622 vol. 2"},"PeriodicalIF":0.0,"publicationDate":"1991-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76841709","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}

This scheme basically exercises access control for the incoming calls. In this scheme, an incoming call is accepted only if its resource requirement is not more than a certain predefined percentage of the remaining resources at the intermediate points of a BISDN (broadband integrated services digital network). The authors simulate this scheme for a simple network and present results in terms of blocking probabilities as the arrival rates of different kinds of calls are varied. Some results are shown in terms of effects of varying the threshold on the blocking probabilities. Some of the effects are depicted in terms of delay histograms for different situations. Generally, the results show that the calls with higher bandwidth requirements are affected the most as compared to the calls that have lower bandwidth requirements. The model developed is useful in the design of BISDN that can handle a wide variety of traffic characteristics of different applications.<<ETX>>","PeriodicalId":6453,"journal":{"name":"[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems","volume":"65 1","pages":"997-1000 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1991-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75930272","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}
