Generally, in such a symbiosis all the functions of the analog computer, which are normally under manual control by the user, here have to be under control of the digital program, except for one case: once the digital program has started an analog computer run, the analog computer is on its own. In the case of combined simulation, i.e., if both computers operate simultaneously, from the viewpoint of the analog computer its digital partner now plays the role of a single, but very complex, computing unit to which some analog signals go and from which other signals come back.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133529496","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}

Nevertheless the integration of cellular circuits of a certain degree of complexity is hampered at present by poor yield, that is by the likelihood that one or more cells of the circuit may turn out to be faulty. It is useful, therefore, to try to use these circuits even when there are some faulty cells. Generally speaking there are two possibilities:\u0000 (a) to provide a certain degree of redundancy in the circuit, so as to be able to replace the faulty cells with spare cells;\u0000 (b) to use, if possible, only the part of the circuit functioning correctly.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116267425","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}
