Publication number: 20130035891Abstract: A second computing device determines whether or not a conflict occurs wherein at least two of a plurality of first computing devices set different request values to an input point to which a request value is to be set, based on the request value stored in the request value buffer. When it is determined by the second computing device that a conflict occurs wherein one of the plurality of first computing devices is about to set a request value different from a request value that is set to that input point by another first computing device, the one of the first computing devices stops setting the request value. This prevents any increase in the test pattern count due to parallel processing.Type: ApplicationFiled: May 4, 2012Publication date: February 7, 2013Applicant: FUJITSU LIMITEDInventor: Daisuke Maruyama
