At the heart of the problem is the need by IP providers to protect their development investment. Few IC designers can afford to pay the often high price for access to IP source code, so IP suppliers provide significantly less costly 'black box', or encrypted, versions for use with specific design tools. The problem with this is not only that the IP vendor is saddled with the cumbersome task of maintaining multiple IP core versions for various tool sets, but, more importantly, that it is an incomplete solution. To address the need for a means to protect IP from piracy while making it easier for the IF supplier to deploy and the IC designer to use, Synplicity has developed and introduced an open IP encryption/decryption methodology. It takes advantage of features in the most recent release of Verilog and commonly used encryption mechanisms in a new usage model that could become an industry standard.","PeriodicalId":132835,"journal":{"name":"Electronic Systems and Software","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127729554","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 new approach is most concisely described as the use of event-identification software. Essentially, it is smart software that scans each waveform acquired by the oscilloscope and looks for various signal-integrity issues or events of interest in the signal. The software-based approach has a number of potential benefits. The use of software to pick up issues means that multiple events can be monitored simultaneously. Hardware triggering is limited to identifying a single event of interest. The hardware trigger circuit is setup to trigger on a specific type of event and is prohibited from monitoring for other types of event at the same time. Event-identification software does not suffer from such a limitation. It can be programmed to scan for five events at the same time on any channel or combination of channels. This can significantly reduce the time it takes to narrow down the potential causes of a signal integrity problem or isolate nasty interdependent events.","PeriodicalId":132835,"journal":{"name":"Electronic Systems and Software","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122599162","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}
