As an example for such a modeling technique, extended predicate/transition nets (Pr/T-Nets) are introduced. These nets can combine modeling in a declarative way by means of first order logic with an operational interpretation inherited from Petri nets. The added concepts of hierarchy and recursion allow the description of extremely complex systems. Three applications of Pr/T-Nets are shown: control of complex design systems, timing analysis, and the implementation of communication protocols.<<ETX>>","PeriodicalId":339176,"journal":{"name":"Proceedings of EURO-DAC 93 and EURO-VHDL 93- European Design Automation Conference","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134112179","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 PEAS-I system is a hardware/software co-design system for ASIP development. The input to the system is a set of application programs written in C language, an associated data set, and design constraints such as chip area and power consumption. The system generates an optimized CPU core design in the form of an HDL, as well as a set of application program development tools, such as a C compiler, assembler, and simulator. A novel method that formulates the design of an optimal instruction set using an integer programming approach is described. A tool that enables the designer to predict the chip area and performance of the design before the detailed design is completed is discussed. Application program development tools are generated in addition to the ASIP hardware design.<<ETX>>","PeriodicalId":339176,"journal":{"name":"Proceedings of EURO-DAC 93 and EURO-VHDL 93- European Design Automation Conference","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123450168","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 output sequence of one or more components of the signature analyzer is monitored, in test mode, by an error detection circuit consisting of a one-cover and a zero-cover. The cover circuits need to detect only such faults that are masked by the signature analyzer. Because of a large number of don't-care conditions for the cover circuits the hardware overhead is very low. All faults in the fault model under consideration are detected either by the cover circuits or, due to an erroneous signature, by the signature analyzer.<<ETX>>","PeriodicalId":339176,"journal":{"name":"Proceedings of EURO-DAC 93 and EURO-VHDL 93- European Design Automation Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115800430","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}

They introduce the concept of a window which is an estimate of the initial placement of a module. There are three phases in the algorithm. In phase one, an initial window for each module is constructed. In phase two, a novel force-directed approach is used to reduce the size of each window in an iterative process so as to determine an initial placement of the modules. In phase three, the same force-directed concept is used to refine the placement. Timing and physical constraints are used in all phases to guide the placement process. The effectiveness of the algorithm is demonstrated by comparing the experimental results with those produced by TimberWolfMC and the GVL algorithm.<<ETX>>","PeriodicalId":339176,"journal":{"name":"Proceedings of EURO-DAC 93 and EURO-VHDL 93- European Design Automation Conference","volume":"353 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131243844","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}
