In real world situations of less-than-perfect process yields, test programs with very high fault coverage are necessary for producing defect-free products. Manual test pattern generation is not practical and most conventional automatic test pattern generation cools do not handle sequential circuits. Thus, the designer is forced to adopt design-for-test (DFT) techniques that turn the sequential circuit into a combinational one. However, these DFT techniques cannot be used in leading edge applications where the circuit performance and the logic density cannot be sacrificed. Fortunately, a solution exists that takes advantage of the hierarchical design methodology commonly employed in the design of complex ASICs. This solution automatically produces test patterns for sequential circuits without requiring use of DFT techniques. The Test Design Expert (TDX) from ExperTest, uses an expert-systems approach by utilizing the behavior description of the ASIC to generate the test vectors for faults modeled at the gate level. TDX generates high quality test patterns for sequential circuits, including asynchronous ones, by understanding the function of the circuit from the behavior description written in VHDL. The advantage of this methodology is that the designer does not have to change the design methodology and is not restricted by the constraints of a specific DFT technique. Test development proceeds along with the logic design and no special requirements are imposed on the manufacturing process.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"46 1","pages":"97-101"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87354215","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 author gives an introduction to the critical issues of supplying parts and component data. He focuses on identifying the principal data requirements for EDA tools and the issues affecting the supplying of parts and component data by vendors and the use of these data by design teams. New design methodologies, like concurrent engineering, require new types and increasing achieving amounts of data. Further, they require the data to support all disciplines to be available earlier in the development process. Many critical technical issues can hinder the supplying of the part and component data necessary to support the new tools and design methods. Most important of these issues is defining the standards for part and component data and the standards for tool interfaces. Other critical technical issues include the balance between supplying the detailed data and protection of supplier's proprietary information, training designers on the new tools and the detailed parts design data, and the methods for validation of data and product designs.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"98 1","pages":"117-122"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86071968","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}

Further, early design decisions are a major determinant of systems cost and performance. More than 80% of the life-cycle cost of a system will have been determined by the end of the design phase. Recognition of these two facts has highlighted the need for better R/M/T design capabilities. Increasing cooperation among the various computer-aided R/M/T processes will aid in decreasing life-cycle costs and improving the quality of design. Recognizing this, Rome Air Development Center (RADC) has pursued the development of several computer-aided R/M/T procedures. Several critical issues remain before the full benefit of these tools to concurrent engineering can be realized. These issues include: access to current design information by reliability and maintainability (R&M) engineers, communication of R&M data among the several design participants, and the need for timely and relevant data. The software tools described in this paper can have a positive impact on the evolution of the design process, but only if fully integrated into a concurrent engineering environment.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"11 1","pages":"83-91"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86114256","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 major barriers to industry-wide acceptance of concurrent engineering have been found to be management misunderstanding of the applications of the concepts involved and a lack of clear direction to its implementation, and a reluctance to change by the engineering professionals involved. A change in total corporate culture is required to eliminate these barriers. The principal conclusion reached is that the current push to introduce total quality management (TQM) into a company can be used as the driver for the integration of all engineering and manufacturing functions into a concurrent engineering operation. Concurrent engineering becomes an enabling technology for total quality management. Further, disciplines such as reliability, maintainability, and computer-aided engineering become the enabling technologies for concurrent engineering. The acceptance of the changes required in corporate culture leads to the natural introduction and evolution of new technology driven by total quality management. This evolution has resulted in a smooth transition from isolated product generation functions into a totally integrated design, test and manufacturing operation.<<ETX>>","PeriodicalId":59272,"journal":{"name":"计算机辅助工程","volume":"1 1","pages":"131-134"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91252594","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}
