This overlay technique maps design-specific pad locations to a standard grid that can be tested with a universal membrane probe. The proposed approach allows the development cost of a thin-film membrane probe to be shared across many die types, thus reducing the cost and complexity of tooling new die types. An experiment performed to validate this approach is described.<<ETX>>","PeriodicalId":202574,"journal":{"name":"Proceedings 1992 IEEE Multi-Chip Module Conference MCMC-92","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122920156","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 consider the problem of assigning functional blocks into slots on multi-chip modules in high-level design to have fast feedback on the impact of high-level design decisions. A clustering step is used to ensure timing correctness, followed by packing and the K&L algorithm to satisfy capacity constraints while minimizing net crossings. The method is unique in that net crossings are minimized, while satisfying timing and capacity constraints. Test results showed that the method eliminated timing violations and obtained a comparable number of net crossings to that of the algorithm proposed by C.M. Fiduccia and R.M. Mattheyses (1982) with a similar run time. The method can be extended to use partitioning algorithms other than that of Fiduccia and Mattheyses.<<ETX>>","PeriodicalId":202574,"journal":{"name":"Proceedings 1992 IEEE Multi-Chip Module Conference MCMC-92","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130185642","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 development of a silicon waferboard approach has concentrated initially on the development of passively aligned transmitter arrays as a critical test of this technology. The addition of waveguide technology to a silicon waferboard can expand considerably the functionality and flexibility of this technology. Transmitter array development is considered.
