The first stage is generation of dense placements of FETs (field-effect transistors) from the gate-matrix layouts, using a gate matrix deformation method. The deformation of gate-matrix layouts is guided by the design rules, using FETs with meander channel structures if needed. The second stage is routing of metal wires to connect FETs in modules. The authors have developed a three-dimensional maze router by extending the method to cope with arbitrary multilayer connections with user-defined costs for the connections in each layer. The costs can be used to assign desired priorities for each metal layer in the routing. This method results in about 65% reduction in chip area compared with the gate matrix method for typical examples using three- or four-layer connections","PeriodicalId":165054,"journal":{"name":"1989 Proceedings of the IEEE Custom Integrated Circuits Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114025280","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 method is an acceleration of the standard integral-equation for multiconductor capacitance extraction. These integral-equation methods are slow because they lead to dense matrix problems which are typically solved with some form of Gaussian elimination. This implies that the computation grows like n3, where n is the number of tiles needed to accuracy-discretize the conductor surface charges. The authors present a preconditioned conjugate-gradient iterative algorithm with a multipole approximation to compute the iterates. This reduces the complexity so that accurate multiconductor capacitance calculations grow as nm, where m is the number of conductors","PeriodicalId":165054,"journal":{"name":"1989 Proceedings of the IEEE Custom Integrated Circuits Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131104799","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}

PANDA was developed as a testbed for exploring VLSI design methods and tools. It uses pitchmatching and abutment as the primary assembly technique with channel and river routers available as options. PANDA features a recursive compaction algorithm using depth-first searching, constraint resolution, and wire-length minimization to optimize layout area, while maintaining the input hierarchy. Instead of using a predetermined stand-off distance between cells, PANDA's abutment algorithm calculates the minimum distance required to guarantee no design-rule errors between modules. PANDA has the unique ability to assemble mixed-mode layouts, which are defined as a mixture of fixed-grid cells, such as hand layouts, and symbolic cells (virtual-grid), and places few constraints on the hierarchical description.

The techniques presented allow an analog IC designer to construct a library for cell-based design, as opposed to direct compilation of a full-custom analog/digital IC. Using this approach, the problem of automation is made more tractable, and the result is a more robust, but still flexible, system for mixed analog/digital ASIC (application-specific integrated circuit) design. By combining a study of device scaling issues, careful choice of layout topologies, together with modular construction of cells using lambda based rules, it is possible to extend the lifetime of an analog cell library.
