ProperCAD: A portable object-oriented parallel environment for VLSI CAD

摘要: Most parallel algorithms for VLSI CAD proposed to date work efficiently only on machines that they were designed for. As a result, these are dependent the architecture which developed and do not port easily other architectures. In an effort address this problem, we developing Portable object-oriented environment (ProperCAD). The objectives of research two-fold: 1) To develop new run in portable environment. We accomplish two stages. First, using general purpose platform programming called CHARM at University Illinois. Concurrently, C++ is truly specialized applications; 2) design around good sequential algorithm with well-defined parallel-sequential interface. This will permit benefit from future developments algorithms. approach described one application has been implemented as part project-ProperEXT: flat extractor circuits. algorithm, its implementation, performance ProperEXT range presented. implementation across variety platforms without change. It currently runs Encore Multimax, Sequent Symmetry, Inter iPSC/2 i860 hypercubes, NCUBE 2 hypercube network Sun Sparc workstations. >
