MOSFET parameters extraction in VDSM ULSI CAD with a parallel-programming strategy

In this paper, we develop an efficient optimization algorithm for MOSFET parameter extraction in VDSM ULSI circuit design, which combines a search-space smoothing strategy, smoothes a large number of local barriers and makes conventional heuristic searching much more efficient. The experiment was implemented with a parallel programming strategy on a distributed multi-computer system with improved computing efficiency. With such an algorithm, we can obtain global solutions much more easily and more accurately than conventional searching algorithms, and parameter extraction automation can make it possible to synthesize simple analog circuits with a small number of transistors
