Circuit and Symbolic Extraction from VLSI Layouts of Arbitrary Shape

임의의 각도를 갖는 VLSI 레이아웃에서의 회로 및 심볼릭 추출

This paper presents the design of a layout processing system that performs circuit and symbolic extraction from hierarchical designs containing arbitrarily shaped layout. The system is flexible enough to deal with various technologies, MOS or bipolar, by providing extraction rules in the form of technology files. In this paper, new efficient algorithms for trapezoidal decomposition of polygon and symbolic path extraction using trapezoidal template are proposed for symbolic extraction. Circuit and symbolic extractor is developed as an integrated design environment of SOLID system.
