本文描述了一个用于MOS集成电路工艺的电路提取程序CEXTOR.CEXTOR将集成电路的版图自动地转换为适合作精确电路模拟的电路描述.该程序能进行内部连接电阻,内部节点电容和晶体管尺寸的计算.本文提出的由矩形局部替代任意多边形的技术和连接与电阻同时提取的方法都改善了电路提取的速度.目前,CEXTOR已由FORTRAN-77编制程序,并在PCS,QU-68000计算机上实现. This article describes a circuit extraction program for MOS integrated circuit technology, CEXTOR. CEXTOR automatically converts the layout of an integrated circuit into a circuit description suitable for accurate circuit simulation. The program can perform internal connection resistance, internal node capacitance, and transistor size The proposed method of replacing arbitrary polygons by rectangles and the method of connecting and resistance extraction at the same time improve the speed of circuit extraction.Currently, CEXTOR has been programmed by FORTRAN-77 and implemented on PCS and QU-68000 computers .
