集成电路时间域上的电特性分析在计算机辅助电路分析中最耗费计算资源.用标准的电路分析程序SPICE2完成一个几百与几千个晶体管以上的大规模集成电路的瞬态分析需要非常长的计算机运算时间,使得电路设计者难以忍受,并且运行时间是与电路的规模按指数关系增长.人们一直在研究与开发一种更为快速精确的电路分析方法,以适应LSI与VLSI设计的发展需要. 电路的瞬态分析需要解一个联立N个方程的方程组,这里N是一个反映电路规模的电路节点数.N越是大,解这个电路方程所需的运算时间就越多.如果将大电路分解为若干个小电路,分别解这些小电路的电路方程,则分析时间将会大大减少.
Analysis of Electrical Characteristics in the Time Domain of Integrated Circuits Costs most computational resources in computer-aided circuit analysis. Transient analysis using a standard circuit analysis program, SPICE2, to complete a large scale integrated circuit of hundreds and thousands of transistors requires a very long Computer operation time makes circuit designers unbearable and operating hours grow exponentially with the size of the circuit People have been researching and developing a faster and more accurate circuit analysis method to accommodate the development needs of LSI and VLSI designs The transient analysis of a circuit requires solving a system of simultaneous N equations, where N is the number of circuit nodes that reflects the circuit scale, and the larger N is, the more computational time it takes to solve this circuit equation, Large circuit is broken down into a number of small circuits, respectively, the circuit solution of these small circuits, the analysis time will be greatly reduced.
