Many programs for analyzing electronic circuits including nonlinear elements have been reported. It became difficult to evaluate circuits such as ICs by the breadboard method, because this method is not always suitable for simulation of high speed and high density circuits. Moreover lengthy experiments are involved. In the case of circuits composed of discrete parts, it was considered that many manual experiments could be replaced by computer aided analysis. We developed a general nonlinear network analysis program NONLISA to enable the use of medium scale computer system FACOM 270-30 for scientific and technical applications. This program is aimed mainly at the capability of circuit designers' easy treating and extending system functions without many modifications. Functions of NONLISA are DC analysis, transient analysis, sensitivity analysis, worst case analysis, Monte Carlo Simulation etc. for networks including nonlinear elements.
This paper deals with the structure and the functionsof NONLISA.
已经报道了许多用于分析包括非线性元件的电子电路的程序。用面包板方法评估诸如IC之类的电路变得很困难，因为这种方法并不总是适用于高速和高密度电路的仿真。此外，涉及冗长的实验。在电路由分立部件组成的情况下，人们认为许多人工实验可以用计算机辅助分析代替。我们开发了一个通用的非线性网络分析程序NONLISA，以使中型计算机系统FACOM 270-30可以用于科学和技术应用。该程序的主要目的是使电路设计人员能够轻松处理和扩展系统功能，而无需进行很多修改。对于包括非线性元件的网络，NORNLISA的功能包括直流分析，瞬态分析，灵敏度分析，最坏情况分析，蒙特卡洛模拟等。
本文探讨了NONLISA的结构和功能。
