众所周知，电路分析技术是电路设计师强有力的工具，在小型机上实现电路分析程序将更有利于它的广泛应用。本文介绍的 ＧＣＡＰＮ是运行在具有磁盘操作系统 ＲＤＯＳ的ＤＪＳ—１３０机（或ＮＯＶＡ机）上的通用电路分析程序，该机具有３２Ｋ内存，字长为１６位。 ＧＣＡＰＮ有一个直观易学的输入语言，采用了“改进节点法”建立电路方程，应用稀疏矩阵技术和隐式变步长的积分方法来求解方程组。程序中对“改进节点法”作了若干改进，并采用了适于小型机特点的数据结构和软件技术。另外，程序中还备有ＭＯＳ和双极型晶体管的模型。用ＧＣＡＰＮ可以进行直流、交流和瞬态分析
As we all know, circuit analysis technology is a powerful tool for circuit designers, in the minicomputer circuit analysis program will be more conducive to its wide range of applications. The GCAPN introduced in this article is a general-purpose circuit analyzer running on the DJS-130 (or NOVA) with the disk operating system RDOS, which has 32K of memory and has a word length of 16 bits. GCAPN has an intuitive and easy-to-learn input language, uses the improved node method to establish circuit equations, applies sparse matrix technique and implicit variable step-size integral method to solve the system of equations. Procedures for the “improved node method” made some improvements, and used for the characteristics of the minicomputer data structure and software technology. In addition, the program is also equipped with MOS and bipolar transistor model. Use GCAPN for DC, AC, and transient analysis
