本文介绍一个能在小型机上运行的逻辑模拟系统程序——LSSP.该系统包括逻辑模拟和定时模拟,以适应不同的模拟精度的要求.该系统描述语言简单易懂,有丰富的基本单元,数据结构和模拟算法均考虑到小型机内存小、速度慢的特点.通过对16位运算功能发生器的实际模拟表明,该系统使用方便,模拟速度也较快,能模拟1000个门以上的逻辑电路.采用通用的FORTRAN-Ⅳ语言编写程序,便于移植推广使用。
This article introduces a logic simulation system program that can run on the minicomputer - LSSP. The system includes logic simulation and timing simulation to meet the requirements of different simulation accuracy. The system description language is easy to understand, rich in basic units, data The structure and simulation algorithms all take into account the small memory and slow speed of minicomputer.Through the actual simulation of 16-bit computing function generator, it shows that the system is easy to use and the simulation speed is fast, which can simulate more than 1000 logic circuits Using common FORTRAN - Ⅳ language to write programs, easy to transplant and promote use.
