摘 要 近年来，随着计算机应用技术的发展，单片机仿真技术有了很大提高。它能在通用计算机上实现对单片机的硬件模拟、指令模拟和运行状态的模拟，集编程、修改、运行等功能于一体。使用单片机系统仿真软件不仅可以充分利用现有丰富的通用机资源提高实验效率，而且，只需对软件开发系统的部分程序稍作修改，便可升级为新的单片机软件开发系统以满足教学和工程设计的要求。 本课题重点是根据硬件和用户所编写的汇编语言程序，仿真系统的运行过程，实现对固定电路的仿真。即对单片机应用系统硬、软件两部分的仿真。 本论文首先从离散事件系统仿真原理出发，通过四种仿真策略的比较，确定采用进程交互法实现仿真钟的管理。并以此确定整个程序的时间管理。然后，本文介绍了单片机系统仿真软件的功能。它是以Windows为操作平台，利用VB6.0的可视化界面、事件驱动原理、各种控件及数据库编程知识，开发的仿真软件。经过编程及调试，基本上实现了主要的单片机实验的仿真。其中包括数据存储器、程序存储器、键盘的输入、数码管的输出、数/模转换器、模/数转换器、并行口、串行口等等的仿真。最后，在软件工程的指导下，介绍了软件的结构和设计过程论述了整个系统的程序设计思想和实现方法，编写了实现课题要求的软件及调试方法。 关键词 单片机，，，Abstract In recent years, along with the computer application technology development, the single chip microcomputer simulation technology has been improved a lot. It can realize the computer in general on the single chip microcomputer hardware modeling, simulation and instructions in the running state of simulation, the collection programming, modification, operation of the function in one body. Using single-chip microcomputer system simulation software can not only make full use of the rich resources of general machine improving the efficiency, but also, just click on the software development system part of program to make a little change, can upgrade to new single-chip microcomputer software development system to meet the requirements of teaching and engineering design. This topic is focused on hardware and users according to written assembly language, the operation process of the simulation system, and to realize the fixed circuit simulation. That is in SCP application systems hardware and software of the simulation of two parts. This paper first from discrete event systems simulation principle, through the comparison of the four simulation strategy, to determine the interaction process method to implement the simulation clock management. And so as to determine the entire program time management. Then, this paper introduces the function of SCM system simulation software. It is based on Windows for operating platform, the use of a vis
