摘　　要：ispPAC的出现使得模拟电路设计中在信号的调理、信号处理及信号的转换方面可采用图形结构语言实现计算机编程设计,此外软件的仿真功能,更使得对设计结果验证具有直观性和便捷性,大大减化了许多模拟电路设计和检测中费时费力的工作。但是,结果的仿真,是计算机对理想电路特性的模拟,同具体电路的实际情况究竟存在多大差距?由于在厂家提供的资料和相关文献中未见报道,作者就此问题进行了探讨。The appearance of ispPAC in the analog circuit design causes the realization of the computer programming design to deal with the signal recuperation, the signal processing and the signal transformation by using the graphic construction language, in addition, the function of software simulation make it vivid and convenient to test the design result, greatly reduced the heavy and time-consuming work which exist in many analog circuits design and the examination. But, the result of the simulation is the computer simulation to the ideal electric circuit characteristic, it inevitably has the disparity with the actual situation of the concrete electric circuit. But the extent of disparity between the computer simulation and the actual circuit didn＇t report in the materials provided by the factories and the relative literatures. The author discusses the question in this paper.
