摘　　要：介绍了应用电子电路设计自动化 (EDA)工具 MAX+plus II进行的数字电路设计 .所探讨的主要内容是 EDA设计方法和硬件描述语言VHDL的使用 ,并以 82 55为实例进行了编程和仿真 .将经过仿真检验的设计卸载到相应的可擦除编程逻辑器件 (EPL D)中 ,充分利用了 VHDL 的灵活性 ,可移植性和可编程逻辑器件的静态可重复编程特性 ,使硬件设计像软件一样通过编程实现 .半实物仿真试验结果表明满足了设计要求 .This paper introduces designing digital circuits by using MAX+PLUS II ,which is the application ware of electronic design automation (EDA) tools. The main contents are the application of the method of EDA and the usage of hardware description language-VHDL. Programming and simulating are carried out by taking 8255 as an example. At last, the final design is tested through simulation and is downloaded to the relevant EPLD. The flexibility and portability of VHDL and the characteristic of reprogramming in the static state are discussed allowing the hardware design to be programmed like the software. Through results of the simulation, it was shown that the performance of the hardware controller is stable and satisfied.
