摘要
介绍以AlteraCPLD系列FLEX10K器件为虚拟载体,在Windows95/98下借助Delphi5.0实现人机交互界面,借助PC机的控制离线完成对常用TTL74和54系列、CMOS4000和4500系列、常用RAM、EPROM、部分CPU接口芯片的故障检测的VHDL设计原理和实现方法。
In this paper,we introduce a testing instrument,which used the Altera CPLD FLEX10K device as the virtual carrier controlled by PC.By means of Delphi 5.0in Win-dows95/98,we can qualitatively test the malfunction of many kinds of chips away from the system such as the series of TTL74and TTL54,CMOS4000and CMOS4500,RAM,E-PROM,the some interface chips of CPU etc.The instruments' VHDL design principle and realizing method are also given.
