At present, it is the first class in the world that the design of digital system and single chip system using CPLD. In this design, with the EPM7096QC100-7 EPM7032LC44-6 (CPLD device made by ALTERA company)as CPU and other outside corresponding device to produce a timer showed by the digital diodes. Take the EPM7032LC44-6 for example, take the structure 、function、language VHDL and programming of it’s procedure to elaborate CPLD’s Convenience and vividness. Above of all, based on elaborating the usage blemish of MCU ,we can find the usage advantage of CPLD/FPGA in the future. Key words EDA、FPGA、CPLD、VHDL、MaxplusⅡ、in syetem programmable、simulater、countdown 目 录
