【摘要】 介绍了用VHDL语言设计七段显示译码器的原理和方法,给出了VHDL原码驱动程序和正确仿真结果的时序图.这种设计方法的优点就是使用综合工具对电路整体结构先进行组合优化、编译,删繁取真,再利用仿真工具对其进行波形仿真,检验电路的正确性和可靠性.通过这样的设计方式,设计人员无需多长时间,就能设计出性能稳定、运行可靠、满足实际需求的优质电路.更多还原

【Abstract】 Principle and method of design for seven display decoder are introduced in VHDL language,the VHDL source code and correct results of simulation sequence diagram are given,and it shows that the advantages of this method is using comprehensive tools to make combinatorial optimization,compilation to circuit integral structure,and deleting numerousness to take true,then the simulation tool of the waveform is used to test circuit so as correctness and reliability are obtained.With the design way,the design personnel need not long time to design a stable performance,operation on that,meeting the actual demand of high quality circuit,which promote the electronic device to develop faster and better.更多还原
