文章采用VHDL语言设计了数控分频器电路,利用数控分频的原理,设计了乐曲演奏电路,并采用原理图方法设计了数字时钟,该电路具有校时校分的功能,用MAX_PLUSⅡ编程工具进行逻辑综合和时序仿真,经下载到EPF10K10芯片上验证,达到了预定的效果。与传统的纯硬件方法相比简单有效。
In this paper, the design of a digital control circuit using VHDL language, the use of numerical control principle, designed the music playing circuit, and the use of schematic diagram of the design of the digital clock, the school has the function of school hours, with MAX_PLUS Ⅱ programming tools Logic synthesis and timing simulation, downloaded to the EPF10K10 chip verification, to achieve the desired results. Compared with the traditional pure hardware method is simple and effective.
