对大量已存在的数字系统,提出采用VHDL语言对其进行直接描述的方法,并以电风扇控制系统的VHDL程序设计为例对此方法进行探讨,实例经过编译和仿真得出了正确结果,充分表明了该方法的可行性。
For a large number of existing digital systems, this paper presents a method of using VHDL language to describe them directly. The VHDL programming of the fan control system is taken as an example to discuss this method. After compiling and simulating the examples, the correct results are obtained. The feasibility of this method is demonstrated.
