VHDL作为一种新型的硬件描述语言,主要用于数字电路与系统的描述、模拟和自动设计,是当今电子设计自动化(EDA)的核心技术。文章通过十六位计数器的实例介绍了用VHDL语言设计数字系统的流程和方法,并通过仿真实现预定目的。实践证明,VHDL语言在数字系统设计中具有硬件描述能力强,设计方法灵活等优点,从而降低了数字系统设计的难度,提高了工作效率。
As a new hardware description language, VHDL is mainly used in the description, simulation and automatic design of digital circuits and systems. It is the core technology of electronic design automation (EDA) today. The article introduces the process and method of designing digital system in VHDL by the example of sixteen counters, and achieves the intended purpose through simulation. Practice has proved that, VHDL language in the digital system design with hardware description ability, design flexibility and other advantages, thereby reducing the number of digital system design and improve work efficiency.
