硬件描述语言VHDL在数字系统设计中的应用

Application of hardware description language VHDL in the digital system design

VHDL语言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.文章通过四位乘法器的实例详细介绍了用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.结果表明,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,从而大大降低了数字系统设计的难度,提高了工作效率.

VHDL, as a new type of hardware description language, is used to describe, simulate and automatically design digital system. Nowadays, it beeomes a key technology in electronic design automatic （EDA） . The method and process using VHDL to design digital system is presented through an example of multiplier design. The anticipative target is achieved through simulation. The result shows that VHDL is strong in hardware description and flexible in design method. It could reduce the design difficulty of digital system and improve efficiency.
