摘　　要：随着数字电子技术的发展,传统的数字电路设计方法已不能满足现代数字集成电路系统设计要求,借助硬件描述语言完成硬件设计成为电子设计的趋势。通过介绍VHDL硬件描述语言的基本结构、基本特点和设计流程,以全加器为例说明用VHDL语言设计数字逻辑电路的方法,并给出了仿真结果。结果表明,VHDL对数字电路的硬件描述能力强,在设计上非常有效,是数字电路教学中全新的理论联系实际的方法和培养学生实际动手能力的有效工具。With the development of digital electronic technology,the traditional design methods of digital circuit can＇t meet the needs of the digital integrated circuit.It has been a developing trend to accomplish the design of hardware circuit by VHDL.A brief introduction of the basic structure,features and the design process of VHDL is given.The full adder is used as an example to illuminate the designing method of what is applied to the design of digital circuit,and the simulate result is achieved.As the result suggested,VHDL,which is powerful to depict the hardware of digital circuit and effective in design,is a useful tool to combine theory with practice in teaching digital circuit and cultivate the students＇ performing ability.
