VHDL在导弹控制系统中的应用

研究利用超高速集成电路硬件描述语言（VHDL）设计某导弹数字控制器中硬件控制器的方法，结合EDA设计思想对该系统的硬件控制器进行总体功能和各子功能的分析、设计，然后利用VHDL对各功能模块进行描述，最后将已经过仿真检验的设计卸载到相应的可除编辑逻辑器件（EPLD）中，充分利用VHDL的灵活性、可移植性和可编程逻辑器件的静态可重复编程及在线动态重构特性，使硬件设计像软件一样通过编程实现，半实物仿真试验结果表明，硬件控制器性能稳定，满足了设计要求。

Application of VHDL in the Control System of Missiles

A method of hardware control for a missile controller system designed by VHDL is studied. Combined with the design principle of EDA, the functions of the whole system and subsystems were designed and analyzed. The function of each module was then described by VHDL. At last the final design was tested through simulation and was downloaded to the relevant EPLD. In this paper, the flexibility of VHDL and the characteristic of reprogramming in the static state and programming in the dynamic state for programmable logic were well made use of, which allowed the hardware to be designed by programming just like the software. Through results of the hardware in the loop simulation system, it was shown that the performance of the hardware controller was stable, and the design requests satisfied.
