Project analysis and modularization are realized by use of simulation software, each module is implemented by the combination of VHDL and principle figure, and the initial design of the chip is accomplished making use of hierarchy design methodology.

• 本文将层次化设计方法应用于芯片设计中，采用系统仿真软件进行方案分析和模块划分，并将各模块用硬件描述语言和原理图结合的方式来实现，完成了芯片的初步设计。
