PCM30/32路基群帧同步电路的VHDL设计

Design with VHDL of PCM30/32 Basic Group's Frame Synchronous Circuit

帧同步电路是数字通信系统中的重要组成部分。文章在分析PCM30/32路基群帧结构和帧同步电路结构及功能的基础上,以EDA仿真软件Modelsim SE5.6为开发平台,采取自顶向下的现代电子设计方法,进行了帧同步电路的VHDL设计。通过仿真测试,所设计电路完全满足通信功能要求,并可以利用HDL逻辑综合软件LeonadoSpectrum将设计文件翻译成逻辑电路。

Frame synchronous circuit is an important component of digital communication system. Based on the analysis to PCM30/32 basic group＇s frame structure and the structure and function of frame synchronous circuit,the chapter has designed with VHDL the frame synchronous circuit with up - down method of modern electronic designing by using EDA simunation software Modelsim SE 5.6 as developing platform. Simunation testing has shown that the circuit designed can fully meet the needs of communication function, and with HDL logic synthesizing software LeonadoSpectrum the file designed can be translated into logic circuit.
