基于FPGA的小数分频器设计

Design of Decimal Frequency Divider Based on FPGA

在数字系统设计过程中,经常涉及小数分频器。阐述在中国知网对基于FPGA分频器设计进行检索,采用Citespace软件对其关键词进行可视化分析,汇总FPGA小数分频器设计的三种方法,分别在QuestaSim软件中完成仿真验证,并给出仿真波形,结合三种方法完成小数分频器的设计。

In the design of digital system,frequency divider is often involved.This paper firstly retrieves related researches on the design of frequency divider based on FPGA on CNKI and makes the visual analysis of its keywords by Citespace software,then it discusses three methods of decimal frequency divider based on FPGA design,completes simulation in Questa Sim software respectively,gives the simulation waveforms,and completes the comprehensive design of decimal frequency divider by combining the three methods.
