基于FPGA的高速可变周期脉冲发生器的设计与实现

Design and realization of FPGA-based high-speed pulse generator with changeable period

基于FPGA高速、可编程的优点,设计了一款可以灵活改变脉冲输出周期和输出个数的周期脉冲发生器。利用VHDL语言编写了全部模块,并在Altera公司提供的QuartusⅡ4.1开发软件上实现了软仿真通过。经实际电路板验证,该实现方法符合设计初衷,达到设计要求。

A FPGA-based high-speed pulse generator,which has changeable period and the number of output pulses was developed.The pulse generator combines FPGA＇s advantages of being high-speed, programmable.All the modules are realized with Quartus Ⅱ4.1.Experiment results show that the solution can satisfy the design requirements.
