基于FPGA窄脉冲信号发生器的设计
Design of Narrow Pulse Signal Generator Based on FPGA
摘要
Abstract
To address the problem of low capture efficiency of electron induction accelerator,considering that the pulse current signal generated by the electronic circuit method acting on the capture coil will cause temperature changes,electromagnetic interference,etc.A programmable narrow pulse signal generator is designed based on FPGA.Through modular design,it can output specific and stable pulse waveforms that meet requirements,the period of this pulse waveform is 300µs,the pulse width is about 3µs,the rising part of the waveform is an exponential curve,very fast response time,the descending part decays linearly.Using serial communication,the waveform data that meets the requirements(saved in TXT file format)can be written into the EEPROM of the FPGA at one time.This first ensures that data will not be lost after power failure,then reads and writes from EEPROM to RAM,finally,reads the waveform data from RAM.The results show that using MODESIM simulation,the simulation results are basically consistent with the on-board verification process,and the target waveform can be output well,verifying the feasibility of the pulse signal generator.关键词
