基于LabVIEW和FPGA的数字电路板比对测试系统设计

摘要

A comparison and test system of digital circuit board was designed based on the LabVIEW and FPGA.The system produced the excitation signals by use of FPGA,and the signals were measured by means of the high speed sampling and cache.At the same time,with the help of LabVIEW software in the upper monitor,the whole system control,comparison and analysis of the measured signals were per-formed.The actual study showed that this system is stable,reliable in running and easy to operate,it can provide the basis for the troubleshooting of the digital circuit.%设计了一种基于 LabVIEW和 FPGA的数字电路板比对测试系统，该系统利用 FPGA 产生激励信号并对被测信号进行高速采样及缓存，同时借助于上位机的 LabVIEW软件完成对整个系统的控制和被测信号的比对分析。实际应用表明，该系统具有运行稳定可靠、操作方便等特点，为数字电路的故障排除提供了依据。
