基于LabVIEW和FPGA的多通道虚拟逻辑分析仪的设计

摘要

The design concept and theory of the virtual logic analyzer with multi -channels is discussed in this paper meanwhile, based on modularization virtual instrument technology, using FPGA as the basic hardware and Lab VIEW as the core software. It also describes the design of the hardware circuit and the method of data analysis and processing in software. It gives the actual signal test results in the end.%基于模块化虚拟仪器技术,阐述了一种以FPGA为硬件基础,以LabVIEW为软件核心的多通道虚拟逻辑分析仪的设计理念及实施方案.重点论述硬件电路设计和软件数据分析处理方法.最后给出虚拟逻辑分析仪的实测结果.
