Design of Virtual Logic Analyzer Based on PC

Logic Analyzer is used for testing the digital information in the digital system,whose structure is complex and the cost is higher.Introduced the designing ideas and methods of Virtual Logic Analyzer based on the conception of Virtual Instrument.The circuit of hardware was simplified,because the partial function of hardware was intenerated.In this way,it lowered the cost of the instrument and improved the reliability and performance of the Logic Analyzer.Mainly expatiated the design of the hardware circuit and the software in the Virtual Logic Analyzer based on PC.
