Abstract

The present disclosure discloses a programmable digital I / O system for a PXI bus based on an FPGA and an implementation method thereof. The system and the method dynamically configure a digital I / O interface according to test requirements based on the reconfigurable function of the FPGA, so as to realize the switching of the rate, level, transmission protocol, and transmission direction of a datatransmission, so that the system and the method are more flexible and versatile. The same digital I / O module is used to implement a variety of standard digital test and control functions, so that thedefects of the operation complexity and the impact on the real-time of the data caused by restarting a computer when function modules are switched are avoided, and the research and development cost issaved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic measurement and testing, in particular to an FPGA-based PXI bus programmable digital I / O system and an implementation method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Digital I / O (input and output) modules are widely used in fields such as industrial control and automatic testing. The prior art is designed for specific application occasions and has poor flexibility. At present, there are many types of input / output interface modules of digital quantities in test and control instruments. The speed, level, power, and direction required for different applications are often different. Dedicated digital I / O modules will use dedicated level protocols and communication protocols to implement dedicated measurement and control functions for specific ...
