Design of universal test instrument based on FPGA reconfigurable technology

摘要

Based on FPGA reconfigurable technology, this research analyzes and compares several ways of realizing FPGA reconfiguration and proposes a plan of reconfigurable design based on SOPC. In this plan, the structure of "FPGA + Flash + SD Card" is adopted, and the universal test instrument is designed to incorporate multiple functions such as signal excitation, signal acquisition, data communications, and fault diagnosis and so on. It has many advantages of miniaturization, universalization, being reconfigurable, being easy to upgrade and supporting the parallel test.
