Research on Reconfigurable Instruments Based on FPGA
Shaohui Cui, Mingze Gou, Jin Luo · 2016
It is incidental for current automatic test system (ATS) to lead short of circuits, damage of instruments or units under test (UUT) by reason of its large amount of switches.To solve the problem, the technique of reconfigurable instrument is introduced.Using the reconfigurable instruments as substitutes for variety of single function instruments, the ATS reduces the number of switches, cuts down the redundancy of instruments and interfaces, improves reliability.By employing AP configuration mode, a FPGA partial reconfiguration scheme based on FLASH + SD card is introduced in this paper.The FPGA reconfiguration technology is analyzed and corresponding configuration SOPC system is designed.The reconfigurable instrument functions are realized combining the reconfigurable FPGA and universal peripheral circuits.
