摘要
随着FPGA在各种工业应用越来越广泛,FPGA重构技术在快速的FPGA自动测试中应用越来越广泛。传统的基于JTAG方式和基于配置芯片的FPGA重构方案由于存储配置时间长,配置芯片成本高等原因越来越满足不了快速的多重配置需求。提出了一种基于大容量FLASH存储器的FPGA重构技术,方案采用FPGA作为主控制器,大容量FLASH芯片用于存储目标FPGA的配置数据,可以实现绝大部分不同型号的FPGA器件的快速多重重构,从而满足FPGA芯片快速自动测试需求,提高了整体程序开发和测试效率,节约了芯片的测试成本。
Reconfigurable technology of field programmable gate array （FPGA） is used more and more in FPGA fast and auto testing. Conventional FPGA reconfigurable technology based on configurable PROM can not meet the requirement of fast and multi reconfiguration. A new FPGA configuration technology is put forward, in which FPGA is used as controller and one big capacity flash is used to storage configuration data. This technology can be used to most FPGA devices of Xilinx, which solves abuse of the last configuration ways and makes FPGA fast and auto testing more efficient.
