FPGA (field programmable gate array) removable high-speed operation verification development board

Abstract

The invention discloses an FPGA removable high-speed operation verification development board. The FPGA removable high-speed operation verification development board comprises a development board body, a socket arranged on the development board body, and an FPGA chip detachably connected to the socket. The development board body is provided with a bonding pad corresponding to the encapsulation mode of the socket, and the socket is welded to the bonding pad; the socket is provided with base pins corresponding to the solder ball of the FPGA chip, the upper ends of the base pins are connected with the solder ball of the FPGA chip, and the lower ends of the base pins are connected with wires on the development board body; the FPGA chip is electrically connected with elements on the development board body through the base pins of the socket; for matching with the characteristic of high operating speed of the FPGA chip, high speed data storages including a Flash chip, a FRAM (flash random-access memory) chip and a DDR (double data rate 3) chip are arranged around the FPGA chip, and the chips can be called separately as well as simultaneously to ensure high-speed operation of the development board body. The FPGA chip can be manually mounted and removed on the development board without other equipment, thereby being convenient to remove, avoiding damage and achieving mounting and removing repeatability; meanwhile, the FPGA removable high-speed operation verification development board gives full play to the advantage of the FPGA which can parallel-process data, thereby fully meeting the requirements of design verification.
