A new method for FPGA development

System Generator is a system level DSP development tool developed by Xilinx Company, which is based on the graphic modeling technology of Simulink, also is an FPGA-based signal processing modeling and design tool. This paper proposes an FPGA development method based on System Generator. Firstly it analyzes the insufficiency of traditional FPGA design flow, and then studies the advantage in FPGA development based on System Generator. The paper designs a digital beam forming system by means of System Generator. The experimental result indicates that System Generator has an apparent advantage in FPGA design.
