一种数字波束合成芯片的FPGA验证系统搭建OA

The digital beamforming(DBF)chip is a kind of complex application-specific integrated circuit(ASIC)chip,and its verification work before tape-out is crucial to improve the success rate of the chip.A field programmable gate array(FPGA)-based prototyping verification system construction method is proposed.The Quad VU verification board from S2C Technology and a Raspberry Pi development board are employed to simulate the application scenario after tape-out.By reasonably trimming the chip design code,replacing the non-compilable modules for the FPGA,and redesigning the clock architecture,the functional verification of the DBF chip on the FPGA is realized.The experimental results show that the system can effectively verify the data processing flow and multi-chip cascade function of the chip,which lays a solid foundation for chip post-silicon test.
