UVM-based phased array radar digital beam former module verification method and verification platform thereof

Abstract

The invention relates to a UVM-based phased array radar digital beam former module verification method and a verification platform thereof. The verification method constructs a C function model in an excitation generator module by use of a DPI, realizes complex number operation of channel data, weight coefficients, correction coefficients and wave beam directional coefficients and completes conversion from floating numbers to fixed-point numbers for exciting into a DBF module. At the same time, the verification platform automatically acquires wave beam information after operation of the DBF module and performs automatic result comparison with a reference module, and correctly compared results are converted from the fixed-point numbers into floating numbers and then are written into files for subsequent processing. The advantages are as follows: reuse is realized, the maintenance is easy, the efficiency is high, the coverage is high, the code amount of the verification program of the DBF module and the workload of later board debugging can be greatly reduced, and the development efficiency and the quality of FPGA logic codes of the DBF module are improved.

AI Technical Summary

Problems solved by technology

However, with the increase of DBF system scale and design complexity, a lot of time will be wasted only by post-board debugging, and it is difficult to locate logic errors, and it cannot be guaranteed that the designed modules have been fully verified, and there will be no errors under boundary conditions
