| Summary: | In the era of 5<sup>th</sup> Generation Mobile Communication Technology (5G) communication, hardware products such as optical modems and routers are updated iteratively. As one of the key technologies of passive optical network, Dynamic Bandwidth Allocation (DBA) constantly optimizes its own performance. The functional complexity of the chip is increasing, and the verification of its logic function is particularly important. This paper presents an architecture of DBA module verification platform in passive optical networks. Based on the verification methodology framework of Universal Verification Methodology (UVM), the platform calls the System Verilog (SV) reference model. It can cover a large number of scenarios with a few test cases, and realize the verification and self checking of DBA traffic requirements and authorized function points. The coverage rate of Register Transfer Level (RTL) code can reach more than 95%. The simulation results shows that the verification platform can support the system level verification of DBA, and the framework reusing and automatic data comparison. The proposed architecture can meet the requirements of verification, and provide an efficient and comprehensive verification environment for the performance test of DBA, and greatly improve the verification efficiency.
