摘要

在第五代移动通信技术（5G）通信中，动态带宽分配（DBA）作为无源光网络的关键技术之一，随着其不断优化自身性能，芯片功能的复杂度日益增长，对其逻辑功能的验证显得尤为重要。文章提出了一种无源光网络中的DBA模块验证平台架构体系。该平台基于通用验证方法学（UVM）框架调用System Verilog（SV）参考模型，以少数用例覆盖大量场景，实现了对DBA流量需求和下发授权功能点的验证和结果自校验，寄存器转换级电路（RTL）代码覆盖率可达95%以上。仿真表明，该验证平台支持DBA的系统级验证，支持框架复用和自动化数据对比，可满足验证的各项需求，为DBA的性能测试提供了一个高效和全面的验证环境，大大提升了验证效率。

Abstract

In the era of 5

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.
