基于UVM 和ZeBu 的DVB-RCS2标准Turbo译码验证平台

A DVB-RCS2 Turbo Decoder Verification Platform based on UVM and ZeBu-Server

本文提出了一种适用于DVB-RCS2标准提出的Turbo译码模块的验证平台。该平台基于UVM(Universal Verification Methodology)验证方法学,通过调用C参考模型,实现译码结果自动化比对并统计误包率,省略了用硬件语言编写参考模型的时间。同时,该平台集成了ZeBu硬件加速器,可选择性打开或关闭ZeBu开关。通过仿真验证比较,打开Zebu的仿真速度比关闭Zebu仿真速度提升了35倍,大大提升了仿真验证效率。

This paper introduces the verification platform of Turbo Decoder module which is suitable for DVB-RCS2 standard.The platform is based on UVM(Universal Verification Methodology),it can automatically compare the decoded result and realize packet error rate through importing c reference model which can save time of encoding reference model with hardware language.In the same time,the platform integrates ZeBu-Server which can be chose to open or close.The results of verification show that the simulation speed with ZeBu on is increased by 32.5 times.The proposed design has promoted verification efficiency significantly.
