摘要:
事务层协议处理模块是 1394 总线某款在研网络通信 SoC 芯片的核心器件,负责总线各节点上层应用软件与链路层之间读、写请求和锁定请求关键事务通信。 为有效模拟软硬件在宿主机芯片上工作交互的复杂场景,该文从分析事物层系统级功能分析出发,重点研究芯片内部软硬件激励程序的执行效率和软硬件验证程序运行过程所占的比重,提出一种基于 UVM 的 1394 总线事务层系统级功能验证方案,给出了该方案的虚拟验证策略与方法,包括虚拟验证平台组件、工作原理和平台架构设计,并对其中关键验证组件进行详细介绍。 最后,通过仿真验证和收集覆盖率分析,该方案不仅有效满足事务层系统级验证总体需求,灵活完成 1394 协议解析,还可以为今后 1394 总线相关 SoC、ASIC 设计提供通用虚拟验证平台.
Abstract:
The transaction layer protocol processing module is the core device of a network communication SoC chip under development in 1394 bus,which is responsible for the key transaction communication of read,write and lock requests between the application software on the upper layer of each node and the link layer. In order to effectively simulate the complex scenarios of software and hard ware interaction on the host chip,starting from the system-level functional analysis of the transaction layer, the execution efficiency of the hardware and software driver and the proportion of the running process of the software and hardware verification program in the chip are emphatically studied. A system-level function verification scheme of 1394 bus transaction layer based on UVM is proposed,and the virtual verification strategy and method of the scheme are given, including the virtual verification platform components,working principle and platform architecture design,and the key verification components are introduced in detail. Finally,through simulation verification and collection coverage analysis,the proposed scheme can not only effectively meet the requirements of system - level verification at the transaction layer,flexibly completes 1394 protocol analysis,but also provide a common virtual verification platform for future 1394 -related SoC and ASIC designs.
