【摘要】：高性能同轴电缆接入网(High performance Network Over Coax,HINOC)技术是在国家加速推进三网融合的政策背景下,为实现下一代广播电视网的基础目标,由我国提出的具有自主知识产权的新型EoC(Ethernet over Coax)技术。由于市场对网络带宽需求的快速增长,最高支持1 Gbps物理层传输速率的HINOC 2.0技术方案被提出。同时,HINOC 2.0样机和系统级芯片(SoC)的研发也已经逐步展开。随着研究的深入,需要对HINOC 2.0芯片的设计进行验证,以全面高效地保证设计实现的正确性。其中,HINOC系统链路层核心模块HIMAC的功能验证是整个验证工作的重要组成部分,对于后续系统级验证和保障芯片成功投产有着重要的意义。本文工作围绕HIMAC模块的功能验证展开,主要贡献在于结合通用验证方法学(Universal Verification Methodology,UVM)提出了一种对HIMAC模块进行功能验证的新方法,设计实现了该模块的验证平台并验证了组帧、拆帧相关功能。首先,对UVM的设计思想和实现机制进行深入研究。其次,分析HIMAC模块的主要功能和外部接口,并在此基础上提出了验证HIMAC模块组帧、拆帧功能的具体方案。再次,基于UVM设计验证所需各种组件并完成了模块验证平台的构建。最后,结合模块功能特性设计了具体的测试用例,并对模块的组帧、拆帧相关功能进行了验证。验证结果表明,本文所提出的验证平台可重用性强、自动化程度高、层次清晰,实现了对相关功能点的有效验证,达到了预期的要求,为HIMAC模块更加全面的验证打下了良好的基础,也为后续系统级验证提供了参考。
[Abstract]:High performance coaxial cable access network (High performance Network Over Coax HINOC) technology is accelerating convergence under the background of national policy, to achieve the basic goal of the next generation of broadcast television network, the new EoC with independent intellectual property rights proposed by China (Ethernet over Coax) technology. Due to the rapid growth of the market the demand of network bandwidth, supports up to 1 Gbps physical layer transmission rate of HINOC 2 was introduced. At the same time, the HINOC 2 prototype and system on chip (SoC) development has gradually expanded. With the in-depth study, to design of HINOC 2 chip to verify, to fully and efficiently guarantee the correctness of design and implementation the link layer HINOC system. Among them, the core module of HIMAC functional verification is an important part of the verification work, for subsequent system level verification and guarantee the successful operation of the chip is important The significance of this paper focus on functional verification. The HIMAC module, the main contribution is to combine the universal verification methodology (Universal Verification, Methodology, UVM) puts forward a new method to verify the function of the HIMAC module, the design and implementation of the module of the verification platform and verify the frame, frame remove related functions. First, in-depth study the design idea and Realization Mechanism of UVM. Secondly, analysis the main functions and the external interface of the HIMAC module, and on the basis of the verification of the HIMAC module frame, concrete scheme frame remove function. Thirdly, based on the UVM design verification required for various components and complete the construction of module verification platform. Finally, the specific test case design with function characteristics, and the module frame, frame remove related functions are verified. The verification results show that the proposed verification platform strong reusability, since The degree of mobility is high, and the level is clear. It achieves effective verification of relevant functional points, and achieves the expected requirements. It lays a good foundation for HIMAC module's more comprehensive verification, and provides a reference for subsequent system level verification.
