基于UVM的1000BASE-T图像传输系统的验证

Verification of 1000BASE-T Image Transmission System Based on UVM

摘要: 随着网络通信技术的发展，千兆以太网凭借可靠性高且传输速率快等特点，从而受到广泛的关注。图像的采集和传输也随之成为重要的发展方向，本文对1000BASE-T图像传输系统模块的功能进行分析和测试，并采用UVM (Universal Verification Methodology)通用验证方法学进行验证，搭建一个可重用性的验证平台，可重用性体现在从模块级到系统级的重用、不同测试环境的重用、不同项目之间的重用等。提出对图像传输系统的功能进行回归测试，最终以代码覆盖率、功能覆盖率、断言覆盖率结果达到100%为验收目标，即可确定该验证方法的有效性和完备性。

Abstract: With the development of network communication technology, Gigabit Ethernet has attracted wide attention because of its high reliability and fast transmission rate. Image acquisition and transmission have become an important development direction. This paper analyzes and tests the function of 1000BASE-T image transmission system module, and uses UVM (universal verification methodology) to verify it to build a reusable verification platform. The reusability is reflected in the reuse from module level to system level, the reuse of different test environments, the reuse between different projects, and so on. It is proposed that the function of the image transmission system should be tested by regression. Finally, the effectiveness and completeness of the verification method can be determined by taking the result of code coverage, function coverage and assertion coverage as the acceptance target of 100%.
