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

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。

With the development of network communicationtechnology, Gigabit Ethernet has attracted wide attention because of its highreliability and fast transmission rate. Image acquisition and transmission havebecome an important development direction. This paper analyzes and tests the functionof 1000BASE-T image transmission system module, and uses UVM (universalverification methodology) to verify it to build a reusable verificationplatform. The reusability is reflected in the reuse from module level to systemlevel, the reuse of different test environments, the reuse between differentprojects, and so on. It is proposed that the function of the image transmissionsystem should be tested by regression. Finally, the effectiveness andcompleteness of the verification method can be determined by taking the resultof code coverage, function coverage and assertion coverage as the acceptancetarget of 100%.
