摘要
Abstract
High Definition Multimedia Interface(HDMI)technology is widely used in daily life.Therefore,the functional verification of the HDMI-CEC(Consumer Electronics Control)interface has become increasingly important.This paper designs and implements a verification platform for the HDMI-CEC interface based on the Universal Verification Methodology(UVM).The platform is capable of generating constrained random test excitations through its modular design.The functional coverage and code coverage are used to evalu-ate the completeness of verification.In this study,the automated testing process and coverage-driven verification strategy provided by UVM are employed,resulting in a significant improvement in verification efficiency and accuracy compared to traditional methods.The core components of the verification platform are extended through UVM's standardized class library,ensuring the platform's reusability,scalability,and maintainability.The verification results show that the verification platform can effectively cover the various function points of the HDMI-CEC interface,so that the function coverage and code coverage are 100％,verify the validity and stability of the design.The research results provide an efficient and reliable solution for the verification of HDMI-CEC interface,highlighting its sig-nificant value in practical engineering applications.关键词
