摘要
高清晰度多媒体接口(HDMI)在数字多媒体领域中被广泛应用,由于其传输速度快,传统ATE无法直接测试。为此设计了一种针对HDMI的高速测试方法,开发了以芯片解码和同步校验为核心的功能测试模块,该模块可实现对HDMI传输数据的控制、分析、通信与监测。将模块嵌入到具备VXI总线的集成电路测试系统中,可实现较完整的功能和直流参数测试。测试实验提示,本方法稳定可靠,测试效率高。
HDMI is widely used in the field of digital multimedia, limited to its high speed transmission characteristics, it can＇t be tested by the traditional ATE directly. We design a HDMI test method and develop a functional test module to decode chip and synchronous calibration as the core, the module can realize the control and analysis, signal communication and monitoring mechanism. By embedded into the integrated circuit test system with VXI bus, the function and DC parameters test can be realized relatively complete. The test results indicate that this method is stable and reliable, the test efficiency is high.
