This paper presents a framework for complete simulation and verification of Serial Digital Interface (SDI) video using a verilog test-bench and geared toward FPGAs. This framework permits simulating the entire process: from test video signal generation to protocol verification in the FPGA which implements the Device Under Test (DUT). The novelty in the design is the combination of a customized test video signal generator with an implementation clone of DUT transceiver for in-depth protocol debugging. Identical input test patterns of the video protocol under test are generated and fed to DUT for verification. Thus, the model not only permits to evaluate the SDI transport layer but also validates the implementation at ultra low pixel level of the video format. This approach provides two advantages: cost saving in terms of additional lab test equipment and delivering all-in-one test solution to verify design and implementation. A practical implementation using a test example of a macroblock processing chain using SDI video interface shows the viability of the proposed framework for video protocol testing.
