    hd-sdi interface testing

    Hi everyone
    I need to test a design which has Xilinx SMPTE SDI Core which had HD-SDI interface..... It goes to rest of the components....

    I am not conversant with it.

    I have been asked to mimic that interface in my testbench and use the signals coming out of it as an input to test other components in the design.

    I have not done that before. What does this mean and how do I mimic this interface and use it signals to test other components to the design to which it is connected to...

    If anyone can tell me how do I do that please


    Many thanks for your help

    Re: hd-sdi interface testing

    It means you're being asked to create an SDI signal over the interface as a behavioral model. This way you can test your blocks without using the Xilinx IP in the testbench.
    I assume you know what the output of the Xilinx SDI core should look like?

    You're essentially asked to build a BFM - Behavioral Functional Model.
    Think of it as if you were given a task to design the far end side of the SDI...
    But with one major waver - you're not constricted to writing purely synthesize code. This will allow you to use language contracts that are un-synthesizable but are functionally correct.

    Re: hd-sdi interface testing

    Sure.
    There 3 important steps:
    1. Read the SDI specification and understand how it works.
    2. Write the code.
    3. Test the code.

    Re: hd-sdi interface testing

    Thanks for your reply.

    I would appreciate if you can point me to some reference bus functional model (if not particularly this) one so that I can get some idea of making those.

    Many thanks

    Have you read the spec? Yes or no.

    Honestly. Not completely and carefully as yet( Just a glance yet)
