    Who writes the test cases in IC design?

    I guess test case means a particular test which has defines the certain inputs and expected outputs?

    Can you define test case more properly for a novice?
    And I'm also wondering who writes the test cases for ICs? Verification engineers or test engineers?

    that is correct
    however, most things need several test cases to check functionality
    programmable devices need a LOT of test cases
    it is also unlikely that one can test every possibility in a big programmable device.

    i think you defined it sufficiently well
    as for who writes the test cases, verification and test have to work together
    there may not specific people assigned these tasks, both of which need to start when the project starts

    testing is more demanding than designing

    Hi,

    Maybe you can get some clue by reading a datasheet of a comparable IC.
    It tells you the test conditions, maybe even a test circuit ... and the limits.

    Re: Who writes the test cases in IC design?

    The designer would / should have "tested" the design to
    all of the datasheet electrical performance table line items.
    This would / should populate a test requirements document
    in an orderly product development flow. The TE would
    develop the test platform implementation (and perhaps
    supplemental resources, like bench jigs and support) with
    the DE as a resource and the PE (product engineer) as the
    "customer" (saying when complete and credible, etc.).

    Over-the-transom verification and test development does
    not often work well. The test engineer only knows what
    to apply and expect, when someone or something tells
    them. And chip designers may be insulated from "big
    iron" tester, harness, load board practicalities requiring
    some thought about methods, different than as-simulated.
