    Hi Kai

    Most common issues with failing Ellisys testing is because of a mismatch in VIF information with DUT.

    Can you do the following:

    • Verify that the VIF matches the capabilities of your DUT
    • Provide the VIF and prj file that you used for the TPS65986 testing
    • Provide the PD messages through a PD analyzer.
