Regarding Power-Up Sequence for Agilex 5

Regarding the power sequencing of Agilex 5, the required power-up sequence is specified in the documentation. However, in our case, the sequence was not properly followed.

Could you please advise what kind of impact may occur on the FPGA if voltages are applied under such a condition where the specified power sequence is not met?

    Thank you for your reply,

    Even when operating within the Absolute Maximum Ratings, is there a possibility that a short circuit could occur if power is applied without following the power sequencing or under conditions that do not meet the Recommended Operating Conditions?

    Hello, 

     

    For Agilex 5 devices, power up sequence is a must to follow to make sure the FPGA power up successfully. 

    The impact could be functional error in user mode or worst- unable to power up.
