    Hi ArjunTechM,


    Which compilation stage that this error occurred?


    If possible, may I know on how the error can be replicated?

    Are you already attached the code? Because I cannot see it in this thread.


    Regards,

    Adzim

    Hi Arjun,


    Thank you for sharing your feedback and the code.


    I will try to replicate the issue from my side and check the design.

    Hi Arjun,


    I have checked your design that you have attached.

    I cannot reproduce the error that you have stated in previous comment but can see other error.


    In this design, the alert pin is set to output port which is causing the error.

    Change the alert pin port to input will resolve the error.

    The change can be made in top level file at line 159.

    Then you should be able to compile the design.


    Please let me know if the issue still not resolve.


    Regards,

    Adzim
