    Hi Adithiya_R,

    Thanks for sharing your observation.


    This is an expected behavior. The TLP header and data are dword aligned. There is no workaround to change the address alignment that I am aware of.

    Thanks.

    Best Regards,

    Ven

Hi Adithiya_R,

Thank you for confirming the answer provided.


Could you please create a new forum post about the new inquiries on the clock and timing analysis?

We prefer to have separate issues or inquiries filed for each distinct support issue to ensure better tracking and resolution.


Since the initial inquiries on the P-Tile AVST BAR have been addressed, I will transition this forum to community support.


Thank you for your understanding.


Thanks.

Best Regards,

Ven
