A10 DSP Core Timing Error

Hi All,

I have a problem about Arria10 Chip MPDSP Core in my design. A path from register to MPDSP's ax[30] pin timing violate,

Then I used TimeQuest Timing Analyzer report this path and found that MPDSP's ax[30] pin setup time(uTsu)=2.955 ns.

Why this uTsu so long ?

The Timing analysis as post picture!

    Hi,

    Can you locate the ax[30], or the path including launched from ax[30] in Technology map viewer?

    You can do right-click on the cell of the Time Quest table, and select the Locate-path -> Technology map viewer.

    I would like to know what resources is the path mapped to on the chip.
