A10 DSP Core Timing Error

[Altera_Forum]

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!  pofeng1885 shenh@innorise.cn

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.  Mickycat
