Infinite time for implementation

Jump to solution

Hi,

  I have got a design which keep routing forever.

 I attach a zip file containing the design, so that someone can try to replicate the issue.

  The design is basically an example design for 1G/10G/25G switching ethernet subsytem IP.

  Only pin constraints have been changed to adapt it to target ZCU102 board.

  I am using Vivado 2018.2.

Thanks for the files. I checked this is in same vivado version i.e 2018.2 and the implementation took ~2hrs to complete. From log file, I see the tool took more time to fix hold violation which could not be closed.

You need to review your constraints in the design.

The project which you shared has missing files. Can you share the archive project?

From Vivado GUI, select File-->Project-->Archive..  This will save your project in .zip file. Share this file.

Did you try running different implementation strategies? Also try disabling multithreading:

Which OS are you using? Make sure you use supported OS with Vivado 2018.2:

Hi @syedz,

  I cannot attach the archive since it is 25MB, even if I strip out the three include option.

  I am working on a Windows 10 64-bit machine.
