how to dump routing elements in Quartus II

Is there a way in Quartus II to dump out the routing resources of a device

using TCL? I am interested in STRATIX V.

I know how to dump out routing resources of a used design using routing_path,

but that gives you used connectivity and not "available connectivity".

thanks.

    Doubtful. I've never seen it done nor heard of it. Why do you want this? I believe the Altera University Program does stuff with people who want to work with "routing", but it's purely for academic purposes. I hope you're not hand-routing for timing closure?

    (You can also go to Assignments -> Back-Annotate and do it to routing, which writes out an .rcf file, which has all the routing, but again, only the routing used, not available)

    I need it to understand the patterns in the stratix v architecture. the QUIP program is version 9.0 which only covers till Stratix III.

    Understanding the routing architecture (along with the floorplan) can help you create macros, which are packed placed and routing structures with predictable timing.

    Is Assignments->Back Annotate (with routing) supported on Stratix V?

    thanks.

    Hello,

    This command:

    quartus_cdb --64bit <qpf_name> -c <qsf_name> --back_annotate=routing

    Will produce <qsf_name>.rcf , which contains design routing. It'll also add low-level placement to your <qsf_name>. So back it up before running this command.

    @Rysc

    I disagree that it's only for academic purposes. I actually use placement and routing information to improve performance of my designs.

    Thanks,

    Hello,

    Thank you for this command.

    But I think this command can only dump out used connectivity, not available connectivity.

    Thanks still,

    Hi,

    Were you able to successfully dump all the available connectivity information?

    If so can you please share.

    Thanks
