RE: [partial-reconfig] Final Stage on Module-Based Partial Reconfig

["Michael Florian" <MFlorian@xxxxxxxxx>]

Hi Dani,

what do you mean by "I used the Bus-Macro in all compilations"?
The Bus-Macro must be instantiated *only* in the top_level.vhd.
In the top_level.ucf, it must be loced to an appropriate slice.
MAP and PAR of the static part of the design need the related
bus_macroxxx.nmc to be copied to the local directory.
That actually works for me ;o)

Regards,
Michael

Subject: [partial-reconfig] Final Stage on Module-Based Partial Reconfig


  Hi,

  I´m trying to run the Module-Based flow for Partial Reconfiguration as 
explained in XAPP290.pdf.

  I followed all the indications step by step and after some problems I got 
to the Final Assembly Stage. But there, I have some unbelievable problem: 
PAR takes the Bus-Macro out!! Bitgen fails in the DRC, finding a lot of 
unplaced components and completely unrouted nets, all of them part of the 
Bus-Macro and when I looked back I found using the  FPGA Editor that the 
Bus-Macro wasn´t in the last .ncd; there are both sides (the fixed side and 
the reconfigurable) but not the intermediate Bus-Macro.

  Does anyone have this problem?

  I give more information (:-D : In the Active Module Phase, I used the 
Bus-Macro in all compilations with each module, because I think it must be 
said where to route the signals. That´s why in the Final Assembly Phase both 
sides (the 2 .ncd it takes for assembling) have in common the bus-macro.

  Could it be that the problem?? I´m really lost. If anyone has a clue it 
will be welcome.

  Thank you,

  Dani
