I am getting a few critical warnings when importing and existing ISE project into planahead. Im attempting to create a floorplan for my project.
One thing that is greatly confusing me is if i go to ISE > User Constraints > Floorplan Area Logic it opens the project just fine, importing the microblaze just fine, however with this method i can not compile or look at timing in floorplanner itself to make adjustments as needed with my pblocks, unless there is a method that i am missing.
If i open planahead on its own, and create a new project using the new project > imported project and select my ise project, and run synthesis i recieve the two following critical warnings that i do not recieve when opening via the other method:
[EDIF 96] Could not resolve non-primitive black box cell 'microblaze_sys' defined in file 'main.ngc' instantiated as 'Inst_microblaze_sys'.
[Designutils 977] Could not find ref fast_clock. The UCF file d:\Cosmiac\Local\Floorplan\CubeSat\CubeSat.srcs\sources_1\ip\fast_clock\fast_clock\example_design\fast_clock_exdes.ucf will not be read for this ref.
The main part of this project i am trying to constrain using floorplanner is the microblaze_sys. I am still able to right click and select draw pblock, however the issue im having is that the estimated physical resources list is no populating so i do not know what slice number brams number etc that i need in order to draw the area on the chip.
I have read that this is a known bug and can safely be ignored, but because that list is not populating ignoring it gives rise to other problems that I do not know how to solve

I think you would receive a better response to this post if you posted it in the Design Tools section of the forum. This area is dedicated to Xilinx Boards and Kits.

I see that this issue has already been taken to the Design Planning forum where it belongs.
