Hi Glenn,
While the overall resource usage may be low, are you perchance using
a lot of BRAMs and/or multipliers?
Thanks,
Henry

Hello,
I have a design which easily fits in an iBOB, which I modified
slightly (but not enough that I would think it would cause fitting
problems) and now I am getting errors like this from map:
Phase 12.9
ERROR:MDT - :Place:543 - Due to placement constraints, the following 2
components
cannot be placed. The relative offsets of the components are shown in

Has anyone seen this sort of thing before? What is the usual culprit?
I think I'll be able to work around it by tweaking things a bit, but
just curious.
Thanks,
Glenn
