Adarsha,
You should physically put the BMs on the top (not only in the UCF).
If you change your design and the way it is built and portioned I assume you
would need to change the UCF as well but if I am not mistaken the PlanAhead
does it all for you.
Follow the example it tells you where to put the nmc files (If I remember
correctly it's in the same directory as the directory for the top netlist.)

Hi Mati,

By placing the BM in top level, do you mean that I should change the 
constraint
(.ucf) file? Also can you tell me where the .nmc files need to be placed. I
have tried placing them in different places but with no success.

Thanks,
Adarsha
