In reply to Tudor Timi:
WoW ! Thanks Tudor ! Appreciate your timely comments/suggestions. I am going ahead with the separate maps for the sub-blocks as given above and its working fine.
But it would be great if they provide support in the UVM libraries for setting the sequencer/adapter for the sub-blocks from the top level block register map.
Anyways it was an awesome learning once again and appreciate your comments on timely manner. !!
