[partial-reconfig] PlanAhead error in Microblaze-based partially reconfigurable system

[adarshs@xxxxxxxxxxxxxxxxx]

Hello Everyone,

I am developing a system where Microblaze helps to partially reconfigure certain
modules on Virtex-5. I have developed the reconfigurable modules as OPB slaves.
When I define the static and PR regions in PlanAhead, and try implementing the
static portion, I get the following error:

ERROR:Map:95 - Every module in the design should have an AREA_GROUP property.
   There is no AREA_GROUP property on module root block
   opb_socket_bridge_0/opb_socket_bridge_0/Control1_BM

It tells me that no AREA_GROUP constraints are provided for the bus macros. But
Xilinx white papers say that bus macros must not have AREA_GROUP constraints.

I would appreciate it if anyone could tell me how to solve this problem.

Thank you,
Adarsha
