描述

When an AREA_GROUP constraint for an Area Group containing TBUFs, MULTs, or block RAMs does not have a range for these components, the following occurs in the Area Group summary of the MAP report: 

AREA_GROUP AG_U1 

Number of Tbufs/Block RAMs/Multipliers: xx out of 0 0% (OVERMAPPED)  

How can I avoid this OVERMAP message in the MAP report?

解决方案

To avoid this over-mapped message, give any of these components in the Area Group a valid range in the AREA_GROUP constraint.
