12.1 MAP - Detailed MRP file does not provide accurate LUT utilization number for the Top Level


In the section 13 - "Utilization by hierarchy" of the map, MRP, report file, the top level LUT utilization is not reported correctly.

For instance, in a design where the top level only instantiates lower level modules one would expect very small LUT utilization, if any. However, the report suggests much larger usage, sometimes up to 10000 +.


This issue has been fixed by ISE 12.4.
