131. Virtex-7 MAP - Utilization summary has incorrect number of total sites.

Description

The MAP design utilization summary will print incorrect totals for some component types:

Number of BUFG/BUFGCTRLs: 4 out of128equals 3% (should be a total of 32)

Solution

This problem occurs for site types on multi-die devices where only the sites on the master die are eligible for use. The amount of error will be in proportion to the number of die. This problem will be fixed in ISE 13.1 software. Meanwhile do not use these totals to determine the device capacity.
