ISE - Why is the Synthesis report of IDELAYCTRL different than the MAP report?

Description

My design has only one IDELAYCTRL as listed in the Synthesis report. Why does the MAP report indicate that the IDELAYCTRL components are 100% utilized?

Solution

When using one IDELAYCTRL component without location constrain, MAP duplicates other unused IDELAYCTRLs and will always report 100% IDELAYCTRL utilization.
