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

描述

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?

解决方案

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