14.7 Xpower Analysis - "WARNING:Power - Processor frequency 1000.0 Mhz exceeds the MAX allowed 667.0 Mhz for this device..."

Description

If I launch Xpower Analysis (XPA), the following messages appear:

WARNING:Power - Processor frequency 1000.0 Mhz exceeds the MAX allowed 667.0 Mhz for this device 
XML load 0% complete^MXML load 0% complete^MXML load 100% complete
WARNING:PowerEstimator - Power estimate is considered inaccurate. To see details, generate an advanced report with the "-v" switch.
Running Vector-less Activity Propagation

What does this message mean?

Solution

The message is informing you that the clock frequency of the processor (PS) is above the maximum frequency of the silicon. The Power Analysis results will be inaccurate for clock frequencies above this maximum limit of the PS.
