4. Power Analysis and Estimation
4.1. Early Power Estimator
The Early Power Estimator (EPE) is a power estimation tool that helps you estimate
the power consumption of your design during the system planning phase for proper
power supply planning and consideration.
The EPE allows you to enter design information based on architectural features and
calculates the power consumed by each architectural feature. Inputs to the EPE are
environmental conditions and device resources (such as clock frequency, RAM blocks,
and digital signal processing [DSP] blocks) that you expect to use in your design. The
EPE then calculates the static and dynamic power, current estimates, and thermal
analysis for the design.
You can either enter the design information manually into the spreadsheet or import a
power estimator file of a fully or partially completed design from the Intel Quartus
Prime software. After importing a file, you can edit some of the input parameters
including V
CCINT
, ambient temperature, airflow, clock frequency, and toggle percentage
to suit your system requirements.
The value obtained from the EPE is only an estimation and should not be used as a
specification. The accuracy of the EPE results depends on how close your input of the
design information into the EPE resembles that of the final design.
For more information about the EPE, and how to generate and import the power
estimator file, refer to the respective user guides.

4.2. Power Analyzer
The Power Analyzer tool in the Intel Quartus Prime software is a power analysis tool
that helps you calculate your design power consumption accurately to ensure thermal
and power supply budgets are not violated after your design is complete. The Power
Analyzer tool requires your design to be synthesized and fitted to the target device.
Availability of information such as design resources, how the design is placed and
routed on the target device, and the I/O standards assigned to each I/O cell allow the
Power Analyzer tool to provide accurate power estimation.
The process of using the Power Analyzer tool consists of the following three parts:
• Specifying sources of input data
• Specifying operating conditions
• Running the Power Analyzer tool
