1. Overview of the Power and Thermal Analyzer

Updated for:
Intel® Quartus® Prime Design Suite 25.3

This document describes how to use the Power and Thermal Analyzer (PTA). The PTA estimates your design's power consumption and provides thermal design parameters for Agilex™ and Stratix® 10 devices.1 The PTA allows early analysis of the factors contributing to FPGA power consumption, allowing you to adjust your design for greater power and thermal efficiency.

Key abilities of the PTA include:

  • Estimate the power consumption of your design before creation, and at various stages during the design process based on design hierarchy.
  • Determine preliminary thermal assessments of your design.
  • Section data input and results along hierarchical boundaries to view and improve power consumption per design hierarchy.
  • Export, import, and reuse PTA data for a particular design hierarchy.
Note: Power and Thermal Analyzer (PTA) results are an estimate of power consumption and thermal properties, not an exact specification of actual consumption during device operation because actual consumption is affected by the device and design input signals. Refer to Measuring Static Power for information on how to measure device static power in a way that correlates with the way that the PTA reports static power.

Once your design is ready to compile, switch to the Quartus® Prime Power Analyzer for more accurate power analysis results. The Quartus® Prime Power Analyzer produces more accurate results because the Compiler generates more detailed information about your design that influences the analysis tool, such as routing and configuration information that affect power consumption.

1 The PTA does not support Arria® 10, Cyclone® 10, or earlier devices. Use the legacy Early Power Estimator (EPE) for earlier devices.
