1.1. Power Analysis Tools

The Intel® Quartus® Prime Design Suite provides tools to analyze the power consumption of your FPGA design at different stages of the design process.

  • Intel® FPGA Power and Thermal Calculator (PTC)—estimates power supply and system thermal requirements before compiling the design, or anytime during the design phase. Supports Intel® Stratix® 10 and Intel® Agilex™ devices.
  • Intel® Quartus® Prime Power Analyzer (QPA)—estimates power consumption for a post-fit design, allowing you establish guidelines for the power budget.
  • Early Power Estimator (EPE) spreadsheet—estimates power consumption for power supply planning before compiling the design. Supports Intel® Arria® 10 and Intel® Stratix® 10 devices. (For versions of the Intel® Quartus® Prime software later than version 19.4, Intel® Stratix® 10 devices are supported in the Intel® FPGA Power and Thermal Calculator.)

Data outputs
Note: The EPE and Power Analyzer outputs vary by device family.
  • Total thermal power dissipation
  • Thermal static power
  • Thermal dynamic power
  • Off-chip power dissipation
  • Current drawn from voltage supplies
  • Total thermal power
  • Thermal static power
  • Thermal dynamic power
  • Thermal I/O power
  • Thermal power by design hierarchy
  • Thermal power by block type
  • Thermal power dissipation by clock domain
  • Device supply currents
Estimation of transceiver power for dynamic reconfiguration features Includes an estimation of the incremental power consumption by these features. Not included
Note:
The Intel® Quartus® Prime Power Analyzer does not support power analysis of the following Intel® FPGA IP:
  • Intel® Stratix® 10 HBM2 IP
  • Intel® Stratix® 10 HPS IP
  • Intel® Arria® 10 HPS IP
In versions of the Intel® Quartus® Prime software later than 19.4, you can obtain power estimations for the Intel® Stratix® 10 HBM2 IP and Intel® Stratix® 10 HPS IP using the Intel® FPGA Power and Thermal Calculator (PTC).

For power estimation of Intel® Arria® 10 HPS IP, and for power estimation in the Intel® Quartus® Prime software version 19.4 or earlier, you can can obtain power estimations using the Early Power Estimator spreadsheet (EPE).
