2.1. 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.)
- For most Intel® Stratix® 10 designs, the Intel® Quartus® Prime Power Analyzer has the following accuracy, assuming final power models: Within 10% of silicon for the majority of power rails with higher power, assuming accurate inputs and toggle rates.
- For most Intel® Agilex™ designs, the Intel® Quartus® Prime Power Analyzer has the following accuracy, assuming final power models: Within 10% of silicon for all power rails, assuming accurate inputs and toggle rates.

- Intel® Stratix® 10 HBM2 IP
- Intel® Stratix® 10 HPS IP
- Intel® Arria® 10 HPS IP
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 obtain power estimations using the Early Power Estimator spreadsheet (EPE).
