2.2. Intel® FPGA PTC Power Model Status

The Intel® FPGA Power and Thermal Calculator (PTC) uses a device power model to calculate estimated power consumption and thermal assessments. Depending on the maturity of the device, the power models in the current version of the Intel® FPGA PTC may be in advance, preliminary, or final status. The status of the power models relate to the accuracy of the estimated results.

The Main page of the Intel® FPGA PTC shows the current power model status for the target device:

  • Advance power models— based on simulation results, process model projections, and design targets. Advance power models may change over time.
  • Preliminary power models—include post-layout simulation results, process data, and initial silicon correlation results. Preliminary power models may change over time.
  • Final power models—correlate to production devices with thousands of designs, and are not expected to change.

The accuracy of the power model is determined on a per-power-rail basis for the Intel® FPGA PTC.

  • For most Intel® Stratix® 10 designs, the Intel® FPGA Power and Thermal Calculator has the following accuracy, assuming final power models: Within 15% of silicon for the majority of power rails with higher power, assuming accurate inputs and toggle rates.
  • For most Intel® Agilex™ 7 designs, the Intel® FPGA PTC has the following accuracy, assuming final power models: Within 10% of silicon for all power rails, assuming accurate inputs and toggle rates.
