1.1. Power Model Status

The power models in the Early Power Estimator for Cyclone® 10 GX can be in either preliminary or final status.

Preliminary power models are created based on simulation results, process data, and other known parameters; preliminary power models may change over time. Final power models are corelated to the production device with thousands of designs, and undergo no further changes. The power model status for the selected device is shown in the Main worksheet of the EPE spreadsheet.

The accuracy of the power model is determined on a per-power-rail basis for both the Power Analyzer and the Early Power Estimator. For most designs, the Power Analyzer and the EPE spreadsheet have the following accuracies, with final power models:
  • Power Analyzer: Within 10% of silicon for the highest power rails, assuming accurate inputs and toggle rates.
  • EPE spreadsheet: Within 15% of silicon for the highest power rails, assuming accurate inputs and toggle rates. Recommended margins are shown in the report tab (see Report tab section) .

See Section 5 for information on factors impacting power estimation accuracy.
