1 Using the Power Estimation Tool

The input part of the spreadsheet consists of the following three sections: Processing Elements, Interfaces, and Power Report.

To use the input part of the spreadsheet, users must modify the fields with their appropriate usage parameters. Cells designed for user input are in yellow. Fields that cannot be modified are gray. Fields in blue are the output calculated power. Configure the yellow cells to a value most closely aligned with your intended scenario.

The purpose of each of these sections is:

  • Processing Elements:
    • Configure frequency of operation for R5F, M4, and DSP and HWA
    • User-estimated percent utilization of each core
  • Interfaces:
    • Subset of commonly used major interfaces with selectable mode
    • Subset of commonly used major interfaces with percent utilization
  • Power Report:
    • Selectable VDD, VDD_SRAM, VIOIN
    • Power estimation output by rail
    • Power rails are aligned with EVM design
