1 Using the Power Estimation Tool

The input part of the spreadsheet consists of six sections: Operating Performance Point, Processor Core Utilization, LVCMOS IO, Peripheral, Estimated Power, and General. To use the input part the spreadsheet, users must modify the fields with their appropriate usage parameters. Cells designed for user input are in blue. Fields that cannot be modified are red. Fields in green are the output calculated power. Configure the blue cells to a value most closely aligned with your intended scenario.

The purpose of each of the four sections is:

  • Operating Performance Point: Configure frequency of operation for A53s, R5s, M4, and ICSSGs.
  • Processor Core Utilization: User estimated percent utilization of each core.
  • LVCMOS IO: Subset of commonly used IO with selectable mode and percent utilization.
  • Peripherals: Other peripherals with selectable mode and percent utilization.
  • General: High level system configuration.
  • Estimated Power: Power estimation output by rail. Power rails are aligned with EVM design. Selectable VDD_CORE.
