The input part of the spreadsheet consists
of the following sections: operating performance point, processor core utilization, LVCMOS
IO, peripheral, estimated power, and general. Users must modify the input fields with
appropriate usage parameters that represent the specific application use case. 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.
Note: This tool does not have the complete
set of IOs possible on the AM62L. Any IO configuration must be confirmed through the AM62L
pinmux tool.
Purpose of each of each section:
- Junction temperature: This section lets
the user select the junction temperature (not ambient temperature) in Celsius (°C) up to
125°C.
- Process corner: Typ or Max (‘Typ’ is the
typical power consumption of most devices. ‘Max’ is the worst-case possible due to silicon
variation).
- Processor cores : Allows to configure the
A53 frequency of operation and user estimated percentage of computational utilization for
each core.
- LVCMOS IO: Subset of commonly used IO
with selectable mode and percent utilization.
- Peripherals: Other peripherals with
selectable mode and percent utilization.
- Estimated power: Power estimation
itemized by supply group. Power supply consolidation/groups rails are aligned with EVM
design.
