Perform a PDN analysis, verifying that the required number of decoupling and bulk capacitors are provided for all power supply rails, including dual-voltage IO supply rails.
Place the decoupling capacitors as close as possible to the supply pins. Larger bulk capacitors can be placed further away.
Use low-ESL capacitors and mount the capacitors with the shortest possible traces to keep the mounting inductance low. For more information, see the Sitara Processor Power Distribution Networks: Implementation and Analysis application note.
Use the bulk and decoupling capacitors values from the SK as a reference when PDN analysis is not performed or results are not available. For filtered (ferrite) power supplies implementation, follow the device-specific SK.
