L1 is not clearly marked DNF

Problem environment

The optional 10uH inductor L1 is not needed when VDDCORE is correctly balanced.

Steps to reproduce

  1. Observe the layout
  2. Examine L1 notation

Expected result

The L1 inductor should clearly state DNF, to indicate its optional quality.

Actual result

The L1 inductor is unmarked and implies mandatory population.

Severity level

This is low priority because the device proves correct with L1.

Try removing L1 from a prototype and test stability to test for required population.
