The detailed route shows some warnings regarding nets not visiting certain pins and falling back to feed through mode. I want to to understand what these particular warnings mean and why they are showing in my flow.
There are over a thousand warnings of similar patterns and I have only showed a sample of it. The detailed route ultimately runs without any errors but these warnings remain
Expected Behavior
The detailed route to continue without any warnings
