The PDG lists a lot of topology of different signals and also has suggestion of total trace length. The trace length usually limits the minimum and maximum length.
I know why the trace has maximum length limitation but how about the minimum length? Fox example, the USB 2.0 external toplology total trace length is from minimum 3" to maximum 12".
If the connector is really close to the chip. Do I need to follow minimum 3" limitation by extending the traces?
