I have looked at the document "SLLU149E–June 2011–Revised February 2016" Chapter 5 particularly about USB connections. The sections 5.3 and 5.4 describe high-speed differential routing and supper-speed differential routing respectively. I don't find any information about routing guideline for the signals between MCU and USB Transceiver. The ULPI (8 bit 60 MHz) and PIPE (16 bit 250 MHz). Do we have any length matching requirements for ULPI and PIPE signals ?
