Abstract: Embodiments include herein are directed towards a system and method for monitoring compliance patterns. Embodiments may include a re-timer device-under-test configured to transmit a truncated compliance pattern associated with a PCIe compliance mode. Embodiments may further include a BFM monitor configured to receive the truncated compliance pattern and to identify a communication signal associated with the truncated compliance pattern. The BFM monitor may be further configured to discard at least one unexpected symbol on at least one lane associated with the communication signal and to collect compliance patterns on all lanes of the communication signal. The BFM monitor may be further configured to align one or more lane FIFOs based upon skew and to enable one or more compliance pattern checkers.
