Compliance Pattern Transmission Support
The LTSSM state machine can enter the polling.compliance substate where the
transmitter must transmit a compliance pattern as specified in the PCIe Base
Specification 2.0. The polling.compliance substate is intended to assess if the
transmitter is electrically compliant with the PCIe voltage and timing specifications.
The compliance pattern is a repeating sequence of the following four code groups:
■
■
■
■
The PCIe protocol requires the first /K28.5/ code group of the compliance pattern to
be encoded with negative current disparity. To satisfy this requirement, the PIPE
interface block provides an input signal (tx_forcedispcompliance). A high level on
the tx_forcedispcompliance signal forces the associated parallel transmitter data on
the tx_datain port to transmit with a negative current running disparity.
For 8-bit transceiver channel width configurations, you must drive the
tx_forcedispcompliance signal high in the same parallel clock cycle as the first
/K28.5/ of the compliance pattern on the tx_datain port. For 16-bit transceiver
channel width configurations, you must drive only the LSB of the
tx_forcedispcompliance[1:0] signal high in the same parallel clock cycle as
/K28.5/D21.5/ of the compliance pattern on the tx_datain port.
