STEP 6: CHANNEL_UP Assertion Check
The criteria for channel_up assertion
verification are:
- The sequence defined in the Aurora 8B/10B protocol being transferred between channel partners
- Successful reception of four verification sequences
Enable loopback mode and check for
lane_up assertions. The CHANNEL_INIT_SM module FSM state
signals must be brought to debug if channel_up is not asserted. For
a simplex link, the simplex TX transceiver might have already achieved
channel_up status. If the TX transceiver needs to be reset as
per the system design, increase the SIMPLEX_TIMER_VALUE attribute based on the
latency between the release of TX_RESET and
RX_RESET . See the Channel Verification Procedure in the Aurora
8B/10B Protocol Specification v2.2 (SP002)
for
channel_up assertion.
