How to Control Skew Between the Four
Lanes
From the InfiniBand specification, an InfiniBand device is expected to
accept a given lane skew. You can artificially insert a delay between the
four lanes to verify that your DUT fulfills this InfiniBand requirement.
To insert a delay between lanes:
1 Select Generator>Lane Skew.
The Lane Skew Settings and Status dialog box opens.
2 In the Transmit Lane Skew list, set the delay (in symbol times)
between the lanes for each lane by means of the adequate lists.
3 Click Apply.
The DUT should then notice the lane skew and reacts as expected.
