LogiCORE IP RXAUI v2.1 - Xs are seen in Marvel RXAUI 7-Series timing simulation

Description

When the Marvel RXAUI core is targeting Virtex-7 or Kintex-7 devices, Xs are seen in timing simulation.The problem is that the RXOUTCLK from the GTXE2_CHANNEL transitions from 0->X at the start of simulation.

Solution

To resolve this issue, you have to manually force the RXOUTCLK signal to 0 (through a simulator-specific command) for timing simulation to work. Otherwise the Xs will propagate through the simulation, resulting in the simulation failing to complete successfully.

Thisissue isscheduled to be fixed in the GTXE2_CHANNEL simulation model in the ISE 13.2 software.
