Unconstraint Clock in Stratix V Designs with GXB Transceiver and Transceiver Reconfiguration Controller Megafunction

When you run a full timing analysis on a Stratix V design that contains a GXB transceiver block and a Transceiver Reconfiguration Controller megafunction, the TimeQuest timing analyzer reports an unconstraint clock. The timing report shows the following:

alt_xcvr_arbiter:pif[0].pif_arb|grant[0] was determined to be a clk but was found wt/o an associated clock assignment

This issue affects Stratix V designs that contain GXB transceiver block and Transceiver Reconfiguration Controller megafunction.

No workaround.This issue will be fixed in a future version of the Triple-Speed Ethernet MegaCore function.
