I got reply form Altera feedback, it seems that the GT device just can not use this CPRI core although some low level functions are good.Is that a kind business strategy or do having technical problems?:cool:

Dear Sir:
Your query on the Altera SW Depot has been redirected to the Altera technical documentation team.
The CPRI MegaCore Function User Guide states that the CPRI IP core does not support Stratix IV GT devices: the Device Support table clearly states that the IP core provides Stratix IV device family support only for Stratix IV GX devices. However, as you found, the Quartus II software does not prevent you from generating an IP core variation that targets such a device.
The technical documentation team is not equipped to provide technical support. For further assistance, we recommend that you file a support request at myAltera.
Liz
