why the MGT Link Status is not linked in chipscope analyzer when using IBERT

The question is about the IBERT, first let me describe the phenomenon i encountered:

i use IBERT core generator to generate the bitstream file and download it  to my board to test the BER of my design, then i open the IBERT console, in the clock setting i finded that the TXOUTCLK0 DCM Status is not locked, there is no use even i reset it. and in the MGT/BERT setting i finded that the MGT Link Status is not linked, after choose loopback mode to near_end PCS and reset the channel, the status is still not linked. Except for the two status other status are all locked, how could i solve this problem? Can anybody help me? Thank you very much.

 

the FPGA i used is FX130t and the chipscope release is 11.5

Hi,

 

Whether the input clock (GTP Refclk) pin location is properly specified while generating IBERT core?

 

Please confirm this.

 

Thanks,

Srinadh
