Why does the CPRI v6.0 Intel® FPGA IP generate multiple start-of-packet words on the GMII RX Output?


Due to a problem with the CPRI v6.0 Intel® FPGA IP core in the Intel® Quartus® Prime software v17.1, you may observe multiple initial start-of-packet on the GMII RX output if there are idle cycles in the gmii_rxdv within a packet. 


No workaround for this problem exists.

This problem has been fixed in Intel® Quartus® Prime Edition software version 19.1.
