DDR input without DPA in Arria II GX

Friends,

I am trying to use the dpa with external PLL but I am getting the fitter warning and error

DPA clock of SERDES receiver atom "rx_0" is driven by PLL "PLL_NAME" with unspecified dpa_multiply_by and dpa_divide_by parameters

Error: The lvds clock and the DPA clock frequency of SERDES receiver atom "rx_0" must be the same

The following support for interfacing DPA to external PLL does not apply because I do not see the option of "Use these clock settings for dpa clock" in PLL/lvds generated for Arria II GX

Thanks in advance for your help!
