ID:176104 Can't merge PLL <name> and PLL <name>

CAUSE: The Fitter tried to merge the specified phase-locked loop (PLL)s. However, the PLLs are incompatible or the COMMON_RX_TX_PLL parameter is set to ON. As a result, the Fitter did not merge the PLLs.

ACTION: Refer to the messages which occur below this message in the Messages window or in the Messages section of the Report window for the specific reason(s) why the PLLS could not be merged. To avoid receiving this message in the future, modify the design to make the two PLLs compatible, or use the MegaWizard Plug-In Manager .
