ID:15562 Enhanced PLL "<name>" uses inclk0 and inclk1 ports, but clkswitch port is unconnected, and SWITCH_OVER_ON_LOSSCLK and SWITCH_OVER_ON_GATED_LOCK parameters are set to OFF

CAUSE: You specified an enhanced PLL that uses the inclk0 and inclk1 ports, but the clkswitch port is not connected, and the SWITCH_OVER_ON_LOSSCLK or SWITCH_OVER_ON_GATED_LOCK parameter is set to OFF. To initiate a clock switchover, the enhanced PLL must have the clkswitch port connected, or set the SWITCH_OVER_ON_LOSSCLK or SWITCH_OVER_ON_GATED_LOCK parameter to ON. This warning usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager to modify the design so that the clkswitch port is connected, or set the SWITCH_OVER_ON_LOSSCLK or SWITCH_OVER_ON_GATED_LOCK parameters to ON.
