ID:15046 PLL "<name>" has clkswitch port stuck at VCC or GND

CAUSE: You tried to use clkswitch port with the specified PLL, but the port is stuck at V_CC or GND. As a result, the inclk0 or inclk1 port will not be used and the PLL input clock cannot be switched.

ACTION: To avoid receiving this message in the future, modify the design so that the clkswitch port is driven by a signal other than V_CC or GND, or disconnect the unused inclk0 or inclk1 port.
