ID:176403 Following nodes drive the PLL "<name>" placed at location <text> via the cascade connection, but only one can use this connection

CAUSE: More than one node drive the clock input of the specified (PLL) via the cascade connection and not through a global, regional, or periphery clock network. This error may occur if the PLL is driven by another PLL and by a clock output from a HSSI block.

ACTION: Assign one of the nodes to drive to this PLL via the clock network.
