ID:15560 Can't implement port <name> for enhanced PLL "<name>" -- SCAN_CHAIN parameter of enhanced PLL "<name>" is set to SHORT

CAUSE: The specified enhanced PLL contains an illegal port. When the SCAN_CHAIN parameter is set to SHORT for the enhanced PLL, the Quartus Prime software cannot implement the specified port in the enhanced PLL. An enhanced PLL with a SHORT scan chain value cannot have an FBIN port or E counters. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: Remove the port from the enhanced PLL.
