ID:15507 SCAN_CHAIN parameter of enhanced PLL "<name>" must be specified when using real-time control of advanced parameters

CAUSE: You did not specify the SCAN_CHAIN parameter of the specified enhanced PLL and you are using real-time control of the advanced parameters of the specified PLL. For example, you may have connected the scanclk port of the specified enhanced PLL. The SCAN_CHAIN parameter of the specified enhanced PLL must be specified when you use real-time control of the advanced parameters of the specified enhanced PLL.

ACTION: Modify the design and specify the SCAN_CHAIN parameter of the specified enhanced PLL, or do not use real-time control of the advanced parameters; for example, by disconnecting the scanclk port.
