ID:15506 scanclk port of enhanced PLL "<name>" is disconnected or is driven by GND or VCC -- scanclk port must be driven by a signal
CAUSE: The scanclk
port of the specified enhanced PLL is disconnected or is driven by GND
or VCC
. If you use the scandata
port or the scandataout
port for the serial scan chain loading interface, the scanclk
port of the enhanced PLL must be driven by a signal. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the
MegaWizard Plug-In Manager
.
ACTION: Modify the design so that the scanclk
port is driven by a signal. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
