ID:15562 Enhanced PLL "<name>" uses inclk0 and inclk1 ports, but clkswitch port is unconnected, and SWITCH_OVER_ON_LOSSCLK and SWITCH_OVER_ON_GATED_LOCK parameters are set to OFF
CAUSE: You specified an enhanced PLL that uses the inclk0
and inclk1
ports, but the clkswitch
port is not connected, and the SWITCH_OVER_ON_LOSSCLK
or SWITCH_OVER_ON_GATED_LOCK
parameter is set to OFF
. To initiate a clock switchover, the enhanced PLL must have the clkswitch
port connected, or set the SWITCH_OVER_ON_LOSSCLK
or SWITCH_OVER_ON_GATED_LOCK
parameter to ON
. This warning usually occurs when you instantiate a megafunction directly in a text file rather than using the
MegaWizard Plug-In Manager
.
ACTION: To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager to modify the design so that the clkswitch
port is connected, or set the SWITCH_OVER_ON_LOSSCLK
or SWITCH_OVER_ON_GATED_LOCK
parameters to ON
.
