8.10. Unused Transceiver RX Channels Settings

Add the following Intel® Arria® 10 QSF assignments to prevent performance degradation of unused RX serial clock over time. You can either use a global assignment or per-pin assignments.

Syntax

set_global_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON

set_instance_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON -to <pin_name (U34, for example)>

An example of a <pin_name> is U34, not PIN_U34.
