Routing Across Safety IP Partitions

The Intel® Quartus® Prime software strictly preserves all logic and routing configuration in safety IP.

However, you can route across a safety IP if long routing lines are available that cross over the safety IP without requiring changes to any programming bits in the safety IP area.

To route across a safety IP if pin and LogicLock placement restrict the routing from your nonsafety IP to the pins, adjust the pins or LogicLock region locations to free up the necessary routing.
