Resolution To work around this problem, use a GLOBAL_SIGNAL OFF assignment on the destination(s) reset or a global assignment on the source reset to prevent the global routing of the connections. set_instance_assignment -name GLOBAL_SIGNAL OFF -from <source> -to <destination> This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 22.3.
