The make_connection command will connect the source signal to the destination block port. If the port has an existing connection, the command will remove the previous connection and connect it to the specified signal. make_connection expects 3 arguments: from - output net of the source block of the new connection, OR tieoff - tieoff value to - name of the destination block port - the input port name of the destination block Note that the changed path will be routed immediately. If the path contains a node that is created during ECO compilation, then the paths will be routed after the node is placed with place_node command.
