Wire information is resolved through a process known as pin propagation. The wire information is known from the system input and this information is propagated in module order until it reaches the system output pin. To trigger pin propagation, click on the Propagate changes button ( ) on the toolbar. Alternatively, right-click on an empty part of the canvas and select “Redraw” from the context menu.
