EIGRP Routes turn active

Hi,
I am still not able to understand “During this local computation, the route remains passive. If there is no feasible successor in the topology table, the router will start a diffusing computation and the route will go active”. what exactly should happen to let a route turn into active ( one is SIA scenario) ?
