The routing task is one that absolutely screams out for an automated approach. However, past efforts have required a great deal of text-based constraints to get anything near to what you really want.
The routing assistant is a perfect combination of user guidance and automation. It’s a visually assisted approach that allows the layout engineer to simply click on the starting point of the route and then drag the cursor in the direction they want the routing to follow. As the cursor moves along, under the hood the routing engine searches for connections that it can make. When it finds a connection it automatically taps to the pin without the layout engineer having to enter a mouse click. The user simply guides the router with the mouse and it fills in the routing details automatically.
The router is especially good for routing up arrays of FinFETs. FinFET designs have masses of identical common connections and the router understands that. So, as it routes it clones the connections, it has just completed to other parts of the layout. As connections are made in one part of the layout you see them also appear in other areas of the layout that require an identical hook up.
