It isn't true that Mentor have produced the first topology planner.
Zuken introduced topology planning in Lightning version 5.0 in the summer of 2005.
Please have a look at http://www.zuken.com/cr-5000/preditor.asp
Trunking: The Trunking routing solution is based on intelligent trunk objects, which allow easy high level design planning, avoiding unnecessary loops. It addresses issues associated with handling different routes, busses, or differential pairs collectively as one entity, enabling users to quickly sketch routes facilitating fast up-front planning and manipulation of a collection of signals as a group. All interconnects can be concurrently considered when routing at the ends of a trunk using the trunk end router function, combating design complexity as the board density increases. It also enables painless non-destructive design modifications and obeys constraints like Length, Skew and Delay. During routing it allows users to change signal order within the trunk to ensure successful connectivity at any stage.
