Start with the news release Autorouting package shows its intelligence from Zuken, which we summarised at the time by saying "Routing environment applies all the knowledge required for the latest high-speed boards with a guided step-by-step process to deliver right-first-time results in less time.". Several months prior to that, we featured the news release Router adds intelligence to automation from Mentor Graphics UK: "Revolutionary routing technology combines the knowledge of an engineer, skill of a board designer and power of an autorouter.".
 
In August 2006, we covered the news from Adept Scientific - take a look at Budget PCB package improves reverse engineering which says: "Affordable printed circuit board design system integrates schematic capture and PCB layout with features normally found in the world's most expensive PCB design systems.".
 
Take a look also at the news release from Mentor Graphics UK, Software promises faster route to big boards, as well as Budget design package boasts high-end features from Adept Scientific, and Windows-based PCB system comes up to date from Mentor Graphics UK.
