Just installed the update, and there is a bunch of new cool toys!
1. Coupling analysis. You pick a set of traces or create "Directed group" (all traces connecting component X with component Y) and run analysis. Once it's done, you can see results either as a "heatmap" or as a table, which shows info on a per-segment basis.
2. Impedance analysis. Same workflow as above, very useful for identifying things like parts of traces which are not over reference plane.
3. New "Route Vision" which highlight various issues with layout like 90 degree turns, non-optimal pad entry, etc..
4. More improvements for 3D Editor - now supports semi-transparent layers, window select allows to display 3D view of selected part of board only, now any objects that are placed on top of vias' and pads' barrels are eliminated (as they would "fall into" the barrel in reality unless the barrel is plugged).
4. A whole bunch of features which were previously only available at Allegro license level now are available at Pro level:
- Timing Path support for Z-Axis Delay. Basically this means that trace length now can include z-distance along portions of vias when signal transitions between layers.
- Pin delays can be also included into calculating trace lengths for match groups and differential pairs.
- Differential Pair Dynamic Phase Control is also now available at Pro license level!
- Full support for backdrills.
There are more features, but I didn't have a chance to play with them yet, and some might only be available at higher license levels only. There are also some improvements to Capture, but I too didn't get to try them out yet. Overall - very good update, certainly worth the price of sub!
