we are also very bored with Mentor, especially as we have a bunch of ES licenses that will not support 3D now.
We are considering moving at least five seats to Cadence since Allegro and Orcad are now merged into one product and share the same database.
That will give a perfect mix for us since we have fancy high speed designs as well as about 50 simpler designs with up to 10 layers as well as simple test adapters that can be done with a simpler tool but need the same database.
In our impression mentor is like a slot machine: You can insert endless amounts of money but you never know if you will get a reward.
