I've often wanted the ability to unstack and cut through a PCB design like this. As the article points out, it is only in the last few years that graphics horsepower has allowed the 3D manipulation that this kind of display requires. If PCB could do this (some day) it would be great. > > So, that's all it takes today to be "5th ranked in EDA". Lest we loose sight of the larger picture... I think it takes a bit more than this. The main strength of ADS has (in my opinion) been its ability to accurately model complex RF an u-wave circuits. It's biggest drawback has been the UI and to some extent the documentation. I'm pleased to see they finally addressed this shortcoming. So, it's not as if making a fancy UI allows you to be "5th ranked" but rather that when you make the UI as good as the rest of the tool you can have a "5th ranked" solution. (Full disclosure - I've used this program quite a bit in the past as a former HP and Agilent employee.) Joe T > > > John Griessen > >
