I've been asked to find a circuit design / layout and simulation software that will work well with ProE. The initial request was just to be able to export a 2D circuit diagram to some format ProE could import into a drawing (such as .dxf). However, if making such a purchase I want to get something that is more functional and can produce more intelligent data that might interface well with ProE's Ecad modules. I've never used the Ecad functionality, but a couple of emails that have come across on the exploder indicate it is a great tool. Can anyone out there that is regularly doing circuit board design & simulation recommend something that interfaces well with ProEngineer?
