Improting Eagle CAD based designs into Allegro,Mentor, or other high end packages?

Dear group

I've done a somewhat complex design with Eagle CAD, but I'm facing several limits of this software (in terms of simulation to name one important thing). As a result, I like to upgrate to a more powerfull package alowing me to simulate complete designs and maybe also having some better support for laying out big BGAs, lenght matched trace lenghts etc.

What I'm concerned though is wether I can import my design to an as high degree as possible or if I have to redo it completly. The latter would be bad, since there are several months of layout work in it.

I thought to ask here cause you people may already have specific experience rather than trusting sales drones...

I'm currently mostly after simulating, so some simulation pakage that could reliably import this Eagle desing would be a potential solution also.

Any ideas?

TIA

What sort of simulation : are you after high speed transmission / crosstalk IBIS style simulation [eg Hyperlynx etc], or do you mean Spice Analog Circuit operation simulation ?

If you want to translate Database, then something like

would look to be what you want ?. Cheaper than several months work! Once converted, you can export back netlists, and run connectivity and clearance checks, to make find any little errors.

My general experience with translators is they are quite good, and will save a LOT of time. - but they do need manual checking to make sure all physical info came across OK. I've seen QFP fingers spun wrong by quadrant, or complex PADS stacks simplified, but those effects are pretty easy to spot! :) - and not too hard to correct.

Then you ceate a netlist, and manually tick that off, against the original.

Complex NET based design rules are not usually translated, so those you re-enter.

You hit the nail with Hyperlynx

Thanks for the pointer to cadware

Pulsonix does quite a good job importing Eagle designs and libraries. It has a good simulator and includes matched trace lengths. The autorouter is very good, also.
