We are starting a new project from scratch and we have a luxury to chose the right platform without any legacy conciderations.
I've used to work for a few years with spectre, but I've heard a lot of good words about eldo.
Is there anybody having hands-on experience with both platforms?
Other than basics, we are interested in phase noise simulation capabilities, switched-cap noise, non-linearity and large signal transfer function simulations.
How is eldo vs cadence simulation speed, convergence in difficult cases, like bsim4 circuits, bugs here and there?
After all, what is the best place to ask about Mentor problems, other than its competitors board?

Hello,

I used to work with Eldo for several years, started with Cadence 2 years ago when I changed jobs (althoug I continue using Eldo for some tasks) and I would say both tools have their strengths and weaknesses.
Mentor's effort in supporting mixed-language simulations (even partially in EldoRF) can be very useful for system level analysis.In your application, SpectreRF's PSS analysis probably better suits your needs in phase noise simulation, switched-cap noise etc than Eldo.
I think Cadence has a much more user friendly framework and for sure offers much better support, be it through Sourcelink, Cadence news group (Usenet: comp.cad.cadence).
Last but not least, Ken had the great idea to create this site, which is very helpful to all of us...
