Yes, it is true. Genesis is the way to go if money is a concern. I've used and loved MWO in the past, but now I'm forced to use Genesys. Most of my applications are below 1GHz so I rarely need to simulate transmission lines since they have much less effect on my performance so I cannot compare performance since my MWO usage was in the 800MHz to 2.5GHz range.
Agilent has been doing some interesting things with the Genesis package. After a rough start in 2005, their latest version is very nice.
I have no experience with with MWO; I had used EESOF series IV back in the day and briefly used ADS. I've been using Genesys for almost 10 years.
Other than designing IC's -- I don't really see how Genesys is going to hold you back. I regularly design linear/nonlinear/passive circuits from 2 MHz to >10 GHz. Since I have prototyping and measurement capabilities here to 20 GHz, I have a pretty good handle on the "measured versus modeled" problem; and I've seen no inherent flaws in any Genesys analysis recently. A few years ago I pointed out a problem with their interdigital capacitor model and provided them data... and they worked on/fixed their model (this was maybe in 2002 or so?), and wrote it up as an appnote.
The place where I see things fall apart, almost universally, is with the vendor nonlinear models (I normally find them myself and enter them into the tool), not anything that is under the control of the CAE vendors.
I expect that at the core, all of the simulators are very similar in their accuracy and capabilities. Sure, some models will be better than others, some engines might be faster than others, but I expect they are all pretty "good". Then it comes down to which interface you prefer, whether you feel you are well supported, and what you can afford.
I happen to really like the Genesys interface and capabilities, and the Genesys users are seeing some nice synergy with Agilent (i.e. there is a sharing of technologies BOTH WAYS between Genesys and ADS). Genesys has certainly benefited from having Momentum and such.
Anyone going to MTT/IMS 2009 should stop by the agilent booth; we're having a Genesys user group meeting/lunch/presentation on Wednesday next week.
Disclosure:
I don't work for Agilent -- I do work with them for mutual promotion of Genesys and my consulting business.
