Re: @DS or MWO
Concerning accuracy, both programs seems to give approx the same result. I have performed linear simulations up to 30 GHz in microstrip structures using both programs.
MWO is much faster, however. And is more user friendly too. But the EM simulator in ADS, the Momentum, seems to be a bit better developed than the corresponding feature in MWO.
For nonlinear simulations there is a volterra series analysis feature in MWO for circuits in light compression, in addition to the standard harmonic balance feature for circuits driven into high compression. Volterra series analysis is said to provide more accurate and faster results in the latter case. This is heavily denied by Agilent who says ADS' HB is accurate during all compression conditions. Accuracy is in the final run heavily depending on the semiconductor model used.
A nice feature with ADS is that it can import and export results to/from CST Microwave Studio 3D EM simulator. Which is the king of 3D Electromagnetic simulators (far better than e.g. HFSS in my opinion).
For a time being, MWO was much cheaper than ADS, i.e. more bang for the buck. But with the new price policy by AWR, the difference is now only marginal.
Another very promising microwave CAD program is Genesys by Eagleware (
www.eagleware.com). Well worth to take a close look at.

Hi there,
I am curious to know which software gives better simulation results in terms of circuit simulation, @DS or MWO? Any opinion will be appreciated. Thanks.
Linda.
