Let's face it. AWR is very user friendly. If you don't use ADS for long time you find youself learning it again, AWR is diffferent. You find ADS usefull for complicated tasks such as PLL etc. You can Use ADS such as MATLAB. But!!!! for a regular task for example: VCO design, MMIC Amp design , Filters etc AWR is several times faster!!!. You can tune very fast several parameters with the AWR. ADS it takes forever.
Momentum of ADS(EM simulation) is much better than AWR. This is very reliable software and personaly I like it. CST is EM for 3D which you can't do with ADS or AWR.

Hi
For me MWO is a good RF software simulator. It's very easy to use and the result is good. With the new version, the Harmonic Balance simulation became faster than Ansoft serenade on several examples.
I had made an oscillator with doubler and I had compraed the practicals results with Ansoft and MWO simulations. MWO was better on harmonic level, bias conditions and frequency.
The ig advantage of ADS is momentum but now with the link with Sonnet with MWO I'm not sure that it is again true. ADS is more expensive than MWO.
Concerning CST, It is not for the same application. I prefer CST than HFSS because it is easier to use. The results are very good even in millimeter frequency. It is like all simulators, you can obtain what you want if you don't use it like with little knowledge. (see benchmark on CST site).
regards
Greg

Hi Ppl,
I'm working with @DS,Son,Ie3d and HFSS (for RF ICs)
And always in contact with their support
The bottom line is, that for RF use, every Sim can be
fast & accurate if you are an expert in the specific Sim and
familiar with all the specifications of the Sim.
From my experience for good first order (even higher) results, easy layout drawing,and very fast results the RF mode engine of @DS is the best.And only that engine can simulate whole TX/RX chains
no other simulation would be capable doing since the required
RAM will be beyond 2Gb.

| ADS is good for planar simulations but nothing beats HFSS in 3D simulations.

RFIC or even MMIC designer will rarely if ever touch or have touched or know how to PROPERLY setup up HFSS or MWS simulation. The SETUP is the name of the game with the 3D solver (similar to planar tools too) and results may vary alot. Which tool one uses depends on the task one has to solve. MWO is very powerful and easy to use, ADS is even more powerful. BUT price tags differ hugely as well. Suppose one has a 3 designers and needs 3 seats. There is lots of cost involved with ADS - I know no manager that won't go for the cheaper tool that can do say 90% of what the other can do too. 90-10 rule is still alive.
On the other hand if one does need 3D IC simulation, one may well use EM3DS - a very good MOM tool that we use for layout simulation with thickness and all other crap included - that is a real 3D device. One may also use Sonnet or other EM tool if they don't need to worry about thickness effects etc. equally well with AWR, while going for ADS means either Momentum (good one, hands down,) or CST(good one, but for 35k will be underutilized) or go through export filtering.
To me the downside of MWO is EMSight. Too many constraints, and not able to handle many real world situations. Plus the grid nightmare.

I am using @DS and CST as well as HFSS. All programms are quite powerful. But it depends on your problems. For radiating structures the CST is very good and the results are excellent. I sometimes build antennas and compare the results with what I measured. CST is also very easy to use. The manuals are very helpful.
The @DS is better for planar structure but I often import the models from the 3D simulation. It taked a while till you know how to use it. It's very complex but not bad.
HFSS is ok.

hello
due 2 my experience in that field i tell u it depends man on ur application, 4 instance, ADS is the best for system level simulation, layout design and momentum analysis.
mws is the best tool yet suitable for 3D-EM analysis of planar structures.
AWR is intermadiate in my opinion.
goodluck !

| Hfss is strong in EM simulation, and ADS is good for most circuits and system design. I use them for my RF projects.

| I agree with consensus on MWO for beginner and moving up to @DS once you had learn your ropes. There some Ansoft tools too to consider, like Nexxim for circuit and of course HFSS. Cadence SpectreRF is very good for RFIC.

Hi,
In my case, I need to simulate antennas. I will try the free demo version of SuperNec from Poynting. I wonder if it exist any softwares then that. I need some suggestions beause I'm a beginner too. Once I'm familiare with the antenna part, I need to simulate the whole system. I mean the generator (transmitter or receiver) which related to the transmisson line and then pug to the antenna and see the results ( output results). Any suggestions will appericate.
Thanks,
Mica

I use Momentum in @ds 2003c for high frequency simulation. Compared to other simulators, I think Momentum has many advantages as following:
-- Easy to configure device structure. Structure can be easily configured and modified in substrate configuration.
-- Adequate accuracy, especialyy for single layer planar stucture.
-- Less simulation time than true 3D simulators, such as HFSS.
But because Momentum is only a 2D or 2.5D simulator, it's not very suitable for complex multilayer structure.
HFSS, which I'm learning now, is more difficult to draw structure and more complex to set boundary and ports, but accurater than Momentum. Just my opinion.

hi everyone,
I promote the HFSS 8.x, because HFSS 9.x need good performance PC and run slowly on the same case.
The @DS2003 is also good on the RF CKT simulation.

Why not try E(at)glew(at)re? it's a complete and fast and easy to use RF beginners and professionals.
You can prove and fast your designs much better than @DS and others. I think the suites' circuits fuction and filter fuction is No.1 in simulation.
I changed my soft from @DS to E(at)glew(at)re the first time I tried it.

Yes,
MWS has several dispersion models included for the Time Domain Solvers.
If you use the MWS freq. domain solver, you are not limited at all.

If I have to choose one of them ( CST MWS vs XFDTD) which do you prefere for a beginner and also, it can simulate a variety of antenna ( thin wire through complex sturctures). I will do design antenna. If you can choose, then list things which a software should for antenna design.
Thanks,
Mica
