simulate coupled oscillators?

Hi,
anybody know what kind of simulator can simulate coupled oscillators? (or circuit with oscillator and independent source like sine wave source?)

I tried spectreRF but the PSS analysis just can't converge. And the documentation says it's only made to simulate more than one tone mixed together...

Is ADS able to do it?

Thanks a lot!

what do you mean by coupled oscillaotr is it two cross coupled oscillator to generate the quadrature..
or coupled oscillator one like "MENTIS" (hope that i spell it correctly") type...
what the other independent source di doing in this coupled oscillator.

yes pss doc says that you cannot simulate the autonomus circuit with driven source...
may be you can try making the signal as large signal in the design in the pss analysis and checkl whether it is converging or not...

In fact coupled oscillators could be simulated in SpectreRF with a little bit take care. In additional to, ADS can simulate these kind of oscillators. But regarding to my past exprience, Ansoft Designer is more powerful in oscillator analysis and simulating.
I have attached a document about on those, I hope it may help you..
