I have a question about ADS smilation， can someone help me?

When I do Transient simulate using the ADS, it always said that the iternal timestep *** to small at time ***, and I can't find the answer from the help files of the ADS,can someone help me to solve this problem? Thanks a lot

I think (but I'm not sure) that is a convergence problem.
What kind of circuit are you simulating?
Try to help the simulator giving some known voltage.
I hope it can help.

p.s. @DS transient is not so good...

can u send the simulation files
to check it

It is a convergence problem, you can try to set some initial points by nodeset component, or change the error method for transient analysis or change the tolerance for transient analysis. If suitable you also can simulate the circuit in frequency domain then use fft to trans to time domain.

it is convergence problem. For oscillator you need to set the initial conditions.
