The last error message was "Analysis: Time step too small; initial timepoint: trouble with u3:40ua-instance j:u3:12" I tried the following as it was recommended on a forum But now I'm not getting the desired results. My circuit is shown below, it is a biasing circuit of an RF ...

Time step too small; initial timepoint: trouble with node "u1:21"add the UIC option to skip finding the initial operating point, and you get: Code:[Select] Time step too small; initial timepoint: trouble with node "u1:30"which IMHO indicates something iffy about either the model's circu...
appear. We do that now, and firstly select "transient" and enter a stop time of 10ms. Click OK. PLace the now attached command on the workspace. Again select edit simulation and this time select "AC Analysis" Set the options as follows, click OK and drop the new command onto the...
Analysis: Time step too small; time=1.6021e-005, timestep==1.25e-019: trouble with node "u1:30" I believe this to be a comparability issue, since it is commented in the model: "Use PSPICE (other simulators may require translation)" My question is: how should the model be modified...
