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...
I'm working on an audio power amplifier. I recreated the schematic from the internet in LTSpice and now I'm getting error: "Analysis: Time step too small; time=1e-006;timestep=1.25e-019;trouble with bzx84c15l-instance d1". This is the first time I'm using this program and I hav...
I'm simulating a circuit in LTspice with third party spice models aaded to it. I encountered several errors but got them solved with the help of many forums. The last error message was "Analysis: Time step too small; initial timepoint: trouble with u3:40ua-instance j:u3:12" I tried...
It's LTspice nebulous way of indicating that it's having trouble simulating the circuit. The message usually doesn't point to anything specific except a point in time. Check the circuit structure. Check that values are reasonable, etc. Check node voltages and currents. You can try looking at...
Now we wire it up using the <wire> symbol from the top line. This looks like a pencil. Click it and you have a crosshair cursor appear. Move that over a component node and left click. Then drag the wire up/down/left/right etc left clicking each time you want to change direction...
