I love having this simulator. It is a great learning tool. When running Run Time Domain Simulation, I specified that the first second be plotted, but it only graphs out to 100ms. What am I doing wrong? Please see attached screen shots. (Oops, can't find where I can attach screen shots of my settings and plot.) Thank you.

Here's an interesting finding. I have 2 time switches in my circuit. One activates at 0.05s and the other activates at 0.1s. I just now changed the 2nd one to activate at 0.07s and now the graph ends right before 0.07s. Ugh. I really wanted to know what happened when the 2nd switch activated.

@DWC,

Welcome to CL.

Can you make your circuit public so we can have a look at it and see what might be the problem.

In the meanwhile some possible help:

I suspect you have either a time step problem and or a convergence problem.

Switches in CL change state in a very short time step (possibly zero: it's not publically documented). Simulators don't like that: they have to do a lot of sums to work out what happens after the discontinuity that such a fast event represents.

Hi Signality, Thank you for your reply! I understand. Here is my circuit: https://www.circuitlab.com/circuit/g9427w/highside-n-mosfet-bootstrap/ Thank you!

@DWC,

Had a quick play. Changed time steps, removed the MOSFET, 100pH inductor and 100uF cap. Connected any floating nets left over to ground or each other by 100R resistors and added 1mR to each switch ON resistance.

Still won't run after 0.07s.

No warnings, no error messages.

Looks like a bug in CL to me.

Signality, Your reply was a big help to me. I see that throwing 2 switches at the same time caused the problem. So I updated the circuit. See the fixed (and working) circuit here: https://www.circuitlab.com/circuit/mcpy72/fixed/ Thank you Signality!

Hi Signality, Wow, pretty cool circuits. I'm learning a lot about the use of CircuitLab thanks to your help!
