Hi, I just fixed the displayed value for now, but later we can change it so you can create transmission lines with a specified length (instead of specifying delay).

I don't understand the question. You need help designing a circuit? Or you're having trouble with the simulator?

Is that a circuit you found somewhere on the internet? where?

I'm having trouble finding any information about PNP optocouplers. Do you have a particular device in mind, so I could check out the datasheet?

hmm, if so, then that neonbulb.sub model doesn't look sufficient.

Yes that looks like a bug, caused by roundoff error if I had to guess.

The simulator doesn't think one of the inductors has a current path, so it zeroes out the current. The other inductors don't count as a current path because their currents...

Here is a current-limited DC source with max voltage of 30V and max current of 8 A (which limits power to 240 W). The resistor is just a test load....

Well, you can hide the labels by unchecking Options->Show Values.

Apparently the voltmeter doesn't do a good job of RMS averaging if the waveform is not a sine wave. If you view it in scope and select "show RMS average"...
