I'm designing an H bridge driver in LTSpice 17.0.19.0. The bridge is working very well, but LT refuses to bring up the current meter or thermometer icons for just two components in the entire circuit, the transistors in the upper left quadrant. The quadrant must be delivering current, since the load current and waveform are as expected.
I've tried deleting and reinstalling the components, which didn't help. I don't understand LT internals well enough to even hypothesize problems and solutions.
Hoping this is a known bug. It's not holding me up just now, and if needed I can put in 1 milliohm resistors to check branch current. But it is a worry. What other surprises might LT have in store for this circuit? This must be my twentieth design at least, and this is the first time I've seen this.
