As part of my EOL testing I’d like to get a measurement of the deadtime to check for any issues. Is this something that can be output by the half-bridge block in sub-cycle average mode?
The half-bridge block does not output the dead-time. It may be possible to estimate the dead-time by looking at the PWM Capture output signals if they have an appropriate resolution.
The simplest approach to get an estimated dead-time (assuming a constant frequency and constant dead-time) would be to look at the average of the summed half-bridge gate signals. See the attached screenshot for a suggestion.
If there is a variable frequency or variable dead-time element then one could implement a C-Script to detect the the turn-on and turn-off signals to compute the dead-time. This is more involved than the simple approach suggested above.

Thanks Bryan, this works good enough for my purposes.
