This is for information only.
Since I do not personally know these people I cannot vouch for the quality of the webinar. But I have interacted (fruitfully, I must add) with High Rely in the past and the Rational Software is good, and the fact that the webinar is free, you might want to give it a shot.

Sec 4.4.3 of DO-178B states that "Testing may be performed using the target computer, a target computer emulator or a host computer simulator" and further states that "The emulator or simulator may need to be qualified as described in subsection 12.2" .I think this answers your question...

I have query on SUT?
As per Do-178B Section 6.4.1, SUT can also be performed on Host Computer Simulator for credit. I am not sure on this statement!. My understanding is that SUT need to be performed only on Emulator/Evaluation boards to get credit.! If we perform SUT on Simulator do we need to get tool qual for that?
