I think you are confusing things a bit. If you have computing hardware 
mocked you are doing simulation and the time is simulation time. If the 
peripheral hardware is real or partially real it is hardware-in-the-loop 
simulation (HIL). HIL is usually real-time because. What people are 
saying is that HIL is much more cost efficient developing platform than 
some embedded board. Furthermore Ada is ideal for HIL because Ada 
software is portable. So you can develop almost everything on the PC and 
test almost everything in the loop. Then if some hardware (except the 
board itself) is too expensive or difficult to use, it can be simulated 
(mocked) in turn. Which is especially important when you want to test 
some catastrophic or improbable scenarios.
