No but I'd feel more comfortable knowing that every software update has been tested against a hardware emulation that at least reproduced every form of hardware failure that could be reproduced and that the software behaviour under these conditions was appropriate. This is one stage better than throwing the software at the hardware without being able to test the behaviour of the software against hardware failures until they happen.
IOW The test is the other way up - if it doesn't work on an emulator it shouldn't be let near the real thing.
Yes of course I expect testing against real hardware and when that causes different behaviour to the testing against the emulator I expect that to feed back into improvements in the emulator.
In fact AIUI aircraft software is likely to be tested against software emulations and then against hardware emulations in the form of simulators before it gets into a real flying plane.
But don't you see? In order to reproduce every form of hardware failure of a piece of gear, you have to have the real physical...
They can also shorten the development cycle of software and improve the regression testing of that software.
