Was FORTRAN buggy 4337

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 piece of gear available as a model?

But how do you verify that the emulator equals the real hardware at all times? This is what Charlton seems to be skipping from his posts in this thread. YOu have to have the real hardware made, preferably from the the manufacturing line, and installed and up and running for YOU to compare.

Sure. That's a reasonable staging of production of the software. But note that all of the stuff has existed before. I've been trying to talk about hardware that doesn't exist yet...that development project.

Yup. This approach of the process was getting developed from scratch in the 70s. I think this was a side effect of CAD. What's concerning me now is that the notion that the emulator must equal the hardware is getting usurped by the notion that the hardware must equal the emulator. It implies that hardware is no longer getting innovated. That dooms the computer biz.

I would rate this as a high level security bug.
