I did a mistake in typing "under
stand", it was "I have under
stood", just a little mistake because I was tired and because English (blind in catching errors at the first sign) is not my first language, you can still understand the meaning, but imagine if you were blind in the source code, and this mistake reacts in the worst way during abnormal working: mission failed, everybody dies
And then they wonder why their product quality isn't that good
the "quality" implies how deep you know what your source code does, in this case we MUST have a dynamically coverage (->VectorCast) covering everything deeply within normal and abnormal working condition
we have to run the source code within a lot of test benches (described by ATP&ATR), probing stimulus from the outside (there is an hardware equipment for that) , and verify that every statement is covered in the reasonable way, with manually justifications in case of need ("unsafe code, defensive code, etcetc")
In short, the more I work with them, the more It does make sense
