Does DO-178C require object code structural coverage?

If you are developing software to Level A for DO-178B/C, your code has to undergo extremely rigorous structural coverage analysis for the purposes of certification. This includes examining both source and object code.

What are the implications of multi-core devices on code coverage?

The use of code coverage (also called structural coverage analysis or SCA) when testing safety-critical systems is widely established. For example, in the aerospace domain, the DO-178B/C guidance requires specific types of coverage testing to be carried out. The depth of coverage testing required depends on the system's safety level, with the most critical requiring the use of modified condition/decision coverage (MC/DC).

Automatic generation of MC/DC test cases - a complete waste of time?

Blindly generating tests to produce 100% MC/DC coverage is not the way forward. The bottom line is you don’t actually learn anything new. Can a test vector generation tool – which only generates test vectors for code that is uncovered by the existing test suite – be useful in a safety critical context?
