And it never will be. In aviation we certify three things: aircraft, engines and propellers. Everything else is at best certifiable, i.e. can be integrated into a product to be certified assuming all deviations, restrictions, caveats etc are considered when doing so.

Also, tools follows DO-330 and are qualified. It's their output that should comply with DO-178.

Sure, yes, I always end up saying “certified” instead of “qualified” for some reason. Thanks.
