Yes, or pretty close to it. What we don't know how to do (AFAIK) is do it at a cost that would be acceptable for most software. So yes, it mostly gets done for (components of) planes, spacecraft, medical devices, etc.
Totally agreed that most software is a morass of bugs. But giving examples of buggy software doesn't provide any information about whether we know how to make non-buggy software. It only provides information about whether we know how to make buggy software—spoiler alert: we do :)
