Does diverse "compilation" not address this problem in the hardware space? There are multiple sources of 555 timer equivalent and replacement chips for example: multiple fabs implementing the same spec should get results which are equivalent. Though I suppose you can't really verify an unintended excession of function, which is really how you hide malicious behavior (unless you did something like space missions do where you have multiple systems running in lock-step and having their results cross-checked).
