Basically splitting the trusted circuit and testing the parts separately. This requires a trusted master circuit, but it can be arbitrarily small.

But what if the malicious code is time activated? (just an example)

This is actually addressed in the paper. Basically you can use testing to detect the timebomb, up to a negligible probability.

This paper is approachable, it's understandable without too much background if you're interested in the topic.
