Just have it fail after a certain date or in response to a particular
message, then. ;-)

Also:

"In addition to the Ivy Bridge processor, the researchers applied the
dopant technique to lodge a trojan in a chip prototype that was designed
to withstand so-called side channel attacks. The result: cryptographic
keys could be correctly extracted on the tampered device with a
correlation close to 1. "
