I have an application on an SPC58 that I really want to know more about. But unfortunately; it’s a dual core with lockstep. So if it could be done; I think that automatically double-pluses the budget.

Don’t need lasers for that chip, it absolutely can be done with enough time and effort.

Don’t let fancy language like lock-step dissuade you from trying. The people who configured that chip also have to have done their job perfectly or it might still have a way in!

It’s two power supplies, two cores, lockstep, and an HSM they hype up… I’m pretty sure I would need two emps and a high precision rig at the minimum.
