I'd be careful with EMI/EMP based testing, if it's latching up one line or flipping one bit, it's probably also doing it to a ton of lines/bits. I'm guessing here but based off my experience with such things, I'd expect it to be more likely to latch up whole busses and generally just crash the system than trigger anything ECC could report unless you had a very repeatable setup you could ramp up in a very controlled fashion. The mode of action here is you're producing a very wide band pulse but it's most strongly couple to the PCB traces long before anything within the chip itself. Guessing again but when people are using this to hack chips, they're probably just causing voltage swings on the power traces that are effectively voltage glitching the chip. The problem is you're over volting the part rather than under volting it which may cause permanent damage.
