Well the big problem with this is there is no easy test to define whether a PIC is actually "functioning", to do it right you'd have to test every opcode, every program memory location, every ram location, every peripheral, it is a huge undertaking, and that is ignoring boundary voltage and temperature conditions. The fact that an I/O pin is still toggling isn't of much use. I think that is why Olin is so adamant that this whole thing is useless to even academically look at.
