One of the interesting features of the test platforms that are used, is the possibility to slow down the chip clock. The operator of the machine can choose to go from billions of ticks per second to a single tick, allowing human eyes to follow what is going on. With the same ease the clock can be stopped altogether. If needed, that gives the engineers the luxury to be able to stare for two hours at a situation that would normally be over in a fraction of a nanosecond.
