For example, and we assume the Simulation Point is 90, then I start
simulating at instruction 90 * 100 million (9 billion) and stop
simulating at instruction 9.1 billion assuming a 100 million interval
size was used to create the simulation points.
How can I calculate when the interval is 250M: we assume the simulation
point also is 90. do I start simulating at instruction 90*100M or
90*250M?
