Extract IC code from its embedded and encrypted memorizers like FLASH & EEPROM can have a great variety of methods, which include the non-invasive IC extraction, semi-invasive IC extraction which has both the cost advantage and shorter time cycle, and finally the most expensive and which has also been specified as the last method to overcome those difficult IC extraction is invasive one.

As one of the non-invasive IC extraction method, modeling attacks has played the role for a while since the day it has been invented and developed. So in order to research the effective measurement, it is critical to understand the code extraction details. In the optical light injection and laser scanning attack methods, IC cracker need to fully understand the operation process and principle in the semiconductor IC. And simulate this kind of IC code extraction will have a lot of restriction. Each step need to tackle with multiple aspects in the complicate system. And it could be pretty difficult to calculate a beam of laser affection on the IC extraction. But for a small part of transistors, it is possible to make the simulation. In the TCAD software, and can simulate ion radiation effects for the semiconductor IC. But this software is just too expensive and too complicate, so we should choose another one tool name DIODE-2D.
