No, the chip design is not software that can be extracted. It is a set of behavior at the external pins that is derived from a cascade of internal logic. It can be very difficult to figure out the internal structure just from external behavior. The way chip reversing is done is to depackage and image the chip. Then identify major features (ALU, register file, etc.) Image recognition software (similar to OCR) can help these days in reconstructing small areas of chips. But it's still too complex for larger chips. Here is an example: http://siliconzoo.org/ -- Nate Message was sent through the cbm-hackers mailing listReceived on 2010-07-26 17:00:03
