Abstract: Aiming at the isolation state detection of logic-unknown Programmable Logic Device(PLD), black-box detecting method is studied. By analyzing the PLD’s I/O structure, the principle of the pin attributes identification in course of detecting is expounded, and the performance of three types of identification algorithms is analyzed. For state-driven issues, the implementation idea of existing driven algorithms is elaborated, the space complexity is analyzed and the time complexity of state search as well as transfer path length is analyzed. Then the problems needed to focus on in the following study are raised.
