Reverse engineering is a process that converts low-level description to high-level one. In this paper, we propose a hybrid approach consisting of structural analysis and black-box testing to reverse engineering on combinational circuits. Our approach is able to convert combinational circuits from gate-level netlist to Register-Transfer Level (RT-level) design accurately and efficiently. We developed our approach and participated in Problem A of the 2022 CAD Contest @ ICCAD. The revised version of our program successfully converted most cases and achieved higher scores than the 1stplace team in the contest.
