Hardware verification has become challenging due to growing complexity of todays designs. We aim at assisting verification of hardware intellectual properties (IP) at register transfer level by means of data abstraction and static formal analysis techniques. We intuitively define the "Control". The proposed definition was envisaged for separating Control and Data, independent of the subjective choice or the specific syntax. We have worked around a few semantic issues of the definition and demonstrated by reasoning. A control-data slicing algorithm is proposed to split...
