Method of generating dependency specification file capable of reconfiguring function block of soft IP and recording medium storing codes embodying the method

Provided is a method of generating a dependency specification file of a soft IP comprising, extracting constituent element information by parsing a netlist file of a soft IP and designating an instance name and a component name to input and output ports and function blocks which are constituent elements existing in the soft IP, converting the constituent element information to a vertex for each constituent element, indicating a dependency specification between the vertexes for the respective constituent elements, and generating a dependency specification file by converting the vertexes for the respective constituent elements and the dependency specification that the netlist file of the soft IP contains to an electronic circuit design language file, and outputting the dependency specification file.
