Abstract
A circuit design method and a circuit design apparatus of this invention allow a judgement from a broader view based on high-level design information inputted upon a logic design to determine a rough packaging design. A rough placement position of a function block cell, which can configure a circuit that is an object of the design, unit on a circuit is determined on the basis of abstract circuit information in an abstract level higher than that of packaging design basic cell obtained in a logic design. On the basis of the rough placement position and the abstract circuit information, the function block cell is two-dimensionally developed into the packaging design basic cell, and a packaging design of the circuit that is an object of the design is performed. The method and apparatus of this invention is applicable to a design of a circuit such as an LSI, a PWB, etc.
