This paper proposes a new approach for the development of a module generator that can parameterize both the size and the structure of layout. The proposed method acquires a design procedure from the design process of a designer, and reuses it to synthesize new layouts with different input parameters that affect the size or the structure of layout. In this method, a designer creates a module layout on a layout editor instead of writing a program. From his design process, a procedure to synthesize the layout is automatically derived. Then, it is generalized so that it could be valid under different values of input parameters. The generalized procedure is independent of design rules, and is capable of synthesizing error-free module layouts of different size and structure. Also, the procedure includes designer's requirements on how the layout should be designed. The experimental results of applying the approach for developing generators of analog device components show effectiveness of our approach.
