Abstract
In a method for managing design data regarding an electronic circuit in order to design and analyze the electronic circuit, the design data is arranged according to a hierarchical-layer module structure. The design data in each of hierarchical layers of the hierarchical-layer module structure is divided into objects. The objects together for each of the hierarchical layers are connected together and the objects are connected together over the hierarchical layers. The design data including design data having different items and design data having different data lengths is integrally managed.
