Method and apparatus for modifying flattened data of designed circuit pattern |
摘要 |
Grouping is performed by classifying the data of features having same shapes and sizes in the same layer into the same group. In the grouping, a feature size having lengths of two adjacent sides of a rectangle inscribed by the feature is obtained to attach the size to the feature data, and if feature data has the same kind, layer and size, the same group name is attached to the feature data. When a feature data is selected by an operator to modify it, the other feature data having the same group name are automatically modified in the same manner. |
