More Information
Summary:The invention discloses a multi-driving-capability integrated circuit standard unit layout migration method, which comprises the following steps of: taking a completed layout of a standard unit with certain driving capability of an integrated circuit as a reference layout, and taking to-be-generated layouts of the standard units with other driving capabilities as target layouts; gradually obtaining a target layout of the standard unit under the required driving capability according to the reference layout; dividing the reference layout and the target layout into four types of information: geometric information of layout, topological information of layout, geometric information of wiring and topological information of wiring; a layout layout is obtained by migrating layout information, geometric transformation between layouts is calculated, a Steiner tree is generated, wiring grid planning is carried out, a final wiring layout is obtained through a constrained A star algorithm, and automatic layout and wiring
