摘要:
In a hierarchical semiconductor digital unit comprised of a plurality of macro functional logic blocks, each of said macro functional logic blocks comprised of a plurality of leaf cells, each of said leaf cells accessed via an input terminal and an output terminal, the improvement wherein locating each input terminal provides access to a single leaf cell at a legal location proximate the leaf cell to which the input terminal provides access.
摘要:
A method, system, and computer program product for spare circuitry distribution in an integrated circuit design are provided. The method includes receiving design data for the integrated circuit design. The design data includes descriptions of spare circuitry and physical area available for circuitry placement. The method further includes determining target placement locations for the spare circuitry, where the target placement locations create a balanced distribution of the spare circuitry throughout the physical area available for circuitry placement. The method also includes shifting the location of the spare circuitry from each target placement location towards a nearest clock block within the integrated circuit design, resulting in an updated integrated circuit design. The method additionally includes outputting the updated integrated circuit design.
