    • A macro cell creating method capable of accurately calculating the delay values regarding input/output terminals of a macro cell and efficiently designing a high-speed macro cell. The macro cell creating method includes a first step for creating a frame of a macro cell based on a size estimate of a circuit, a second step for disposing provisional external input/output terminals on the frame of the macro cell based on input/output terminal information of the circuit, a third step for adding connection information of the provisional external input/output terminals with actual input/output terminals to circuit connection information, a fourth step for disposing basic function cells based on the circuit connection information, a fifth step for wiring the basic function cells, a sixth step for deleting wired lines between the provisional external input/output terminals and the actual input/output terminals, and a seventh step for creating macro cell layout data.
    • 一种能够精确地计算与宏单元的输入输出端子相关的延迟值并有效地设计高速宏单元的宏单元生成方法。 宏小区创建方法包括:基于电路的大小估计来创建宏小区的帧的第一步骤,用于基于输入/输出终端在宏小区的帧上配置临时外部输入/输出终端的第二步骤 电路的信息,用于将临时外部输入/输出端子与实际输入/输出端子的连接信息添加到电路连接信息的第三步骤,用于基于电路连接信息设置基本功能单元的第四步骤,第五步骤 布线基本功能单元,第六步骤,用于删除临时外部输入/输出端子和实际输入/输出端子之间的有线线路;以及第七步骤,用于创建宏单元布局数据。
