线负载模型定义了单位长度的电容、电阻和面积,扇出负载与线长的对应关系(fanout_length),线性近似斜率(slope)。当扇出负载超出定义在fanout_length上的最大值时,互连线长度可以用斜率slop值根据已有的fanout_length线性化近似得到。wire_load定义列出如下: wire_load ( "reference_area_2500000" ) { resistance : 0.00...

时序分析基本概念介绍<wire load model> 今天我们要介绍的时序分析基本概念是wire load model. 中文名称是线负载模型。是综合阶段用于估算互连线电阻电容的模型。 下图就是一个比较常见的wire load model。该模型包含了互连线长度,电阻,电容,面积等信息。在综合阶段计算时序时,工具从lib文件中得到cell的延迟,而互连线...
