set_wire_load_model “wlm_cons” -library “lib_stdcell” 当一个网络跨越了设计层次(hierarchical)的边界时,可以基于线负载模式(wireload mode)将不同的线负载模型应用于每个层次中网络的不同部分。这些线负载模式是:a)top, b) enclosed, c)segmented。 1) top 该模式下,hierarchy结构中所有nets都继承top...
set_wire_load_mode 小结 1.总述 在绕线之前,比如综合阶段为了估算线延迟的数值在lib中会提供不同的线延迟model,因此以上两个命令的主要作用就是估算线延迟所带来的影响。简言之,set_wire_load_model用于指定估算线延迟时所选用的模型,不同的模型所对应的计算原理略有差异,具体分析参考Foundry spec。set_wire_...
你可以设置一个库中最大的WLM，把auto select关掉.dc_shell auto_wire_load_selection =false一般库里面会带有不大准确的WLM，对应不同面积 更精确的要在生成版图之后提取， 得到CUSTOMER WLMSet_wire_load <wire-load model-mode <top|enclosed|segmented向DC提供wire_load信息，...
时序分析基本概念介绍<wire load mode> 今天我们要介绍的时序分析基本概念是wire load mode。中文名是线负载模型的选择方式。 对于跨越边界的net,我们除了选用合适的wire load model以外,还需要选择合理的wire load mode. wire load mode主要有三种top、enclosed 和segmented。这三种模式所选取的wire load model方法有...
