set_verification_priority,可以将某些design(reference)的verify优先级调高,从而在formal verification的verify阶段,更容易比过(可以用来解决abort的问题); set_multibit_options,设置多比特DFF的选择标准,比如设置为“timing_driven”就是时序驱动的; set_clock_gating_style,来设置ICG的insert标准; set_operating_conditi...

之前,我们应先使用命令 set_clock_gating_style 来指定要插入门控时 钟的结构。且此处勾选Gate clock 选项。 点击OK 执行Elaborate。执行结果如下图: 当控制台出现 Presto compilation completed successfully. 表示 elaborate 成功。点击create symbol view 所指向的按钮可以看该电路 ...
