report_inactive_arcs
[ instance_or_port_list ]
[-delay_arcs_only | -check_arcs_only]
[-type disable_type ]
[-include_net_arcs]
[-include_when_cond]
[-view viewName ]

这个命令可以报出design中inactive的timing arc的具体信息，包括delay arc和timing check arc

instance_or_port_list 指定想要报出inactive arc的具体instance和port list，默认会报出整个design的inactive arc

-delay_arcs_only 只报出disabled的delay timing arc. 包括combinational timing arc, edge timing arc, Preset and clear timing arc, Three state Enable&Disable timing arc

-check_arcs_only 只报出disabled的check arcs. 包括setup timing arc, hold timing arc, Recovery timing arc, Removal timing arc, width timing arc

-type 只报出符合该类型的disable arc

check_types: 报出以下几种check type的disable timing arc. Setup, Hold, Recovery, Removal, Pulse Width, Clock Gating Setup, Clock Gating Hold, Clock Gating Pulse Width, Clock Period, Skew, Clock Separation, NoChange.

conditional_disable: 报出是由于指定when condition而disable的timing arc

const: 报出是由于constant value而造成的disable arc

disable: 报出由于使用set_disable_timing而造成的disable arc

library_disable：报出由于library中disable掉的timing arc, 比如说一些异步逻辑的timing arc等等

snipped：报出由于timing loop而disable掉的timing arc

-include_net_arcs：把net上的disable timing arc也报出来

-include_when_cond：把when condition的timing arc也报出来

-view：指定analysis view
