TimeQuest set_false_path Command

You can use the set_false_path command to specify your design's false paths (i.e., paths that can be ignored during timing analysis). The following list shows the the available options for the set_false_path command:

set_false_path
   [-from <from list>]
   [-to <to list>]
   [-thru <thru list>]
Table 1 describes the options for the set_false_path command.
Table 1. Options Description for set_false_path Command

When the objects are timing nodes, the false path only applies to the path between the two nodes. When the object is a clock, the false path applies to all paths where the source node (for -from) or destination node (for -to) is clocked by the clock.
