The ExcludeNets command excludes paths that contain specified nets from analysis. If a net is selected, paths through that net are not analyzed. However, if no nets are selected, which is the default, all nets, except those you exclude with other path filtering commands, are analyzed.
This command is equivalent to the Path Filters 
Common Filters Exclude Paths with Nets menu command.
The syntax of the ExcludeNets command is the following.
ExcludeNets [net_name1 net_name2...]
Net_name1, net_name2, and so forth are the names of the nets to be excluded.
Abbreviate the ExcludeNets command syntax as follows.
exnet [net_name1 net_name2...]
Following is an example of the ExcludeNets command.
