Description |
Returns information about the specified edge (referenced by edge ID). Edge ID's can be obtained by Tcl commands such as get_node_info <node_id> -synch_edges. The "-type" and "-name" options exist only to keep the interface compliant with the get_object_info command. The "-type" option always returns "edge", while the "-name" option always returns an empty string. The "-delay" option returns the delay associated to the edge. Use -max/min and -rr/rf/fr/ff options to specify the type of returned delay. One of the -max/min options must be specified. One of the -rr/rf/fr/ff options must be specified. The -hslp option returns the HS/LP setting associated to the edge. The -unateness option returns the unateness associated to the edge. |
