Usage
get_rtl_fanouts [-inverting_paths] [-non_inverting_paths]
Options
-inverting_paths: Only follow inverting combinational paths
-non_inverting_paths: Only follow non-inverting combinational paths

or collection)
Description
Returns a collection of fanout pins starting from the in the design.
When the -non_inverting_paths option is used, get_fanouts does not follow any paths that include an odd
number of inverters. Similarly, when the -inverting_paths option is used, get_fanouts does not follow any
paths that include an even number of inverters. Both the -non_inverting_paths and -inverting_paths
options are mutually exclusive.
The filter for the collection is a Tcl list of wildcards, and must follow standard Tcl substitution rules.
Example
set fanouts [get_rtl_fanouts $item]
foreach_in_collection fanout $fanouts {
lappend fanout_list [get_rtl_pin_info $fanout -name]
}
get_rtl_fanouts inst1 -non_inverting_paths
