2.all_fanout/all_fanin

下面给出一个all_fanout、all_fanin的用法实例

cop [remove_from_collection -intersect \
[all_fanout -flat -from xx_clk -trace_arcs all] \
[all_fanin -flat -to xxx_reg/Q -trace_arcs all]]
 
 
proc cop {collection} {
    foreach_in_collection tmp $collection {
    set full_name [get_attri $tmp full_name]
    echo $full_name
}
