怎么可以把list反向输出

请教一个问题，all_fanout -from xx输出是A，B ，C，D的顺序，怎么可以实现输出是D,C ，B，A？

all_fanout returns a collection, not list.  
If you only care about the name of the objects in the collection, you can convert all_fanout output into a list first.
Once you have a list, it's easy to use lreverse to change the order of the list.  

Example:
set myList [get_object_name [all_fanout -from u_digcore/u_registers/rg_config0_r_reg_0_cn/Q -endpoints_only]]
puts $myList
puts [lreverse $myList]

If you want to reverse the order of the objects in a collection, it takes a few more lines.
