there are many clocks on my design
clk0 - clk50

so i want to set_false_path between all clocks

set clock_list [list clk0 clk1 .. clk50]
foreach each_clock1 $clock_list {
foreach each_clock2 $clock_list {
if { $each_clock1 != $each_clock2 } {
set_false_path -from [get_clock $each_clock1] -to [get_clock $each_clock2]
set_false_path -from [get_clock $each_clock2] -to [get_clock $each_clock1]
} else {
}}}

and now, how to unset false_path already defined
and how to make some kind of 'set_true_path' between clocks

Hello Billylee,

To undo a set_false_path command, use the reset_path
command with similar options. For example, enter

dc_shell> set_false_path -setup -from IN2 -to FF12/D
dc_shell> reset_path -setup -from IN2 -to FF12/D

Regards,
