Re: struggling

Aditya, thanks!

I'll try your suggestion as it looks very clean and short.

In the meanwhile I found this to work too:
foreach_in_collection clk1 ${clk_lst} {
  foreach_in_collection clk2 ${clk_lst} {
     set clk1_name [get_object_name $clk1]
     set clk2_name [get_object_name $clk2]
     if { ${clk1_name} != ${clk2_name} } {
         echo "Information: Setting false path from ${clk1_name} to
${clk2_name}"
         set_false_path -from ${clk1} -to ${clk2}
     }
  }
}
