The following example shows how to apply the pt_dont_use user attribute to a set of
library cells. You must define the user attribute first:
pt_shell> define_user_attribute pt_dont_use\
-quiet -typeboolean-classlib_cell
You can use the attribute directly with the set_user_attribute command, or, for
convenience, you can define the following procedure:
proc set_pt_dont_use{lib_cell}{
set_user_attribute \
-class lib_cell\
[get_lib_cell -quiet$lib_cell]\
pt_dont_use true
}
Now, you can use this procedure to apply the attribute:
set_pt_dont_use {lib/CLKBUF*lib/CLKMUX*}
