collection

Have a look at the comments section of this blog entry -- it covers that subject I believe:

If you have multiple paths in the collection you can iterate through them with "foreach_in_collection". For example of you wanted to print out how many timing points were in each of the first 10 worst paths in the design you could do this:

set c [report_timing -max_points 10 -collection]
set count 1
foreach_in_collection path $c {
set timing_points [get_property $path timing_points]
puts "Path $count contains [sizeof_collection $timing_points] timing point(s)"
incr count
}

 hi bob,

        thanx a lot...I think it will do for me
