How to count number of paths in RTL-compiler group?

dkos

 Hello all!

 Does anybody knows how to count number of paths in group, created by 'path_group' command? Or, at least, determine is group empty or not?

Thanks, dkos

    Hi dkos,
     
    A little bit dirty, but it should work:
    report timing -paths [eval [get_attribute paths <path-group name>]] > xyz
    set TMP [exec egrep "slack|No paths found" xyz]
    if {$TMP eq "No paths found"} {
       ...
    }
     
     
    I have to use "egrep", because "grep" would give an error if it wouldn't find anything, while with egrep either "No path found" or "slack" will match.
    I hope this helps!
     
    Regards,
    Johannes
