Anyway to find output ports on a clock in tcl?

Thanks for the pointer on this. I found that I first had to put some timing on the output ports first:

set_output_delay 10.0 -max -clock  -add_delay 

This gives all sorts of expected warning messages which I'm ignoring, but it allows:

set myPaths  -to  -npaths 1000]
foreach_in_collection path $myPaths {
    puts 
}

Unfortunately I'm stuck as it only returns a list of nodes (the ports?)

Now, if only set_output_delay would accept nodes...
