regex - TCL for DC: regexp matching of non-standard hierarchical names -

i'm trying write automation scripts synopsys design compiler, have troubles following case:

i see there logic tie-off nets have following name:

dc_shell> all_connected foo_top/foo/foo_pin {foo_top/*logic0*} 

in script want detect pins connected logic tie-offs:

set connected_nets [find net [all_connected $pin]] foreach_in_collection net $connected_nets {      if {[regexp {.*logic0.*} [get_object_name $net]] } {           # skip pin because tied logic 0           continue      } } 

this matching never succeeds. works other pins , nets, fails on tie-offs.

i feeling has fact tie-off net specified * in name, i'm not sure how handle it.

what can overcome , able detect these tie-off nets?

thanks

if try invocation regexp {.*logic0.*} {foo_top/*logic0*} 1, it's not matching fails. seem command get_object_name doesn't return expect to.

as side note, regular expression {.*logic0.*} equivalent regular expression {logic0} purpose of determining presence of pattern. unless add kind of anchor, ^ or $, regular expression matching adds implied .* either end of expression provide.

on other hand, variants not equivalent when capturing match:

set fbb foobarbaz set pat1 bar set pat2 {.*bar.*}  if {[regexp -- $pat1 $fbb] == [regexp -- $pat2 $fbb]} {puts "the same"} # => same  set cap1 [regexp -inline -- $pat1 $fbb] set cap2 [regexp -inline -- $pat2 $fbb] if {$cap1 ne $cap2} {puts "not same: $cap1 vs $cap2"} # => not same: bar vs foobarbaz
