How to replace only a pattern in a set of labels

ssram

For example, if i've a bus label like bg_n<0>, bg_n<1>, bg_n<2>, what can i do to replace the n in those to p so that my new labels will be bg_p<0>, bg_p<1>, bg_p<2> ? It becomes really difficult sometimes changing these manually when there are over 200 pins in the custom layout. Anyone has a script to do this?

    I will try to merge this post with the other thread.

  • If it's just the labels you want to change, something like:

    origPattern=pcreCompile("bg_n")
    cv=geGetEditCellView()
    foreach(shape cv~>shapes
      when(shape~>objType=="label" && pcreExecute(origPattern shape~>theLabel)
        shape~>theLabel=pcreReplace(origPattern shape~>theLabel "bg_p" 0)
      )
    )

    Note that this doesn't try to be selective - so if you have labels which are "abg_ntest" then that would also get replaced to be "abg_ptest". You may want to change the pattern on the first line to "^bg_n<" and the replacement on the last (non-parenthesis) line to be "bg_p<" if you want it to be more anchored.
