Automating Layout Cell Updates Using SKILL with Cell List from File

AR202509246930
We’ve received updates to existing layout cells — for example, changes in pin coordinates and PR boundaries. A function has already been developed to apply these updates for a single cell. However, since there are around 100 +existing cells, manually opening each layout and invoking the function is time-consuming.
To streamline this, the goal is to automate the update process by reading the list of cell names from a .txt file and applying the update function to each cell in the background, without manual intervention.

let say my developed function is layoutupdate() and I'm using the Virtuoso Cadnece IC 23.1 version

Any guidance or examples on how to implement this in SKILL would be greatly appreciated.

    Something like:

    chomp=pcreCompile("\\s*$")
    prt=infile("cellnames.txt")
    while(gets(line prt)
      ; remove trailing whitespace/newline
      cellName=pcreReplace(chomp line "" 1)
      layoutupdate("mylib" cellName ...) ; whatever arguments you need
    )
    close(prt)
