simultaneously replace library name and cell name of cells in ADE schematic

In ADE schematic, you can replace library name or cell name of cells by Edit -> Replace. But you cannot replace both library name and cell name simultaneously.

For example, we want to automatically replace cells with lib name of hiscs40ulph07svt40_ana and cell name of xxxSVT40_ana to cells with lib name of hiscs40ulph07svt40 and cell name of xxxSVT40.

	Old Name	New Name
Lib	hiscs40ulph07svt40_ana	hiscs40ulph07svt40
Cell	xxxSVT40_ana	xxxSVT40

The following skill script provides this function.

procedure(CCFreplaceStdCellsPat(@key 
        (cvId geGetEditCellView()) 
        (fromLib "hiscs40ulph07svt40_ana") ;old library
        (toLib "hiscs40ulph07svt40") ;new library
        (pattern "40_ana") ;comment this if the cell name keeps
	(with "40") ;comment this if the cell name keeps
      )
  let((newCellName pat)
    pat=pcreCompile(pattern)
    foreach(instHeader cvId~>instHeaders
      when(instHeader~>libName==fromLib && instHeader~>instances
        newCellName=pcreReplace(pat instHeader~>cellName with 1)
        dbSetInstHeaderMasterName(
          instHeader
          toLib
          newCellName
          instHeader~>viewName
        )
      )
    )
    t
  )
)

Save the above skill script as replace_lib_cell.il and load it in CIW by

load("<path>/replace_lib_cell.il")

Then run the command in CIW (with the schematic open and in the current window):

CCFreplaceStdCellsPat()

Don’t forget to hit Check and Save after replacement. You can also globally replace devices, e.g. form “LVT” to “SVT”. You might also want to change the library names it is looking for, so you could do:

CCFreplaceStdCellsPat(?fromLib "origLibName" ?toLib "newLibName")

There’s also the ability to pass ?cvId so it doesn’t have to be a schematic open in a window (it could have been opened with dbOpenCellViewByType), or to use a different suffix via ?suffix.
