Change layers automatically with an skill function

 Right now I am using Find/Replace function manually and is working but when I need to change many layers then it is not very nice to do it in this way.

cv=geGetEditCellView()
LP=car(exists(lpp cv~>lpps LP~>layerName=="M2" && LP~>purpose="drawing"))
LP~>shapes~>layerName="M3"

Of course, you'll need to do it in the right order (don't do M1 to M2, then M2 to M3 because all the M1 will also end up on M3).

 Hello Andrew,

Thank you very much for your quick response.

I tryed what you said but I get a warning: illegal left hand side of the assignment operator.

It does not do the conversion properly because I have some layers that have not been change. Can this be because I have some guardrings that have metal 1 inside. This script does not work with the ROD multipart paths?

THank you very much

Sorry, I typed it too quickly (I didn't test it) and made some typos - so here's a correction:

cv=geGetEditCellView()
LP=car(exists(lpp cv~>lpps lpp~>layerName=="M2" && lpp~>purpose=="drawing"))
LP~>shapes~>layerName="M3"

As for ROD objects (multi-part paths), if the shapes is a subShape of the ROD object, then it will not change layer if you try - you'd have to "unname" the ROD object before changing it. Cadence Online Support Solution 11157752 gives some tips on this.

Regards,

Andrew.

 Thank you again. It is working now :-)

I will take a look at the problem with the RODs now

Hello Andrew,

Sorry for bothering you again. But in case I want to make this script work through all the hierarchy what function do I need to use?

I tried with the leSearchHierarchy but it doesn´t work.

THank you very much,

Maria

Hello,

Does anyone know how to run the script through all the hierarchy?

I am still trying to find a solution for this. I tried different things but I didn't make it work.

Thank you,

Maria 

Hi Maria,

Something along these lines:

procedure(MYtraverseHier(cvId @optional (done makeTable('cellViewsDone nil)))
  ; do whatever change you want here - e.g. layer change
  ; now traverse the hierarchy
  foreach(master cvId~>instanceMasters
      ; filter out anything done before, or pcell instances
      ; could extend this condition to filter out certain libraries - do what you want
      unless(done[master] || master~>superMaster  
        done[master]=t
        MYtraverseHier(master done)
      )
  )
)

This is not tested, but it's a fairly standard recursive hierarchy traversal.

Regards,

Andrew

Thank you very much Andrew.

It works fine :-)
