Changing from one metal layer to another metal layer

Is this something you wish to do repeatedly or just a one-off? If it's a one-off I'd just use the ui.

I would like to change the metal layers inside the PR boundary only. Like outside the PR boundary I dont want to change the layer 

That doesn't answer the question.

N.B Area select entirely feasible.

This thread from a previous question goes part of the way...

Skill code to copy object to another metal layer but maintain the objects purpose - Custom IC SKILL - Cadence Technology Forums - Cadence Community

I would like to do it repeatedly and moreover one thing we can do change change metal layer "X" to metal "Y" within a specific area (coordinate location)

Hi,

You could use ABE (Advance Boolean Engine) but this will require your layout to be flattened

1. Extract the metal, using:

abeInit, abeLayerFromCellView

2. Create a boolean layer for the prBoundary, using:

abeNewLayer, abeLayerOrPtArray 

3. Make the AND operation between boundary and metal:

abeNewLayer, abeLayerAnd

4. Generate the new metal :

abeLayerToCellView

5. Chop remaining metal shapes

Use abeIslandIterator, Flatten the layout inside, then delete shapes using the island points and leChopShape

6. Close ABE

abeDone

Thanks for the explanation ,

Can you please provide a code for that 

Sorry, but this is not a forum for custom SKILL deliveries...

Try to do it by yourself and if you have questions about your code, I'll be happy to answer them

I am able to do it now and one last doubt ,if I want to change a particular metal layer from one to another outside the PR boundary then how can I proceed?

Basically I am facing issues in deleting a particular metal layer outside PR Boundary.

I shall be grateful to you if you kindly help me regarding this

Hi,

This is almost the same thing as inside

The trick is to work with an ABE layer that is defined using prboundary and cellview bbox

(let ((abe_cv               (abeNewLayer))
      (abe_inside_boundary  (abeNewLayer))
      (abe_outside_boundary (abeNewLayer))
      )
  ;; Define cellview bounding box layer
  (destructuringBind ((x0 y0) (x1 y1)) (geGetEditCellView)->bBox
    (abeLayerOrPtArray (list x0:y0 x1:y0 x1:y1 x0:y1) abe_cv)
    )
  ;; Define prBoundary layer
  (abeLayerOrPtArray (geGetEditCellView)->prBoundary->points abe_inside_boundary)
  ;; Define not prBoundary layer
  (abeLayerAndNot abe_cv abe_inside_boundary abe_outside_boundary)
  abe_outside_boundary
  )
