How should we found a multipart path instance in a cell view.

VEERA PRAMOD

Hi all..

I had drawn some multipartpaths in a cell view.How should i know it is multipartpath instance or not using CIW.If any one knows please give me the solution. 

 

Thank you.

  • Veera,

    I'm not entirely sure I understand your question. I'm assuming you're asking if you can tell the difference between a multipart path created via the Create->Multipart Path menu (perhaps using a template) and one created using SKILL?

    If so, the answer is "no". There is no information on the MPP ROD object (or the db object for the master path) which records whoich template was used to create it, let alone the method of creation.

    Why do you need to know?

    Regards,

  • Hi Veera,

    If you want to find which of all the paths are multi-part paths as opposed to regular paths, then you can first check the ROD-iness of the path and then check for sub-parts, this will identify it as a multipart path. For example:

    ;; find the rod shapes, not specifically paths
     setof(sh cv~>shapes rodGetObj(sh))
    => (db:0x4532da92 db:0x4532da94)
    ;; find and select all rod path objects
     mapc('geSelectFig setof(sh cv~>shapes sh~>objType=="path" && rodGetObj(sh)))
    => (db:0x4532da92 db:0x4532da94)
    ;; iterate over all shapes and find only rod paths that have sub-parts
     foreach(sh cv~>shapes
     when(sh~>objType=="path" && rod=rodGetObj(sh)
       when(rod~>subShapes
        geSelectFig(sh))
      )
    )

     I hope that this is what you were looking for.

  • Veera,

    See - Lawrence and I had two completely different interpretations of your question. Just shows the importance of asking a complete and precise question!

  • Hi,

      I am facing a similar issue. I am using "dbCopyFig" on a multipart path but it doesnt copy the subparts. It just copies the base path.

    I tried to see if there is any MPP property for the obj by dbId~>? and Im not able to find any.

    So How do I make dbCopyFig work for MPP.

     

    Thanks,

  • You can use rodGetObj on a shape to see if it is a rod object (a multi-part path is a ROD object - Relative Object Design). You can also use rodGetNamedShapes on a cellview id to get all of the rodObjects in the cellview. From the rod object id, you can get the shape ids of all the sub-parts of that multi-part path. In this way you can treat these MPP shapes different from other shapes in your cell. However, as far as I know, there is not currently a way to copy the multi-part path in Skill code. You can copy it interactively using leHiCopy, but I don't think you can do it in a script. Maybe someone from Cadence can confirm this.

    Here is how you would get the shape ids that are in your MPPs in your cellView:
    cv = geGetEditCellView()
    rodParts = nil
    foreach(shp cv~>shapes
        when(r=rodGetObj(shp)
            foreach(subShp r~>subShapes
                rodParts = cons(subShp rodParts)
            )
        )
    )

  • Derek's right. In fact there's a "non solution" solution 11011335 which describes this limitation.
