Not able to copy MPP guardRing using dbCopyFig

San

Hi,

 I have single pcell instance , some pins, and a MPP guardRing around that instance in my layout view.
I just want top make a copy of all these an place it little farther.

I tried using following code. But it did not copy guardRing

layId = geGetEditCellView()

geSelectAll()

foreach(fig selectedSet()

dbCopyFig(fig layId list(10:0 "R0" 1))

)

Please help on this. I am not sure why it did not copy guardRing. Is it because it is ROD object ?

Thanks

Sanket

  • I searched (using the search icon in the top right hand corner of the Cadence main site - at the top of this page) for "dbCopyFig MPP" and found this (with my previous answer on this topic):

    Use dbMoveFig to move a MPP between different cellviews
    If a use dbMoveFig to move a MPP inside the same cellview, it works fine. If I use it to move the MPP to a different cellview however, only the main path is moved, and it is converted to a regular path…

  • Hi Andrew,

    Thanks for pointing me out to search icon. Before posting this, I also tried to search but cadence website might be going through some update it seems.  By the way thanks for the answer. I will have to figure out another way as it's not possible with skill.

  • Sanket,

    I think the interactive copy in the editor will do it. It's also possible to create an MPP in SKILL too (I have a solution Can I create a Multi Part Path in SKILL based on a technology file template? on this), so rather than copying, maybe you can reconstruct the MPP if you know the points from the master path and the template used to create it (unfortunately it's not so easy to determine which template was used to create an MPP).

    Regards,

    Andrew.

  • Hi Andrew, 

    Thanks for prompt response. Sure, creating MPP will work after fetching some information from the existing MPP I am trying to copy.

    But before I implement that, I am ready to use interactive skill if that is an easy way out (I am going to open my layout graphically for some callbacks anyways).  but I am not sure how to use leHiCopy() command. I tried to look for it in documentation and CDS.log file but could not determine how to use it.  Can you guide me on that please? I appreciate it.

  • Hi Sanket,

    Something like this:

    procedure(CCFcopyMPPbyDelta(mppMaster delta)
      geDeselectAllFig()
      geSelectFig(mppMaster)
      preXY(0:0)
      preXY(delta)
      leHiCopy()
    )

    Then if you have the master path for the MPP in a variable mpp you can do:
    CCFcopyMPPbyDelta(mpp 10:0)

    It leaves the resulting MPP selected; you could always add a geDeselectAllFig() at the end of the function above. The preXY calls are just a way of feeding in the clicks before you start an enter function. In this case, the first is the reference point, and the second is the destination - so the difference between them is the amount it gets shifted by in the copy.

    Of course, this only works with a graphical window open, since it's a "Hi" method of doing the copy.

    Regards,

    Andrew.

  • Thanks a lot Andrew. Your suggestion did the job precisely. I really appreciate your help.

    Thanks
    Sanket
