How to generate a list of display layers?

KokoLiu

Hi,

 I am using cadence virtuoso version IC6.1.5-64b.500.17. I would want to generate a list of layers that is already displaying in my Layout editor window.

 I already know there is a function call leLSWShowLayers(), but I am not using LSW. I am using layer palette. And I can't bring LSW up using leRaiseLSW() because my palette assistants are enabled.

 I can't use the solution in solution 20268008 by using pteRegisterUserSelectionTrigger because my cadence version isn't new enough.

 Please let me know what other ways I can produce a list of displayed layers?

 Thank you.

    Hi KoKo,

    You can get a list of the layers using SKILL, for example: 

    lcv = geGetEditCellView()
=> db:0x1a6dea12
lcv~>lpps~>layerName
=> ("Metal1" "Metal2" "edgeLayer")
hiGetCurrentWindow()->stopLevel = dbGetMaxHierDepth()-1 ;; I did Shift-F in the layout
lcv~>lpps~>layerName
=> ("Nwell" "Pimp" "WellBody" "Metal1" "Nimp"
     "allGeoShare" "Cont" "text" "Oxide" "Poly"
     "Metal2" "edgeLayer")
foreach(mapcar lpp lcv~>lpps list(lpp~>layerName lpp~>purpose))
=> (("Nwell" "drawing") ("Pimp" "drawing") 
       ("WellBody" "drawing") ("Metal1" "drawing") 
       ("Nimp" "drawing") ("allGeoShare" "GeoShare") 
       ("Cont" "drawing") ("text" "drawing") 
       ("Oxide" "drawing") ("Poly" "drawing")
       ("Metal2" "drawing") ("edgeLayer" "drawing"))

    Hopefully this is what you are looking for?

    Regards,

    Lawrence.

    Hi Lawrence,

     Thank you for your reply, but that wasn't what I am looking for. The skill code you provide will able to get a list of layers that are used in the cell. But I wish to get a list of layers that I set it as visible on the palette.

     Thanks,

    Koko

     Hi Koko,

    Try this instead:

    lays = leGetValidLayerList(techGetTechFile(geGetEditCellView()))
=> (("Oxide" "pin") 
     ("Metal1" "drawing") 
     ("Via1" "drawing") 
     ("Metal2" "drawing") 
     ("Via2" "drawing")
     ("Metal3" "drawing")
     ...
     ("designFlow" "drawing4") 
     ("designFlow" "drawing5")
     ("designFlow" "drawing6") 
     ("designFlow" "drawing7") 
     ("designFlow" "drawing8") 
     ("designFlow" "drawing9") 
     ("Row" "drawing")
 )

setof(lv lays leIsLayerVisible(lv))
=> (("Oxide" "pin") 
     ("Metal1" "drawing") 
     ("Via1" "drawing") 
     ("Metal2" "drawing") 
     ("Via2" "drawing")
     ("Metal3" "drawing") 
     ("Via3" "drawing") 
     ("Metal4" "drawing") 
     ("Via4" "drawing") 
     ("Metal5" "drawing")
     ("Via5" "drawing") 
     ("Metal6" "drawing") 
     ("Cont" "drawing")
     ("Cont" "pin") 
     ("Poly" "drawing")
     ("Nwell" "drawing") 
     ("Pwell" "drawing") 
     ("Oxide" "drawing") 
     ("Nburied" "drawing") 
     ("Nimp" "drawing")
     ("Pimp" "drawing") 
     ("Bondpad" "drawing") 
     ("text" "drawing")
 )

    This should be close enough to (if not exactly) what you are asking.

    Regards,

    Lawrence.
