get via coloring

psill000

Is there another method of getting and setting the via coloring?

I had a used a script to get and set via coloring but it doesnt seem to work now.

The via is a stdVia with mask2Color locked on layer2 as indicated from the property gui

I have tried

dbGetViaLayerControl

dbGetViaCutLayerControl

dbGetViaLayer1Control

dbGetViaLayer2Control

dbIsViaColorStateLayerLocked

dbGetViaLayerNumColorMasks

All return noColor, noShift or nil

  • Paul, 

    Should be sth similar to this code:

    layer1Num = via_Id->viaHeader->viaDef->layer1Num

    layer2Num = via_Id->viaHeader->viaDef->layer2Num

    cv_id = dbOpenCellViewByType( "wo_kourany" "test" "layout" "maskLayout" "r" )

    drGetPacket("display" techGetLPPacketName(car(nth(layerNum1 techGetTechFile(cv_id)->layers)->lps)))

    Output should like this:


    ("display" "Metal4Bnd" "blank" "solid" "yellow"
        "yellow" "outline"
    )

    Regards, 

    Taher.

    Taher - wrong kind of color. You're talking about the display color, whereas this is about Advanced node coloring (which is related to multiple patterning of the masks - each metal1 mask is assigned a color name to distinguish it).

    Paul - to get whether the via mask is locked, you'd use dbIsViaColorStateLayerLocked(viaId "cutLayer") ; or "layer1" or "layer2". There is also the function dbSetViaColorStateLayerLocked to set the lock status of each layer. There's also dbSetViaColorInfo which allows you to set the color and the lock status of each layer (and in fact do all of them in one shot) - this function was added in ICADV122 ISR6 (so also in ICADV123 ISR7 which was the subsequent ISR). The dbGetViaLayerControl/dbSetViaLayerControl and the individual db{Get,Set}Via{Layer1,Layer2,CutLayer}Control functions also work too (although you need to make sure they are unlocked before changing them). The control is described as a shift (so noColor==grey, noShift==mask1Color, shift1=mask2Color).

    Unfortunately there's no nice dbGetViaColorInfo which I think would make life a bit simpler...

    I would say that the documentation for dbSetViaColorInfo shows setting them together, and then retrieving them with the individual APIs.

    Andrew, 

    Thanks for clarification, wasn't very clear from the description.
