How can I access/change stdVia enclosures in SKILL?

pilotrp

Hi,

I'm using Virtuoso version ICADV12.3-64b.500.9.  Currelntly, our defualt setup creates metal enclosures that are coincident with the cut shape boundary.  I'd like to modify the enclosures using SKILL to make them DRC clean.  Here's one example:

via~>viaHeader~>??
(db:0x3898833b cellView db:0x3898961a objType "stdViaHeader"
prop nil viaDef db:0x181f01ba viaDefName
"C9CKK1" master db:0x2071ec9a subHeaders nil
vias
(db:0x38987e27) overrideParams nil
)

I looked at the overrideParams in another via where I had manually edited the enclosures.  I saw this:

via2~>viaHeader~>??
(db:0x3898831b cellView db:0x3898961a objType "stdViaHeader"
prop nil viaDef db:0x181f01a7 viaDefName
"M0V0M1" master db:0x3a74ff1a subHeaders nil
vias
(db:0x38987e1c) overrideParams
(("layer1Enc"
(0.025 0.0)
)
("layer2Enc"
(0.008 0.025)
)))

I tried assigning the overrideParams to a similar list with different numerical values, but it errored out.  It also appears that the overrideParams property is nil unless you manually adjust the enclosures.

Can you tell me how I can adjust the via enclosures using SKILL for set of selected vias?

Thanks

    I dont have a list of all the variable for vias symbolics

    Some of the variables for stdVia and customVia are slightly different

    Example

    stdVia

    cutRows

    cutColums

    customVia

    cutRow

    cutColum

    Same variables

    cutWidth cutHeight cutSpacing

    If you can get your Cadence AE is give you an old SKILL small book.

    The book has all the functions in the finder gui. The book is kinda handy for something to thumb through
