How to determine if SILKSCREEN_TOP REFDES is visible

redwire

Hi

I'm working my way thru SKILL and can find all my components.  I then look at the component symbol to find its children from which I find SILKSCREEN_TOP

However, I don't know how to determine if it's visible or not.  This is a result from a command line query on the dbid which I have assigned to "cmpChild":

cmpChild->??

(prop nil bBox

((5.8492 16.1326)

(6.5508 17.3008)

) readOnly

t objType "text" layer "PACKAGE GEOMETRY/SILKSCREEN_TOP"

xy

(5.9 16.45) text "2" textBlock

"2" rotation 0.0 parent dbid:00000000429AF9F8

mirrorType "NO" isMirrored nil justify

"LEFT" parentGroups nil

)

Is there an easy way to determine if I have deleted the ref des or not?  In this case, I have deleted it but I can't find the property which tells me it's been deleted.

Thanks
Bill

  • hopefully the code below will help you figure this issue out, I wrote this to flag components with missing refdes silkcreen text ( cap, res & ferrite beads are excluded )

    procedure((check_missing_silk)
    let(( layerName errcnt RefList dbid Class ) 
    (errcnt = 0)
    (layerName = "REF DES/SILKSCREEN_")
    (RefList = setof(sym, axlDBGetDesign()->symbols, sym->refdes && !exists(obj, sym->children, obj->text == sym->refdes && index(obj->layer, layerName)))~>refdes)
    foreach(ref RefList
    rexCompile("^[CR][0-9]")
    unless( rexExecute(ref)
    unless(rexMatchp("^FB[0-9]" ref)
    (axlClearSelSet)
    (axlSetFindFilter ?enabled list("noall" "symbols" "invisible") ?onButtons list("noall" "symbols"))
    (dbid = car(axlGetSelSet(axlAddSelectName("SYMBOL" ref))))
    when(dbid
    if(dbid->isMirrored then
    (Class = "DRC ERROR CLASS/PACKAGE_BOTTOM")
    else
    (Class = "DRC ERROR CLASS/PACKAGE_TOP")
    )
    (dbid = axlDBCreateExternalDRC("missing silkscreen refdes" (dbid->xy) Class list(dbid) nil nil))
    when(dbid
    (errcnt++)
    )
    )
    )
    )
    )
    axlMsgPut("%d violations found" errcnt)
    )
    )
