axlBackDrill function

czilka

Hi SKILL community,

I’m using axlBackDrill function.

axlBackDrill(o_dbid s_layer) -> l_result/nil

 

Allegro SKILL Reference has an example

result = axlBackDrill(pin, 'bottom)

 

I would like instead of using specific layer ('bottom or 'top) get the layer specified in “Backdrill Setup and Analysis”

 

Does anyone knows how to get s_layer from the design?

 

Thanks,

  • Hi Carmen,

    Hopefully this function will help you:

    defun( DE_getBackDrillLayers ()
    let((paramFileName, p, ln, layerNum, fromLayer, bkdrillLayers)
    paramFileName = strcat(axlCurrentDesign(), "commandParams.prm")
    axlExportXmlDBRecords(paramFileName, '("Application or Command Parameters"))
    p = axlDMOpenFile("ALLEGRO_PARAMETER_FILE", paramFileName, "r")
    while(p && gets(ln, p) && !bkdrillLayers
    when(index(ln, "<backdrill_parm_type>")
    layerNum = fromLayer = nil
    while(gets(ln, p) && !index(ln, "</backdrill_parm_type>")
    when(index(ln, "<layerNum>"), layerNum = cadr(parseString(ln, " <>\n")))
    when(index(ln, "<fromLayer>"), fromLayer = cadr(parseString(ln, " <>\n")))
    )
    when(layerNum && fromLayer, bkdrillLayers = list(fromLayer, layerNum))
    ); when
    ); while
    axlDMClose(p)
    bkdrillLayers
    ))
