stacked via location

You can use below SKILL code to get list of stacked vias and coordinates

;get all stacked vias in design
axlCmdRegister("get stackedvia" `getStackedVias)
(procedure getStackedVias()
(let (viaListAtLoc curViaNameList allVias curLoc viaList)

;get all Vias in design
viaLocMap=makeTable("ViaMapLocTable" nil)
axlSetFindFilter(?enabled list( "noall" "vias") ?onButtons list( "noall" "vias"))
axlAddSelectAll()
allVias = axlGetSelSet()

;Make a table for Via with location as key
(foreach curVia allVias
;printf("curVia is %s loc %L\n" curVia->name curVia->xy)
curLoc=curVia->xy
viaListAtLoc=viaLocMap[curLoc]
(if viaLocMap[curLoc] then
viaListAtLoc=cons(curVia viaListAtLoc )
viaLocMap[curLoc]=viaListAtLoc
else
viaLocMap[curLoc]=list(curVia)
)
)

;print List of Vias
printf("Stacked vias \n")
(foreach key viaLocMap
viaList=viaLocMap[key]
curViaNameList=list()
(if length(viaList) > 1 then
(foreach curVia viaList
curViaNameList = cons( curVia->name curViaNameList)
;printf("\tvia %s \n" curVia->name )
)
printf("%L : %L\n" key curViaNameList)

)
);
(axlShell "done")
);let
);procedure

if you want to visually see them on the board, turn on "Drill Labels" in the design parameters.

thank u for your response.

my design has over 1 million vias so i can not visually check drill labels one by one unfortunately.

Hi masamasa!

You can refer my code. My design has over 150 thousand vias. i apply rule via same location only, no same pad.
