Create a Via with the same parameters as what "auto" option provided on the "Create Via Form"

 Hi there,

I am very new to this community. I am trying to implement creating via automatically using skill code. Thanks for all the information that you provided. I was able to place the via wher I want using skill code. However, in terms of the VIA params, I would like to create a via with the same parameters as what "auto" option provided on the "Via form". The auto via will cover all overlap area and extend over a little bit. Also, it won't violate the DRC rule, etc. I tried to use lxComputeViaParams for the viaDef that from tech file, but it didn't give much info. Is there any SKILL function to do that? 

Thanks,

Yanhong

            tf=techGetTechFile(cv)
            viaDef=techFindViaDefByName(tf viaDefName)
            via_center_point_x=(car(viabox_ll)+car(viabox_ur))/2
            via_center_point_y=(cadr(viabox_ll)+cadr(viabox_ur))/2
            via_center_point=list(via_center_point_x via_center_point_y)

            viaParams=list(list("cutRows" evalstring(cutRows)) list("cutColumns"     evalstring(cutColumns)) )

            ;viaParams=append(viaParams lxComputeViaParams(viaId cv viaParams))
            existing_via=setof(z dbGetTrueOverlaps(cv list(viabox_ll viabox_ur)) rexMatchp("Via" z~>objType)==t)
            if(existing_via
              then
              printf("There is an existing VIA. No Via will be created.\n")
            else
              if(viaDef
                via0=dbCreateVia(cv viaDef via_center_point "R90" viaParams)
