update "cutSpacing" of a via

chianga

Hi guys,

Long time lurker, first time poster.  I first want to thank Andrew, Lawrence and other regulars for contributing to this forum.

 I have a simple problem that I can't seem to figure out and I am hoping you guys can point me to the right direction.  I am trying to update the "cutSpacing" of a via using the following code, where cutSpacing= x_width:y_width and I got the error below

*Error* dbReplacePropList: Invalid float - (0.09 0.09)

I figured I am not setting the type of "cutSpacing" correctly but I can't figure what it should be. 

  dbReplacePropList(fig

               list(

   list("cutSpacing" 'float cutSpacing)

                   list("cutColumns" 'int numCols)

                   list("cutRows" 'int numRows)

   )

) 

Thanks in advance,

Andy

PS I am using IC6.1.5-64b.500.12

     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)
