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

    Andy,

    If your via spacing is dependent upon the number of vias, that can be encoded as a technology rule in the constraints in the tech file. Isn't that a better solution than having to compute it yourself every time you change the number of rows and columns? That way it will be correct no matter how you enter the rows and columns of the via...

    Look for viaSpacing in cdnshelp and you should find it descrbed in the Virtuoso Technology Data ASCII Files Reference manual.

    Andrew.
