cutClass of vias through skill code

You can change the cut with

viaDB~>cutWidth and

viaDB~>cutHeight

Here are some older post that may help on getting techfile via cut dimensions

i am using dbCreateVia function, and i am giving parameters like this:

viaparams=list(list("cutRows" height) list("cutColumns" 1) list("cutWidth" .064) list("cutHeight" .032))...................................(1)

In the documentation of dbCreateVia, i read that there is a parameter which we can pass as "cutSpacing".

I am trying to give y spacing from via to via as .096um but if i add parameter "cutSpacing" the code of via doesnot run. 

code (1) runs smoothly, but if i add "cutSpacing" sublist too, then the code doesnt work. 

How to give via to via spacing in y direction using dbCreateVia function? 

Thanks!

It does tend to help if you actually show what you've tried, as then it would be much simpler to see what you'd done wrong.

The cutSpacing needs to be a list of two values - the x and y spacing:

viaparams=list(list("cutRows" height) list("cutColumns" 1) list("cutWidth" .064) list("cutHeight" .032) list("cutSpacing" list(0.096 0.096)))

Here I just specified both the x and y spacing as 0.096 - but you can of adjust as you need.

Thank you Andrew! i was not giving list(x y). Now it works! 

As a suggestion to cadence documentation team, they should add an example for each parameter so that people like me who are new to SKILL can use the function without problems. 

Thanks once again!

BTW, I did file CCR 1898684 with some suggestions on how to improve the documentation for dbCreateVia - I agree, it's a bit lacking in detail.
