How to change contact overrideParams?(ver. 6.1.6)

We use new via instance from virtuoso IC ver.6. I want to change the number of row or column of via instances by SKILL. When we select a via and click 'q', we see 'Edit Via Properties' window. and then we can change the num of row or column of via by entering a new wanting value. I found the property is viaHeader~>overrideParams and the data structure is a list. So I tried to alter the list to a new changed list and saw this error message like this. *Error* setSGq :(DB-370034): dqSetq: Cannot set attribute - overrideParams How can I solve this problem? Is there any other possibility to do this?

Hi,

I think it works with "dbReplaceProp" .

Adrian is right - you can also use via~>cutRows=N (i.e. directly set the properties on the via itself) - it will automatically sort out the viaHeader updates for you if you do this. You can also use dbReplacePropList.

Regards,

Andrew
