leCreateContact in IC6

 Hi Ghosh,

In IC61x the underlying database is OpenAccess (as opposed to "CDB" for IC5141 and earlier), and as such vias (and "contacts") are no longer instances, but instead they are objects.  The underlying data base change no doubt required changes in the API. There is a function "leHiCreateVia" but this is not a direct replacement of the leCreateContact function.  There are also "dbCreateVia" and "dbCreateViaShapeArray" which might be useful to you.  You would first need to find the "via definition", so you might need something like "techFindViaDefByName", "techFindViaVariantByName", "techFindViaVariant", "dbFindViaHeaderByName" or "dbFindViaVariantByName" - I'm not sure which you would need as I've not played with creating a via placement through SKILL rather than through the interactive GUI commands.

I hope that this helps you.

Lawrence.

Thanks Lawrence,

dbCreatevia is working fine.

 Hi Lawrence,

I used  "techFindViaDefByName" and  "dbCreateVia"  to create via array in my layout, through skill. I am specifying the "cutRows" and "cutColumns" in l_params list. It is working fine.  But I am not able to find the keywords to specify the Row spacing and Column spacing, without which it is placing with default tech-defined spacing(or minimum spacing). Is there any ?

 Regards

Ghosh

Ghosh,

It's cutSpacing which is a list - the first entry is the column spacing, and the second is the row spacing.
