newbie to skill scripting

Sorry for the confusion,

stretching/chopping of of vias is a 616 feature (as Andrew says,  it's not, by default, enabled at the moment). Contact Cadence if you want to evaluate this.

Stretching (but NOT chopping) of mosaics is also a  6.1.6 feature and is not an early adopter feature so you should be able to use it

Mosaics cannot be chopped

Hi! I am using 6.1.7. Do stretching via instance is already enabled in 6.1.7 or 6.1.8 versions by default ? As, this help in extending via in one direction without effecting the other side edge coordinates. I tried various attempt but couldn't succeed to do so. If it is already enabled can someone, tell me the steps to do it. Or can share where in the virtuoso pdf / video if this is mentioned ?

Another, thing I notice: I have been seeing this since 6.1.6 or 6.1.7 version that a - Via Preview Bindkeys ( dialogue window) appears when we use auto via with some default bind key display to use, but never ever found it working. Further any idea of "Fast-edit" via option work (mentioned in via property form)?

Appreciate your help. Thanks.

Yes, it's a standard feature from IC617 onwards. I just checked in the base release of IC617 (as well as the latest IC618 hot fix) and in both you need to first go to Options->Selection and turn on Via Partial Selection:

You'll then find during the stretch command you can partially select the edges of vias and stretch them. If you hit the "F3" key during the stretch command you'll see this popup:

The Via Mode in the Special Objects section allows control about precisely how it does the stretch. Stretch Metal means that the metal area is stretched and the rows/columns are recomputed (i.e the metal overlaps may vary). With Row/Col mode the metal overlaps remain the same, and only the rows and columns are stretched in discrete chunks.

I couldn't find a video on this, but it's pretty straightforward - the key is enabling partial selection of vias first.

Regards,

Andrew.
