SKILL for changing via.

I want to write a skill code for changing vias. For eg:
I will make 2 bindkeys, one for changing via to up metal level and other for changing via to down metal level.

Below i am planning to change via M1V1M2 to via M2V2M3.

What am i planning to do is to select a via, and querying it to get its via definition name as shown below:

geGetSelSet()~>viaHeader~>viaDefName ........(1) =>("M1V1M2")

Now i planned to change this list(destructively) to the via definition since i want to change the via one metal level up:

setcar(geGetSelSet()~>viaHeader~>viaDefName "M2V2M3") ............(2) =>("M2V2M3")

But nothing happens. After running code(2), when i again run code(1), it gives me code(1)'s output i.e ("M1V1M2").

I am doing wrong. Can you help?!

Thanks!

As I explained above, you have to either use leReplace, or delete and re-add the via (dbDeleteObject() and then dbCreateVia()).

Regards,

Andrew.

I used leReplace but while doing that it will take lot of time to change the via any solution for that?

That's not very specific - you've not given any clue as to what exactly the problem is - how much is a lot of time? What precisely are you doing? Which version are you using? This really should be a new thread - see Guidelines for the Custom IC SKILL Forum

That doesn't give anywhere enough information. "A version of 6.1" could mean one of IC6.1.0, IC6.1.1, IC6.1.2, IC6.1.3, IC6.1.4, IC6.1.5, IC6.1.6, IC6.1.7, IC6.1.8 - that's nine major releases over 13 years. You didn't give any indication on how you were calling leReplace - what are the arguments?

I suggest you contact customer support, so that at least an application engineer could have a web session with you to look at your data.

Regards,

Andrew
