Hi Frank, The feature of updating abutted or overlapping shapes is an interactive Layout XL feature, and thus it does not occur for non-interactive SKILL code. I believe that this is part of the...

Thanks Lawrence, I agree with you that I can check for overlaps, and change the connectivity, yes this could be a work around, but I don't have a work around for pcell parameters. That is, if I change...

Priyankar, Which IC version are you using? Type getVersion(t) in the CIW... The create via form changes quite a bit from one version to another, so it's important to know. I didn't see an option to...

Andrew, Thanks for your prompt reply. It is good to know that this warning is harmless. I will follow the given work around. Thanks Syafiq

OK, you were talking about saving via variants, not custom vias. I wondered whether that was what you meant, but given you were talking about "icfb" (which the tool has not been called since IC611 or...

Andrew, I understand this approach, but as soon as i restart my icfb my save vias are lost, how can i keep them intact for later use ? regards, Priyankar

Hi Andrew, Thanks That is right it was my mistake i didnt notice that. But when i try to access the same via in different design i am not able to access how can i do that ? Regards, Priyankar

Hi Priyanka, When you save a viaVariant into a design, it's only for that design. You'd have to save it to the technology library if you want to share it amongst multiple designs (you could always...
