finding single via

[prabhat.prem@gmail.com]

Hi
i am trying find single via in a layout through script or drc rule in
assura.
Please let me know if anyone having the same.
Also can this be converted to double via through skill without
creating DRC Error.
Thanks
Prabhat

Hi,
How far a via from another you consider that it is lonely ?

Hi Prabhat, Hi Sylvain,

To be entirely precise, lonely vias and single vias are not quite the
same thing.
From a manufacturing point of view (mainly Lithography, etching and
CMP) a lonely via might be double, triple or more as long as it does
not fulfill a certain density in a given area. Via density is critical
in nano processes.

Anyway, your question still makes sens, just wanted to highlight the
difference between a single via and a lonely via.
I'd rather go for a Assura/Calibre solution rather than a Skill
solution. In fact, MGC does provide tools for this kind of tasks, why
don't you use them ?

Cheers,
Riad.
