geomSize( Layer -ve downUp) why -ve value?

[Reotaro Hashemoto]

Hi,

If I'm using geomSize(lay1 -1 downUp) for example, does that mean I
will be sizing lay1 by 1 down (or roughly sizing it by -1) then size
it by 1?

I'm confused with the negative sign.. Can anyone explain it?

Thanks and regards,
Ahmad

Salam Ahmad,

I saw you have posted few questions about Assura these days. I would
have loved to help your but I was busy the past couple of weeks and
I'm doing my hardest to catch up really ...
I have been through your questions and many of them are just well
explained in the Assura documentation. It's really worth looking at
the doc.
The doc is available from the $ASSURAHOME/doc. You could use the
cdnshelp.
There are the docs that might help you:

1. Assura Physical Verification Command Reference
$ASSURAHOME/doc/assuracommandref/assuracommandref.pdf
that's what you need to find information about all the functions you
are asking for: geomSize ... etc. It is a KOF dictionary really.

2. Assura Physical Verification Developer Guide
$ASSURAHOME/doc/assuradev/assuradev.pdf
That's a primer for the deck developers like you

3. CadenceAssura Physical Verification User Guide
$ASSURAHOME/doc/assurauser/assurauser.pdf
That's what everybody uses to know how to set the DRC/LVS/RCX runs ...
etc.

So if you still find problems after this, then you are more than
welcome to back again.
Please take my comments as advice not as instructions I'm learning
a lot from the docs and just wanted to share this experience.

Looking forward to e-talk to you soon

Regards,
Riad.
