Many of you already received communications about the move of the Cadence user community into cadence.com. And many of you have already joined, with over 4000 registrations in the first two weeks.

The new Cadence Community enhances the ability of Cadence users to connect and collaborate. In addition to moving the community into cadence.com -- enabling single sign-on for community, Sourcelink and Cadence events -- the new site is organized around nine technology segments, giving you easy access to product information, training, forums and blogs. Some of the new features include:
  • Ability to respond to posts via e-mail
  • Technology-specific blogs
  • Latest Web 2.0 social networking capabilities
  • Public profile options
  • Private messaging
  • Friends lists
Visit the new Cadence Community today at www.cadence.com/community and join the discussions!

Registration note: Due to the scope of the enhancements and the new SSO registration system, we were not able to migrate existing cdnusers.org member accounts. So new registrations are required, but this enables a broader set of functionality we think you'll enjoy.

Forum note: Under the guidance of forum moderators, we have taken the 20+ cdnusers.org forums and consolidated them into 11 forums on the new site. Posts have been brought over so you can leverage that posting history. CDNusers forums will be set to read only starting 7/30, and cdnusers.org will be redirected to the new community on 8/4.

Mike and Tom

Hi Stella,

Nice to hear from you.

This is not a difficult task - try using the axlPolyFromDB command.

eg. poly = car(axlPolyFromDB(via_dbid ?layer "ETCH/TOP" ?padType "REGULAR"))

You can then create a keepout shape on the appropriate layer using axlDBCreateShape:

axlDBCreateShape(poly, t, layer)

I hope this helps.

Cheers, Dave

Hi Dave,

Nice to hear from you and glad that you are moderating this forum.  Guess I have a lot to learn from you.

I left out a some detail.  I am looking for slightly more ie the wire keepout to be created will exclude any cline connect to the via.    In the attached.  Thanks for the code, it is a good starting point.


Regards,
Stella

Hi Stella,

Have a look at the attached code. I hope it helps.
It makes use of the axlPoly commands which are great for doing this type of task.

Cheers, Dave

Hi Dave,

Thanks for the great help.  I did a little customisation and now I am using it for my design. 

Have a nice weekend.

Dave,

Stella is working at the board level, in particular, the vias on the board level.

Can you give me your reasoning for putting the new "WIRE_KEEPOUT" subclass within the "PACKAGE GEOMETRY" class?

thanks,
jcr

Hi J.C.

It's just example code. I don't know what Stella's "wire keepout" layer is. Yes, it should probably be a BOARD GEOMETRY feature. I assumed that anyone using the code would modify it for their own purposes. Hence the function name "stella"

Cheers, Dave
