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.

Best regards,
Mike and Tom

Hi
I am trying to find good way how to check the distance between two different class/subclass.
Expecially soldermask and goldmask distance of film artwork is major concern because the minimun distance is required by 0.3mm so manual check is very tedious for small pcb design.

Please address how to make skill program for this distance check.

Thanks in advance

Hi BK,

You may be able to use the axlAirGap command.
axlAirGap(obj1 obj2)
This will work for shapes on different classes.

Thanks Dave

I tried to run like this as axlAirGap(Solder_mask Gold_mask ), but return fail.
I am not Skill expert, so please write some code more detailly.

Hmmm, you really are jumping in at the deep end!
First you need to get the dbid of each of the objects that you want to measure between.
Typically you might want to find the minimum distance between all shapes on a single subclass.

shapes = axlDBGetShapes("manufacturing/solder_mask")
minGap = nil
while(cdr(shapes)
shp1 = car(shapes), shps = cdr(shapes)
foreach(shp2, shps
gap = caddr(axlAirGap(shp1, shp2))
minGap = if(minGap then min(minGap, gap) else gap)
)
)
minGap; Rturn the minimum gap between shapes on this subclass.

This code will be slightly more complex if you are measuring between two subclasses - but you should be able to figure it out.
