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,

Id like to attempt a skill program that takes the ref des. in Allegro and auto matically rotates them either 0 or 90 degrees. I dont have any experience with SKILL but I was looking thru the functions and did not see anything that would help. What is the best way to get started? I looked at the Cadence samples but these are all mathematical computation type of routines. Where would I find a routine that manipulates an Allegro database?

Thanks,

mw

All,
Moody's paper is also published on this community site under PCB Design/Technical Resources/SKILL. URL is http://www.cadence.com/community/allegro/Resources/resources_PCB/skill/tpamkor_skillcustomization.pdf

This is quite tricky.
You have to select all text on the appropriate layes, i.e:

axlClearSelSet()
axlSetFindFilter( ?enabled (list "noall" "invisible" "text") ?onButtons (list "text"))
text_list = axlGetSelSet( axlAddSelectAll())
axlCloseFindFilter()

this gives all kind of text in the list text_list.
Now iterate (use foreach) every element and check if it's on the appropriate layer i.e.:

foreach( text_db text_list
cond(
(text_db->layer == "REF DES/ASSEMBLY_TOP"
do_something( text_db)
)
);end-cond
);end-foreach

in do_something() you have to remenber the parent id, the old text and then you delete te old text and create a new one with the right parent..

axlDBCreateText(
old_dbid->text
old_dbid->xy
new_orientation
old_dbid->layer
old_dbid->parent)

axlDeleteObject( old_dbid)

That's it.
