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

Hello all,
I have Allegro V. 15.1 and just downloaded ODB++ inside from Valor.
Never used it before. Is it worth using. I know quite a few people use it these days.
What advantages does it give over RS-274X?
Just starting to look around in the Valor Universal Free Viewer.

Any input or helpful hints would be appreciated.

Thanks,
Mark

Basically, the ODB++ Inside gives you the ability to generate manufacturing files which can be used by many fabricators today to fabricate PCBs. ODB++ is an all-in-one manufacturing output which also includes component placement information that can be used to drive placement machines during Assembly.

I would ask the fabrication houses your company deals with to see what they prefer but if they are using Valor today to CAM up the data then most likely they would prefer the ODB++ Format over RS-274X.

We have Valor Enterprise internally to run a series of DFM checks prior to releasing for fabrication so I have never used/setup the Valor Universal Free Viewer. I did play with it originally and it appears to be a scaled down version of Valor Enterprise to simply view the output from Allegro.

Hi Mark,
We now supply ODB++ to most of our suppliers. Those that didn't have ODB++ importing capabilities were happy to add it to their tools. I believe that it's already included with some tools and about $500 for others (such as GCCAM).
One of the main advantages is being able to supply intelligent data. This assists the fabricator to understand the design and communicate more clearly with you. I.e you can discuss the annular ring on pin 23 carring signal CLK on IC1.
Cadence's Gerber format is not the most popular so ODB++ does make your supplier happier.
We manipulate ODB++ for array design (far easier than other methods) - but that's another story...
Cheers, Dave
