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 am working with my company to figure out the best way for our manufacturing and remote service centers to use the schematic/pcb tools. We recently changed from PCAD to allegro hdl. PCAD offered a free schematic viewer and a free pcb viewer that allowed "cross probing." This meant that when a tech troubleshot a board, they could highlight a net in either the schematic or on the layout and see where it went in the design. The allegro tools at this time have no such functionality. They provide a free physical viewer, but not a logical one.

How have you worked around issues like this?

According to sourcelink, cadence has a free viewer in the roadmap, but with no definite date.

Maybe if we all bond together and yell loud enough, they will add it to the 16.0 release!

Thanks in advance.

Matt

Hi Matt,

The Allegro PDF Publisher might be what you want although it's not free to publish your schematics in intellegent PDF.
I saw a demo at CDNLive earlier this month and the pdf files produced are every bit as useful as any free viewer.
I think it's overpriced at the rumoured list price.
It's available in 15.7

Cheers, Dave

I have looked at that. Pretty useful tool, and I agree, WAY overpriced. But hey, its Cadence ;-)

The functionality that would be missing would be the ability to cross probe. Select or highight a net in the schematic and the same net is highlighed in the layout.

Agreed. The PDF Design Publisher is a worthy upgrade but, as Matt said, it is severely overpriced It is NO substitute for a viewer as it is missing the critical feature that a viewer should have - cross-probing.

Many [most, in fact] other major EDA vendors have functionally complete but feature-reduced viewers: Protel, P-CAD, Altium, PADS, and CADSTAR. Not having a cross-probing viewer for EITHER the Concept/Allegro or Capture/Layout Plus suites is an amazing omission from a company that should be leading the way in EDA. It makes the availability of the Allegro Physical Viewer essentially worthless to my company. I can think of lots of uses for a viewer, and as there's an Allegro Physical Viewer from Cadence and viewers from the companies/packages listed above, there is an obvious need for a viewer by Cadence's customers.

Maybe sometime, delayed by many years, and for an outrageous amount of money we can see a Concept viewer from Cadence. I'm not holding my breath, but hey, Vista is only days away from being released so anything is possible.

C'mon Cadence: it's now 2007 - GET WITH THE PROGRAM!!
