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

I am running LVS on a large pixel array (16-mega pixel) which contains nothing but repeating the unit pixel. The pixel array is organized in a hierarchal systems consisting of cells that group increasing number of pixels (ie 1-pixel cell, 10-pixel cell made of 10 of 1-pixel cells, 100-pixel cell made of 10 of 10-pixel cells, 1000-pixel cell made of 10 of 100-pixel cells, and so on). Both the schematic and the layout have the same structure and pins. My problem now is that when I run LVS it eats up all the memory available on the system (4 GB, the maximum memory a 32-bit system can have) and LVS stops. I thought by structuring my design in a hierarchal way the runtime and memory requirements would be minimized. Am I doing something wrong so LVS would need > 4 GB of memory? Or this is the case for everyone who need to check large array designs (such as cameral pixel arrays or memory arrays)?

It might help if you said which LVS tool you're using... since Cadence have four, it's a little hard to tell what you're doing.
