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 was trying to run a typical pss/qpss simulation of a mixer circuit. The simulation always crashes, saying insufficient memory. I checked the system resource, and was sure that system resource (including memory) was littlely used. Did anyone has similar situation and any tips to solve the problem? Otherwise I have to run transient simulation and do dft to check the result which is very painful. I am using icfb 5.10.41_USR3.27.

Thanks in adance.

Without getting into the details of your RF simulation, try reducing your data points, using the swapfile option, using the new parser (+csfe), and finally, 64bit Spectre.

I strongly suggest using a newer version of Spectre (the USR3 version you are using dates back 2005). There have since been memory handling improvements in Spectre. Try using IC5141USR5 or better MMSIM6.2.

A thorough list of suggestions is available here:

So far, swap-file and save-selected, both in the output option and simulator option, help quite a bit. Though sometimes still get that crash issue.
