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 have been running HSPICE simulations from SigXP for a while - works very well with the Xilinx design kit for RocketIO.

For those unfamiliar with this, SigXP targets HSPICE instead of TLSim and the DML models are wrapped HSPICE. The results are displayed back in SigWave.

I need to do the same with some customer supplied HSPICE IO models. However, these models require the foundry libraries (e.g. TSMC 0.15um library). I have been told that I would have to buy these libraries to simulate the supplied encryted HSPICE. Is this true?!!! That means that if a customer can't supply the libraries then to run their simulation I would have to buy the same foundry models that they already own. Can this be true? How do people normally run simulations of people's HSPICE? Are the relavent libraries normally supplied?

Does anyone have any experience of this?

Hi,

My problem is little differ!!
I am spectarquest 15.2 user.

I have Hspice model (I don't know which format) of usb switch.

You can download the models from http://www.fairchildsemi.com/pf/FS/FSUSB22.html#models (I can not attach due to some end user licence issue)..

My question is can I use this model in spectraquest instead of IBIS?

Please reply ASAP........ (Are you listning cadence?)

Waiting for reply.

For Chris' question:
Whatever the libs you need to run HSpice, Allegro PCB SI will need them to run simulations. The reason is that we will run HSpice as the simulator in aSI environment.

For Naren's question:
Yes, you can use HSpice model in Sigxp instead of IBIS. But you need to have proper HSpice simulator and license to run.

Hope this helps.
