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

Hi,

    I have problem in controlling Hreadyin signal(to force it low randomly) from AHB eVC. Is there any existing sequence in versity's AHB eVC to create such scenario and also i am very thankful if anyone suggests me the other ways to control the Hreadyin signal.

Thanks in advance

Hello Srik,

the HREADY_IN is a result of the slave mux, the decoder and the HREADY_OUT signal of the responding slave. If this slave is controlled by an active agent from the eVC, you can control it's HREADY_OUT by using the delay field of the slave response or settings for reset. Have a look in the AHB eVC documentation (looking for HREADY and delay ).

Regards,

You can find the AHB eVC on the Cadence downloads site.
Please be aware though that it's a commercial product and needs a licence before you can run simulations.

Hi Guys,
Now i'm doing testcase for mux, dec and arbiter for 2 Master and 1 slave env buses.
I want to ask one question, let us say current transfer is M1 and the M2 requesting and also granted. but granted master getting address and data access control after some cycles or depends on previous master data control with hready. So is this is proper activity.

My slave does not support split transfer. is this related with retry transfer. can u give me details abt retry transfer.


Can you please reply me.
Thanks a lot.

Hi, I'm not sure if this will help, but, you can find information about how split transfers work in:
http://infocenter.arm.com/help/topic/com.arm.doc.ihi0011a/IHI0011.pdf
section 3.12

As to the scenario you described, I'm not sure I exactly understand what you have written. Since I'm not an AHB expert, I think I will let some of the other users answer that...

Cheers,
