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

  • 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.

Hi All,

I am using simvision version6.2 .
I need to see fields in simvision's waveform browser in my environment.
For that I need to creat probs (this is written in cdns help).

In this journy I tried to creat some probs by following command but it gives error.

Command : probe -create xbus_tb_top.xbus_demo_base_test.xbus_demo_tb0.scoreboard0.num_writes -tasks -functions -database waves -waveform

Error :  ncsim: *E,PEXCHR: Extra characters after object name: '.xbus_demo_tb0.scoreboard0.num_writes'.

So any one help me regarding same.

Ultimetly I need to see waveform of fields of SV classes .

Thanks in advance;
Gaurav

You can use transaction recording to display data items in the waveform. Look at the xbus_monitor.sv file and search for begin_tr() and end_tr(). This is also documented in the OVM reference manual.

As I said, look at xbus_monitor.sv file and "search" for begin_tr() and end_tr(). All you need is call these function around your protocol code in driver or monitor in order to perform transaction recording.

Run xbus example with this command: "irun -compile_ius.f -gui -ovm". The transactions will show up in SimVision design browser under "ovm_test_top->xbus_demo_sve0->...->monitor". Send the transactions to waveform viewer. If it is still unclear then drop me an e-mail with your phone number, I will call you.
