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.

Hi

I'm trying to simulate some systemc code with nclaunch. I used the example code from the "NC-SC CVE Library Engineering Notebook". When I start compiltation and so on with the ncsc_run command or the irun command I get the following error:

ncelab: *F,SCILDD: Could not load SystemC model library libncsc_model (ld.so.1: ncelab: fatal: relocation error: file: ./libncsc_model.so: symbol _ZN7display14displaySignalsEv: referenced symbol not found).

Has anybody an idea were this error comes from and how I can solve it?


Thanks in advance.

Thomas

Hi Thomas,

This error usually occurs when different compilers are used to create different shareable objects or if some shareable objects were compiled using 32-bit software and some were compiled using 64-bit software.

Take a look at how your environment has been configured and make sure that the same compiler is used to compile all of your code.

Regards,
Gary

Hi Gary,

thanks for your reply. I solved the problem. It was a very stupid error of me ;-) and had, in my case, nothing to do with different compilers.

I implement the example from the notebook and started the 4Bit-counter example with the command that was written in the example: "ncsc_run test.cpp -top test". I thought the program compiles now the test.cpp file and all other files which were included (display.cpp, counter.cpp). But it wasn't so. I had to change the command to: "ncsc_run test.cpp display.cpp counter.cpp -top test". After this all files were compiled seperatly.

Now the compiler showed me a little syntax error in the display.ccp. I think this error was the reason for the SCILDD error because the programm was not able to compile all files. But the program did not tell me this compilation error in the first case were I only started ncsc_run with the test.cpp.

Regards

Thomas
