Simple example of passing classes between nc and Specman

Hi,
Interesting trial indeed. I must admit I don't know the answer really, but looking at the code I see that your E-struct name is "dut_instruction" whereas inside SV you have:

import specman_types::*; sn_dut_instruction ins;

Is this how it is supposed to be as per manual? Or is it a typo?

Also can you elaborate on what you mean by:

but that doesn't seem to work.

Hi Ajeetha,
Thanks for your answer.

The example was copied as is from:

http://sourcelink.cadence.com/docs/files/Release_Info/Docs/sn_beta/sn_beta6.1/sn_beta.pdf

pages 35-36.

I believe the name mismatch is due to the fact that in between the e code and the sv code, you have the automatically generated stubs file, that probably fiddles a bit with the type names, and prefixes them with "sn_"

"that doesn't seem to work" is in fact too general...it means that the automatically generated stubs file (specman.svh) gives compilation errors when compile with ncvlog -sv.

Hi Avidan

We couldn't recreate your compilation error, we've ran the attached script, and it passed compilation phase.
Which Specman and IUS versions do you use?
Also, please attach the ncvlog.log file that is created when you try to compile the specman.svh file.

Thanks

Hi Erez, I'm using Specman and ncvlog 6.20. The script output and the ncvlog.log file are attached. Best, Avidan

Hi Aviad

It seems that the INCA_libs already includes some of the SV environement generated by Specman.
(Have you ran this example also with irun ?)
Delete the existing INCA_libs, and rerun the compile script.

Hi Erez,
Thanks, you're right. It works now.
