xilinx edk6.2.03i simulation with ncsim

Hi,has anyone used ncsim for simulation with edk6.2.03i? I am having
trouble finding the precompiled edk cores (e.g. microblaze) for ncsim.
The documentation states that ncsim is supported, but the compedklib
utility complains that it can't find any precompliled cores nor does
any thing resembling it exists anywhere in the EDK installation.
Thanks in advance for any help.

Have you tried `compedklib --help` ?

Use Case I: Compiling HDL sources in the built-in repositories in
the EDK

The most common use case is as follows:

compedklib -o <compedklib-output-dir-name>
-X <compxlib-output-dir-name>

In this case the 'pcores' available in the EDK install are compiled
and the stored in <compedklib-output-dir-name> . The value to the
'-X' option indicates the directory containing the models outputted
by 'compxlib'. such as the 'unisim', 'simprim' and 'XilinxCoreLib'
compiled libraries.

Does that work?

Hi John,
Thanks for your advice. I did look up compedklib --help before, along
with the info that is contained in the platform_studio_ug.pdf under
the compiling EDK behavioral simulation libraries section. Here is a
more detailed description of the problem.

The exact compedklib command that I used is

compedklib -s ncsim -o output-dir-name -X compxlib-output-dir-name

I was able to run the compxlib utility successfully earlier, which
generated ncsim compiled libraries for unisim, simprim, and
XilinxCorelib. The -X option is pointing to the corresponding xilinx
libraries directory.

The above compedklib gave me the following error message at the prompt

Scanning repositories for pcores ...
10 pcores located with (0) errors
20 pcores located with (0) errors
30 pcores located with (0) errors
40 pcores located with (38) errors
See compedklib.log for execution log.
Exiting: too many errors


The log file contains many lines that looks like the following

ERROR::Cannot locate pre-compiled library microblaze_v1_00_c

I also looked into the resulting output directory. It only contains
many empty sub directories.


I tried to look for the pre-compiled library for ncsim because
according to compedklib --help

Some 'pcores' are secure in that their source code is not
available.
In such cases, the repository contains the compiled
models. These are copied out into <compedklib-output-dir-name>

and the microblaze vhdl source files in the pcores directory are
encrypted. I only found the compiled models for the mti version under
EDK/hw/XilinxProcessorsIPLib/CompiledModels. Nothing similar for
ncsim was found. That is why I am confused. If simulation with ncsim
is supported as according to the documentation, then where are the
precompiled libraries for the EDK?

Thanks again.

Hi John,
Thanks for you help. I did look up compedklib --help before, along
with the info in platform studio user guide under the section
compiling EDK behavioral simulation libraries. Here are some more
detail to my problem.

The exact command that I executed is
compedklib -s ncsim -o compedklib -X compxlib
The compxlib directory contains the ncsim compiled librarys for
unisim, simprim, and XilinxCoreLib. The errors I are got at prompt
are

Scanning repositories for pcores ...
10 pcores located with (0) errors
20 pcores located with (0) errors
30 pcores located with (0) errors
40 pcores located with (38) errors
See compedklib.log for execution log.
Exiting: too many errors

The errors in the log files are all similar to
ERROR::Cannot locate pre-compiled library microblaze_v1_00_c
The output directory contains only empty sub directories.

I tried to find the precompiled libraries for ncsim, but only found
those for mti under EDK/hw/XilinxProcessorIPLib/CompiledModels.

Thanks again

Ah yes I see now what you mean. I'd be contacting Xilinx support on
this one - there's really not much you can do with that encrypted VHDL...
