[myhdl-list] migrating from myHDL-0.5.1 to myHDL_0.6

[Sami Al D. <sam...@gm...>]

Dear All,
I think there should be a guide for migrating from myHDL-0.5.1 to 0.6 in
linux and windows. Further more the manual should contain examples on the
new features.

The What's New document is supposed to document the new features:
   http://www.myhdl.org/doc/0.6/whatsnew/0.6.html

For migration, I think the most important section is the one on
backwards incompatible changes:

http://www.myhdl.org/doc/0.6/whatsnew/0.6.html#backwards-incompatible-changes

The most important features are conversion to VHDL and enhancements
to the convertor capabilities. Consequently, the chapter on conversion
has been rewritten completely:

     http://www.myhdl.org/doc/0.6/manual/conversion.html

Moreover, there is a new chapter dedicated to conversion examples,
both in Verilog and in VHDL:

     http://www.myhdl.org/doc/0.6/manual/conversion.html

In the future, more in-depth examples, e.g. about test bench
conversion, will be added to the on-line Cookbook.

Regards,

Jan

Dear Jan,
Thank you for your response. Maybe I should have been more precise, what I
should have said was "installation guide" . I have myHDL 0.5.1 with python
2.5 on Ubuntu, if I want to have the new myHDL 0.6, should I remove the
0.5.1 version or remove a specific files in the bin directory? Thank you for
your time and a job well done in myHDL.

Hi Sami,

The upgrade is Python standard procedure and it depends on how you
installed MyHDL in the first place. If you have a RPM package (assuming
there is one for Ubuntu) you can just run the update process and it will
replace the old files.

If you used the easy_install, there is an update feature.

http://peak.telecommunity.com/DevCenter/EasyInstall#upgrading-a-package

Now with the source installation (python setup.py install) I have to
admit I always did it the rough way, by removing the site-package/myhdl
folder and install the new package. I am not sure whether there is also
something like an update feature?

Cheers,

Guenter

There are no bin files, myhdl is installed as a directory somewhere in
your Python path.

Personally, I always use 'python setup.py install', as for all my
Python packages. Usually I don't even bother to remove the old 
installation, although I admit that would be cleaner. (Note that
for this to go wrong, a package's behavior should depend on the
existence of superfluous files, which is rather strange behaviour.)

[Sami Al D. <sam...@gm...>]

Dear All,

Thank you for your response, it is really helpful especially Gunter's
approach. But for now I think I will go with the straight forward one
suggested by Jan. And I assume I should install the new VPI file of the 0.6
for the cosimulation instead of the old one in the simulator (Icarus in my
case), right?

I really like the analyze/verify features, because they save me the script
used to compile ans simulate the Verilog code. By the way does anyone have
good experience in Icarus (maybe it is somehow unrelated to myHDL but it can
be useful)? I ran into the issue when you have a python script using the
function "os.system(*command*)" to run Icarus for compiling and simulating
then GTKwave for showing the wave diagram, sometimes when you have a syntax
error python just do not realize this and continue the script. Do you if
Icarus can return a value that can be tested for errors that can help my
script? Actually I asked the same question in the Icarus Wiki and they
pointed to a Perl test suite that I can learn from, this requires investing
time to learn Perl then translate it to Python, which is an option I like to
make one my last ones.

Sorry for the long email and thank you for your time reading it.

Just remember that you are simply programming in Python.  Therefore, there
are other ways of calling the command above (whether or not this would be
the right thing to do or not will depend on what you doing).  Look at Popen
in the subprocess module that comes with Python.  You can do try-except
blocks as well etc.

>>> help(os.system)

This will show you that os.system will give you an exit status.

This is the beauty of MyHDL....its in Python!

I thought there was a discussion about that last year or so on the
Icarus mailing list, but the only post I found was this from 2007:

http://www.nabble.com/gEDA-dev:-Icarus-Verilog-return-codes--td8653647.html

However, if I understand you right then you want to know when the
simulation failed, which might not be covered by that return code.

As Newell mentioned in another post, one way to solve that is not to use
os.system() but for example os.popen() instead. There you can read the
output of the application and in the test bench you can write some text
that can be search for in the calling python script.

Hi Sami,

I have separate virtual Pythons for most every tool or combination of tools that
I need.  I use virtualenv to do this and recommend it highly.  Doug Hellmann
even has a nice wrapper, that I also use:
