Subject: NameError when simulating with ncsim
Message-ID: <02b801cb4e61$391801e0$ab4805a0$@no>

Hi,

 

I am fairly new to ruby, but I came across ruby-vpi and I think it looks
very interesting so I thought I would give it a go. After installing
rubygems I installed ruby-vpi and tried to run the example from the
ruby-vpi user guide. 

 

When I run 'rake ncsim PROTOTYPE=1' the simulator crashes with the
following error message:

 

.

[user.c:23] Ruby-VPI: error: rb_require('ruby-vpi/boot/relay') failed with
status 6

[user.c:23] Ruby-VPI: error: rb_require('ruby-vpi/boot/loader') failed
with status 6

ruby: uninitialized constant RubyVPI (NameError)

ncsim: *F,INTERR: INTERNAL ERROR

.

 

I also get a similar message when I run it on the verilog module with
'rake ncsim'. Any idea what I'm doing wrong?

 

I have included all the files I'm using, including the ncverilog log-file.

 

I am running this on Cadence ncsim64 version 09.20-s014, ruby-vpi version
21.1.0 and ruby version 1.8.5.

 

Best regards

 

Nikolaj Andersen

Please try using Ruby 1.8.6 or 1.8.7.  I'm afraid that 1.8.5 is too old.

Hi Suraj,

Thank you for your response! I upgraded ruby to 1.8.7 but I still get the 
same error. I also tried to install Icarus verilog on a different computer 
(Ubuntu this time, the first one was running RHEL 5) but with no luck, I get 
the same error message again..

Then I tried to install an older version of Ruby-VPI. 21.0.0 crashes with 
the same error, but 20.0.0 works a lot better! However, the example didn't 
run right away. It complains about the setup methods in the specification:

counter_spec.rb:27:in `load_test': undefined method `setup' for 
Spec::Example::ExampleGroup::Subclass_2:Class (NoMethodError)

I played around with it and changed 'setup do' --> 'before :each'. Now it 
runs without any complaints, but I'm not very familiar with RSpec so I don't 
know if the two lines actually do the same thing?

-Nikolaj

I highly recommend using GPL Cver instead of Icarus Verilog for Ruby-VPI.

Good find!  Yes, RSpec had a setup() method some years ago, but it was
later changed to before(:each) as you discovered.
