Ruby-VPI is a Ruby interface to Verilog VPI. It lets you create  
complex Verilog test benches easily and wholly in Ruby.

Install: gem install ruby-vpi

Version 11.0.0 (2006-11-05)

Summary

This release shortens generated Ruby benches and uses the  
less confusing notation for defining singleton methods in  
generated designs and prototypes.

Notice

• The arguments for the RubyVPI.init\_bench method have  
changed.

• generate\_test.rb no longer emits undocumented status  
indicators: name and format.

• The source code is no longer distributed as a zip  
package, because it seems to be quite underutilized in  
comparison to the tgz and gem packages.

Detail

• Generated Ruby benches have been shortened to just one  
line of code!

• The less confusing notation of

```
def some_object.a_singleton_method
  do_stuff
end

is now used instead of the

class << some_object
  def a_singleton_method
    do_stuff
  end
end

notation.
  â–¡ The tutorial and examples have been updated
    accordingly.

```

• The pipelined ALU example now has an updated  
IntegerGenerator class.
