Version 10.0.0 (2006-11-05)

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

Website: http://ruby-vpi.rub...

Install: gem install ruby-vpi

Summary

This release adds the ability to access a handleâ??s children
and reduces the amount of code produced by the automated
test generator.

Acknowledgment

Thanks to Matt Fischler for finding the problem of
misdirected compilation errors in Verilog benches.

Notice

â?¢ The way in which Ruby-VPI and generated tests interact
has changed: the design is now a VPI handle object and
the design.rb and proto.rb files define singleton
methods for that object.
â?¡ I suggest that you regenerate your existing tests
(just run generate_test.rb again) whilst employing
the service of a text merging tool (see the user
manual).

â?¢ You can now access a handleâ??s children by simply
calling methods on it. In the event that a child handle
has the same name as a VPI property, the child is given
priority. However, you can always access VPI properties
explicitly via the get_value and put_value methods.

â?¢ generate_test.rb no longer accepts the -s and -u
options. Use their longer counterparts --rspec and
--xunit instead.

Detail

Automated test generator

â?¢ Generated Verilog benches no longer divert compilation
errors from Verilog design files. That is, if the
Verilog simulator finds compilation errors in a Verilog
design file, it will report that the Verilog design
file is at fault (instead of reporting that the
generated Verilog bench is at fault).

â?¢ The user is now notified when a backup of an existing
file is made.

â?¢ Generated tests have been greatly simplified to reduce
the amount of work for the user.
â?¡ The design is now just a handle to the module in
the Verilog bench.
â?¡ include Vpi and @design are no longer generated.
â?¡ The tutorial and examples have been updated
accordingly.

User manual

â?¢ Revised the stylesheet to make disjoint sections
readily distinguishable from eachother, through
generous spacing and minor coloring.

â?¢ Added tips about ruby-vpi/runner_proxy, rake -T, and
using kdiff3 with generate_test.rb.

â?¢ Moved installation information into a new â??setupâ?
chapter.
