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.
Install: gem install ruby-vpi
This release adds the ability to access a handleâ€™s children
and reduces the amount of code produced by the automated
Thanks to Matt Fischler for finding the problem of
misdirected compilation errors in Verilog benches.
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
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
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
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€œsetupâ€
