Ruby-VPI is a Ruby interface to IEEE 1364-2005 Verilog VPI.
It lets you create complex Verilog test benches easily and
wholly in Ruby.



Version 14.0.0 (2006-12-30)


This release adds support for simulation callbacks, renders
Verilog benches fully simplified, and revises the user
manual to reflect major changes.


  • The Vpi::relay_verilog method has been replaced by

    Please update you tests accordingly, because invoking
    the Vpi::relay_verilog method directly will cause your
    tests to freeze/hang.

  • Verilog benches no longer contain any clock generation
    code. They are now mere skeletons, whose only purpose
    is to instantiate the design under test.

    The clock generation code is now contained in the Ruby

New features

  • The RubyVpi::init_bench method now gives you complete
    control over performing a clock/operation/whatever
    cycle for your design. This feature allows you to work
    with multi-clocked designs.

  • Callbacks are now supported through the
    Vpi::vpi_register_cb method. See the callbacks section
    in the user manual for details.

  • Added the Vpi::advance_time method, which makes the
    Verilog simulator simulate a given number of time

  • Added the Vpi::simulation_time method, which gives you
    the current simulation time as a 64-bit integer.


  • Removed the monkey patch for the SWIG va_list
    problem—it no longer occurs.

  • Cleansed the appearance of the user documentation.
      â–¡ Added indices to section headings, just like LaTeX.
      â–¡ Admonition boxes no longer interfere with
        surrounding text, and they don’t have big gap above
      â–¡ Navigation menu is now elastic (fluid layout).

  • Revised the user manual and added new content.
      □ Moved “VPI utility layer” section from background
        chapter into usage chapter in user manual.
      â–¡ Added a nice introduction to entire manual with
        links to reference documentation.
