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)
Summary
This release adds support for simulation callbacks, renders
Verilog benches fully simplified, and revises the user
manual to reflect major changes.
Notice
• The Vpi::relay_verilog method has been replaced by
Vpi::simulate.
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
bench.
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
steps.
• Added the Vpi::simulation_time method, which gives you
the current simulation time as a 64-bit integer.
Details
• 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
them.
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.
