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

SVN tag: svn://rubyforge.org/var/svn/ruby-vpi/tags/0.9.2

Version 0.9.2 (2006-08-26)

Summary

```
This release beautifies generated tests, adds checks to find
signal width bugs, and includes a new tool.

```

Details

â?¢ The test generator now uses ERB templates which ensures nice  
indentation of generated output.

â?¢ The test generator now decouples Ruby-VPI paths from Verilog  
benches via the RUBYLIB environment variable.

â?¢ A tool which converts Verilog headers into Ruby has been added.

â?¢ put\_value() now returns the value it puts. Therefore, it is  
easier to chain together a series of assignments:

```
  foo.intVal = bar.intVal = baz.intVal = 10

```

â?¢ put\_value() now verifies that the value it puts was written  
correctly. This helps to find bugs regarding invalid  
assumptions about the number of bits supported by a signal.

â?¢ The source code is now indented with two spaces instead of one  
tab character.
