Version 12.1.0 (2006-12-22)

Summary

This release adds interactive debugging support, adds new  
sections to the user manual, and cleanses some internals.

Notice

• The lib/ruby-vpi/rspec.rb and lib/ruby-vpi/xx.rb files  
has been removed because they are no longer necessary.

• rSpec 0.7.0 or newer is now required because the sample  
tests utilize the should == syntax—which was introduced  
in rSpec 0.7.0.

Detail

• Test runners now support the DEBUG environment  
variable, which enables the interactive debugger  
(ruby-debug) in post-mortem debugging mode.  
â–¡ The debugger can now be used when DEBUG environment  
variable is not activated.  
â–¡ ruby-debug is now a gem dependency for Ruby-VPI.

• Status messages, which are shown during initialization  
of a Ruby bench, now appear in simulators’ log files.

• Added documentation about test runners and the  
interactive debugger in the user manual.

• Added a README file with hint about where to find the  
user manual.

• Removed code that wasn’t being used, according to code  
coverage analysis, from the pipelined ALU sample.
