h1. Pending tasks

* add support for reading & writing VPI delay values

* GHDL simulator supports VPI
** -need way to invoke VPI tasks from VHDL, like @$ruby_init();@-
No need for tasks; Ruby-VPI uses callbacks now!

* add instructions for using *ruby-debug* with a graphical debugging tool or IDE like RadRails

* write section about code coverage and prototyping in manual

* clean up the teriminology section... unnecessary


h1. Finished tasks

* add support for ESL prototyping (like SystemC)

* decouple code generation with $RUBYLIB and erb

* change should_be to should_equal in examples

* add support for GPL Cver in the test runner template

* build ruby-vpi once to generate all .so files
** test runner should not rebuild ruby-vpi every time

* distribute as a GEM, binary, and source
** use RUBYLIB to bypass rubygems site installation for local testing. otherwise have to build & install gem _every_ time!
** move stuff from lib/ into lib/ruby-vpi/

* integrate RCov for code-coverage statistics

* method_missing for Design class

* define handled methods in Vpi::method_missing for faster response
** this has been verified as bottleneck from profiling data

* make RCov correctly profile the code and report useful coverage metrics...

* add support for VPI callbacks which execute Ruby blocks


h1. Obsolete tasks

* -smarter test generation, which adjusts to user modifications in previously generated output-
Just use a smart merging tool like *kdiff3*.

* -interactive console IRB wrapper for spec (just like Breakpoints in Rails)- Use the *ruby-debug* library with "*debugger* command for breakpoints":http://www.datanoise.com/articles/category/ruby-debug instead!

* -need to dump signal values when expectation fails in rSpec-
You can use the interactive debugger instead.
** -maybe a waveform dump will also help-
After reading some RTL verification books, this is not necessarily true.
