<li>3 <a href="#anchor3">Obsolete tasks</a></li>

</div>
<h1 id="anchor1">1 Pending tasks</h1>
<ul>
<li>add shortcuts for reading & writing <span class="caps">VPI</span> delay values</li>
</ul>
<ul>
<li><span class="caps">GHDL</span> simulator supports <span class="caps">VPI</span>
<ul>
<li>need way to invoke <span class="caps">VPI</span> tasks from <span class="caps">VHDL</span>, like <code class="code"><span style="color:#d70; font-weight:bold">$ruby_init</span>();</code>
<p><ins>No need for system tasks/functions. Ruby-VPI uses callbacks now!</ins></p></li>
</ul></li>
</ul>
<ul>
<li>add instructions for using <strong>ruby-debug</strong> with a graphical debugging tool or <span class="caps">IDE</span> like RadRails</li>
</ul>
<ul>
<li>write section about code coverage and prototyping in manual</li>
</ul>
<ul>
<li>clean up the teriminology section… unnecessary</li>
</ul>
<h1 id="anchor2">2 Finished tasks</h1>
<ul>
<li>add support for <span class="caps">ESL</span> prototyping (like SystemC)</li>
</ul>
<ul>
<li>decouple code generation with $RUBYLIB and erb</li>
</ul>
<ul>
<li>change should_be to should_equal in examples</li>
</ul>
<ul>
<li>add support for <span class="caps">GPL</span> Cver in the test runner template</li>
</ul>
<ul>
<li>build ruby-vpi once to generate all .so files
<ul>
<li>test runner should not rebuild ruby-vpi every time</li>
</ul></li>
</ul>
<ul>
<li>distribute as a <span class="caps">GEM</span>, binary, and source
<ul>
<li>use <span class="caps">RUBYLIB</span> to bypass rubygems site installation for local testing. otherwise have to build & install gem <em>every</em> time!</li>
<li>move stuff from lib/ into lib/ruby-vpi/</li>
</ul></li>
</ul>
<ul>
<li>integrate RCov for code-coverage statistics</li>
</ul>
<ul>
<li>method_missing for Design class</li>
</ul>
<ul>
<li>define handled methods in Vpi::method_missing for faster response
<ul>
<li>this has been verified as bottleneck from profiling data</li>
</ul></li>
</ul>
<ul>
<li>make RCov correctly profile the code and report useful coverage metrics…</li>
</ul>
<ul>
<li>add support for <span class="caps">VPI</span> callbacks which execute Ruby blocks</li>
</ul>
<h1 id="anchor3">3 Obsolete tasks</h1>
<ul>
<li>smarter test generation, which adjusts to user modifications in previously generated output
<p><ins>Just use a smart merging tool like <strong>kdiff3</strong>.</ins></p></li>
</ul>
<ul>
<li>interactive console <span class="caps">IRB</span> wrapper for spec (just like Breakpoints in Rails)
<p><ins>Use the <strong>ruby-debug</strong> library with <a href="http://www.datanoise.com/articles/category/ruby-debug"><strong>debugger</strong> command for breakpoints</a> instead!</ins></p></li>
</ul>
<ul>
<li>need to dump signal values when expectation fails in rSpec
<p><ins>You can use the interactive debugger instead.</ins></p>
<ul>
<li>maybe a waveform dump will also help
<p><ins>After reading some <span class="caps">RTL</span> verification books, this is not necessarily true.</ins></p></li>
</ul></li>
