<h3>Features<a class="headerlink" href="#id2" title="Link to this heading">¶</a></h3>
<ul>
<li><p>[Questa/Modelsim] Added support for 3-step flow and the Visualizer debugger.</p>
<p>The 3-step flow is enabled by setting the simulation option <code class="docutils literal notranslate"><span class="pre">modelsim.three_step_flow</span></code> to <code class="docutils literal notranslate"><span class="pre">True</span></code>. Extra
flags to the <code class="docutils literal notranslate"><span class="pre">vopt</span></code> step can be provided with the simulation flags <code class="docutils literal notranslate"><span class="pre">modelsim.vopt_flags</span></code> and
<code class="docutils literal notranslate"><span class="pre">modelsim.vopt_flags.gui</span></code> in normal and GUI mode, respectively.</p>
<p>The Visualizer debugger is enabled from the command line using the <code class="docutils literal notranslate"><span class="pre">--debugger=visualizer</span></code> option (in
addition to the <code class="docutils literal notranslate"><span class="pre">--gui</span></code> option for GUI mode). The 3-step flow must be enabled for this feature while
the default <code class="docutils literal notranslate"><span class="pre">original</span></code> debugger works with or without the 3-step flow.</p>
<p>Note: There is a bug in Visualizer preventing the normal <code class="docutils literal notranslate"><span class="pre">restart</span></code> command from being used. Please use the
<code class="docutils literal notranslate"><span class="pre">vunit_restart</span></code> command instead. (<a class="reference external" href="https://github.com/VUnit/vunit/issues/899/">#899</a>)</p>
</li>
<li><p>[GHDL/NVC] Arbitrary waveform viewers are now supported by passing the <code class="docutils literal notranslate"><span class="pre">--viewer</span></code>
command line argument. As a consequence, <code class="docutils literal notranslate"><span class="pre">ghdl.gtkwave_script.gui</span></code> and
<code class="docutils literal notranslate"><span class="pre">nvc.gtkwave_script.gui</span></code> are deprecated in favour of <code class="docutils literal notranslate"><span class="pre">ghdl.viewer_script.gui</span></code>
and <code class="docutils literal notranslate"><span class="pre">nvc.viewer_script.gui</span></code>, respectively. The <code class="docutils literal notranslate"><span class="pre">--gtkwave-args</span></code> and
<code class="docutils literal notranslate"><span class="pre">--gtkwave-fmt</span></code> command line arguments are deprecated in favour of <code class="docutils literal notranslate"><span class="pre">--viewer-args</span></code>
and <code class="docutils literal notranslate"><span class="pre">--viewer-fmt</span></code>, respectively. <code class="docutils literal notranslate"><span class="pre">ghdl.viewer.gui</span></code> and <code class="docutils literal notranslate"><span class="pre">nvc.viewer.gui</span></code> can
be used to set the preferred viewer from the run-file. If no viewer is explicitly
requested, <code class="docutils literal notranslate"><span class="pre">gtkwave</span></code> or <code class="docutils literal notranslate"><span class="pre">surfer</span></code> is used, in that order. This also means that
VUnit now uses <code class="docutils literal notranslate"><span class="pre">surfer</span></code> if <code class="docutils literal notranslate"><span class="pre">gtkwave</span></code> is not installed.</p>
<p>[NVC] It is possible to get VCD waveform files by passing <code class="docutils literal notranslate"><span class="pre">--viewer-fmt=vcd</span></code>. (<a class="reference external" href="https://github.com/VUnit/vunit/issues/1002/">#1002</a>)</p>
</li>
<li><p>Added timeout parameter to the <cite>wait_until_idle</cite> procedure in the synchronization verification component interface.
A timeout will result in a failure. (<a class="reference external" href="https://github.com/VUnit/vunit/issues/1054/">#1054</a>)</p></li>
