<p class="admonition-title">Hint</p>
<p>Most of the examples expect the simulator to support several VHDL 2008 features.
This is made explicit by using <code class="docutils literal notranslate"><span class="pre">context</span></code> instead of multiple <code class="docutils literal notranslate"><span class="pre">use</span></code> statements.
However, some vendors do support enough VHDL 2008 features in order to run some of the examples, but they cannot
handle contexts.
In those cases, replacing <code class="docutils literal notranslate"><span class="pre">context</span> <span class="pre">vunit_lib.vunit_context</span></code> with the content of <a class="reference external" href="https://github.com/VUnit/vunit/tree/master/vunit/vhdl/vunit_context.vhd/">vunit/vhdl/vunit_context.vhd</a>
