+[Somebody asked about using XSPICE components](https://github.com/xesscorp/skidl/issues/76) in SPICE simulations with SKiDL.
+That wasn't possible since [PySpice](https://pyspice.fabrice-salvaire.fr/) didn't really support these when I [built the interface](https://xesscorp.github.io/skidl/docs/_site/blog/spice-simulation).
+So I added XSPICE parts to the [SKiDL SPICE interface](https://github.com/xesscorp/skidl/blob/master/examples/spice-sim-intro/spice-sim-intro.ipynb) and released it as [SKiDL 0.0.29](https://pypi.org/project/skidl/).

+    &lt;p&gt;&lt;a href=&quot;https://github.com/xesscorp/skidl/issues/76&quot;&gt;Somebody asked about using XSPICE components&lt;/a&gt; in SPICE simulations with SKiDL.
+That wasn’t possible since &lt;a href=&quot;https://pyspice.fabrice-salvaire.fr/&quot;&gt;PySpice&lt;/a&gt; didn’t really support these when I &lt;a href=&quot;https://xesscorp.github.io/skidl/docs/_site/blog/spice-simulation&quot;&gt;built the interface&lt;/a&gt;.
+So I added XSPICE parts to the &lt;a href=&quot;https://github.com/xesscorp/skidl/blob/master/examples/spice-sim-intro/spice-sim-intro.ipynb&quot;&gt;SKiDL SPICE interface&lt;/a&gt; and released it as &lt;a href=&quot;https://pypi.org/project/skidl/&quot;&gt;SKiDL 0.0.29&lt;/a&gt;.&lt;/p&gt;
