<p>Squishy is a set of utilities, gateware, and hardware for interacting with and developing things related to SCSI.</p>
<p>Once you’ve read the sections below and are ready to get started, see the <a class="reference internal" href="install.html"><span class="std std-doc">Installation</span></a> and the <a class="reference internal" href="getting_started.html"><span class="std std-doc">Getting Started</span></a> sections.</p>
<section id="overview">
<h2>Overview<a class="headerlink" href="#overview" title="Link to this heading">¶</a></h2>
<p>Squishy has many moving parts, the following diagram illustrates a rough overview of how
everything in the Squishy system interacts.</p>
<p><img alt="" src="_images/squishy-arch-overview.svg" /></p>
</section>
<section id="hardware">
<h2>Hardware<a class="headerlink" href="#hardware" title="Link to this heading">¶</a></h2>
<p>The Squishy hardware is a bespoke physical interface into the world of SCSI. Out of the box, it provides a way to inspect and interact with the world of SCSI, be it HVD, LVD, or Single-Ended, all from a modern machine over USB.</p>
<p>Combined with the software, it provides and out-of-the box way of inspecting traffic on a SCSI bus, as well as capturing the traffic for analysis or even replay!</p>
<p>With the power of <a class="reference external" href="https://github.com/shrine-maiden-heavy-industries/torii-hdl">Torii</a>, you can also write your own <a class="reference internal" href="applets/index.html"><span class="std std-doc">applets</span></a> to do things such as emulate devices, or hosts, or anything else you could imagine.</p>
<p>For more information on the Squishy hardware, see the <a class="reference internal" href="hardware/index.html"><span class="std std-doc">Hardware</span></a> section in the documentation.</p>
</section>
<section id="software">
<h2>Software<a class="headerlink" href="#software" title="Link to this heading">¶</a></h2>
<p>The Squishy software is a set of utilities that allows for interacting with the Squishy hardware, and a <a class="reference internal" href="library/python/index.html"><span class="std std-doc">Python library</span></a> that allows for developers of Squishy applets and other applications to parse SCSI traffic and interact with SCSI devices.</p>
<p>For more information on the software, see the <a class="reference internal" href="cli.html"><span class="std std-doc">CLI</span></a> section as well as the Python library documentation.</p>
</section>
<section id="gateware">
<h2>Gateware<a class="headerlink" href="#gateware" title="Link to this heading">¶</a></h2>
<p>The Squishy gateware works in combination with the hardware to allow for the rapid and flexible development of devices that can be used to interact with various SCSI devices.</p>
<p>The <a class="reference internal" href="library/gateware/index.html"><span class="std std-doc">gateware library</span></a> allows for applets to be built on the Squishy platform, and for other devices that wish to leverage SCSI in some aspect of their design to do so with <a class="reference external" href="https://github.com/shrine-maiden-heavy-industries/torii-hdl">Torii</a>.</p>
<p>For more information, see the <a class="reference internal" href="library/gateware/index.html"><span class="std std-doc">gateware library</span></a> documentation.</p>
