I don&#x27;t think I&#x27;ve asked for anything particularly unusual?<p>It&#x27;s common for electronics manufacturers to release diagrams like this: <a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;k6o8mwO.png" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;k6o8mwO.png</a> detailed enough to give you an idea of how the circuit behaves and why, but well short of a complete internal schematic for the entire device.<p>Google &quot;Xilinx FPGA cell&quot; <a href="https:&#x2F;&#x2F;www.google.co.uk&#x2F;search?tbm=isch&amp;q=xilinx+fpga+cell" rel="nofollow">https:&#x2F;&#x2F;www.google.co.uk&#x2F;search?tbm=isch&amp;q=xilinx+fpga+cell</a> and you&#x27;ll find similar approximate diagrams exist for FPGA cells. That&#x27;s the detail level I&#x27;m interested in, and I think it&#x27;s reasonable enough to believe it would exist?
