+
+<p>Coretest system for testing FPGA based entropy source.</p>
+
+<h2>Introduction</h2>
+
+<p>This project is a coretest system dedicated to test entropy sources
+within a FPGA device. The specific entropy source is based on a digital
+oscillator design by Bernd Paysan. In this entropy source, we use six
+instances with different frequencies. The oscillator outputs are
+combined to generate a bit value. 32 bit values are combined to create a
+random word.</p>
+
+<p>The system uses the coretest module to read and write 32-bit data to
+core, In this case it allows a caller to read generated random 16-bit
+values from the entropy source. The 16 bit data is in the LSB of the
+word.</p>
+
+<p>The completc system contains a UART core for external access. The
+project contains pin assignments etc to implement the system on a
+TerasIC C5G board.</p>
+
+<h2>Implementation details.</h2>
+
+<p>This FPGA system consists of the following components:</p>
+
+<ul>
+<li>The FPGA entropy source core</li>
+<li>The UART core</li>
+<li>The coretest core</li>
+</ul>
+
+<p>There are pin assignments and clock defines for the TerasIC C5G board.</p>
