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> +``` + +[[RepositoryIndex(format=table,glob=test/coretest_fpga_entropy)]] + +| Clone `https://git.cryptech.is/test/coretest_fpga_entropy.git` | +|---| |
