The collector +observes positive flank events in the input noise signal and measures the +time between these events using a counter. The counter is free running +and increases once for each clock cycle (currently running av 50 MHz).</p> + +<p>The LSB of the counter is added to a 32-bit entropy register at each +event.</p> + +<p>As debug output the entropy register is sampled at a given rate +(currently a few times per second). The debug output is connected to LED +on the FPGA development board.</p> + +<p>The project also contains project files, pin assignments and clock +definition neded to implement the design on a TerasIC DE0-Nano board.</p> +``` + +[[RepositoryIndex(format=table,glob=test/external_avalanche_entropy)]] + +| Clone `https://git.cryptech.is/test/external_avalanche_entropy.git` | +|---| |
