+External Avalanche Entropy
+--------------------------
+This is a test project of an entropy provider that collects entropy from
+an avalanche noise based source.
+
+The design expects a one bit digital input noise signal. 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).
+
+The LSB of the counter is added to a 32-bit entropy register at each
+event.
+
+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.
+
+The project also contains project files, pin assignments and clock
+definition neded to implement the design on a TerasIC DE0-Nano board.
