We introduce a new method for the design of information entropy sources in Programmable Logic Devices (PLDs), based on a novel class of circuits called Digital Nonlinear Oscillators (DNOs) supporting complex dynamics, including chaos. Following this method, we designed a fully digital entropy source, i.e. entirely described in VHDL. The solution has been implemented on a Xilinx FPGA, showing, according to some tuning, periodic and chaotic behaviors.
