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. + +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. + +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. + +## Implementation details. ## +This FPGA system consists of the following components: + +- The FPGA entropy source core +- The UART core +- The coretest core + +There are pin assignments and clock defines for the TerasIC C5G board. diff --git a/toolruns/quartus/terasic_c5g/output_files/coretest_fpga_entropy.sof b/toolruns/quartus/terasic_c5g/output_files/coretest_fpga_entropy.sof new file mode 100644 index 0000000..97e79ba Binary files /dev/null and b/toolruns/quartus/terasic_c5g/output_files/coretest_fpga_entropy.sof differ -- cgit v1.2.3
