Random number generator (4/8 bit)

VHDL implementation of random number generator from 0 to 15 (4 bits). The random number is displayed on LED vector display on FPGA. Implemented on Xilinx Spartan 6 FPGA.

Press push button on FPGA to generate 4 bit random number. It can show anything from (0000 to 1111).

Random number generation is done by continuous XOR operation of bit vector at clock pulses.
