How to generate pseudo random number in FPGA? Marty This has been covered (I'd go for an LFSR): Random number generation on Spartan-3E There's an excellent Xilinx application note on generating pseudo-random number sequences efficiently in an FPGA. It's XAPP052 . If it's not for cryptography or other applications with an intelligent adversary (e.g. gambling) I'd use a linear feedback shift register approach. It only uses exclusive or and shift, so it is very simple to implement in hardware. As others have said, LFSRs can be used for pseudo random numbers in an FPGA. Here is a VHDL
