A major potential problem with the LFSR approach is that some logic, such as an NA810 (an 8-input NAND gate), is pattern resistant. When any of the eight inputs is a 0, the output is a 1. Only when all eight inputs are 1s does the logic change stat

利用LFSR來產生出random的數字讓FPGA能一直出現亂數-using LFSR to complete the random number
