The invention discloses a high-counting-rate and high-randomness simulated nuclear signal generator which comprises a random number generation module, an amplitude conversion module, a white noise generation module, an impact sequence generation module and a waveform forming and output correction module. The random number generation module comprises a clock and a linear feedback shift register, the amplitude conversion module comprises a Block RAM (Random Access Memory), the Block RAM is used for storing an amplitude conversion mapping table, the white noise generation module realizes Box-Muller coordinate rotation transformation through joint calculation of a plurality of CORDIC IP (Intellectual Property) cores, and the input pseudo-random number is subjected to Box-Muller coordinate rotation transformation and then outputs a normally distributed noise sequence; and the impact sequence generation module receives the pseudo-random number output by the random number generation module and the amplitude random s
