This article discusses how to include pseudorandomness and true randomness in LTspice® simulations using the flat(), gauss(), and mc() functions, as well as how to use the Use the clock to reseed the MC generator option in the Hacks section of the settings panel. Trade-offs between pseudorandomness and true randomness are discussed, as well as trade-offs between statistical, Monte Carlo-like simulations and more targeted worst-case simulations.
