Overview
Generates randomized sequences of integers.
Discussion
This module generates randomized sequences of integers. The randomness comes from pseudo-random number generator typically used in computer programs. The randomized sequence may contain duplicates. Two output pins are provided: A and B outputs each a half of the sequence. Reset pin reshuffles the sequence vector. Increment control input pins select the next value from the sequencer vector. Only an inc value higher than the prior one will generate a new value at the output.
