You can use the input as an offset for a fast running counter in your FPGA.

are you talking about on an FPGA or for a simulation?

no FPGA...
simulation onlyy..

The ieee.math_real library has a procedure called 'uniform' that returns a number from 0 to 1. Scale and offset to fit the range that you happen to need.
