  1. i want to know the the relation between histogram and the simulation value. Does it mean the probability of 1 of specific bit position?
  2. why the histogram will shift to the right for 1 bit when I clearing Signed option?

Hi,
The histograms in quantization workflows put each value observed in simulation in a power of two bin.
For example, the values 1.25, 1.51234, and 1.75 are all in the power of two bin from 2 to 4.
The values -4.7, -5.9, and -7.8765432 are all in the power of two bin from -8 to -4.
This documentation page does a very nice job of explaining histogram bins in quantization workflows.
