Quantization, in mathematics and digital signal processing, is the process of mapping input values from a large set (often a continuous set) to output values in a (countable) smaller set, often with a finite number of elements. Rounding and truncation are typical examples of quantization processes.

AWGN model of Quantization Noise
I'm afraid I'm missing big points about quantization noise. … Note that for any value of alpha I can observe quantization noise as 1/sqrt(12) by just taking: std(I-Iq)
It seems I can't measure the final noise as Iq_std_meas = std(Iq). …

AWGN model of Quantization Noise
I'm expecting to be able to model the output noise as Iq_std_model = alpha+1/sqrt(12)
That's the big fundamental point that I was missing.
Standard deviation sums in quadrature, duh!
Using Iq_std_mo …
