While experimenting with simulation of some filter circuits for digitised data, I amused myself by creating a simple model of a quantised signal generator to test the circuits (I know, I should get out more 
).
In case it's of use to anyone else I've attached the .asy and .sub files for the model.
The model has two user-specified parameters:
1) a value 'Bits' to define the bit-width of the digital data (e.g as fed to a DAC),
2) a value 'Fsv' to define the full-scale voltage corresponding to the number 2^Bits.
Here are a couple of examples of the model use:
