Parameterize a Piecewise Linear Diode Model from a Datasheet

I'm not sure why the author chose 0.6 as the forward voltage and 0.1 as the drop voltage, when the datasheet provides 0.7 V as the forward voltage.

Does the voltage drop across the diode have to be assumed here?

Here is a link to the mathworks documentation on the topic

For this case forward voltage is 0.7V when the forward current is 5mA. Forward voltage is not actually a fixed value. The piecewise linear Diode block in Simscape Electrical defines Vf as the ‘Minimum voltage that needs to be applied for the diode to become forward-biased.’ We need two values for the forward voltage to compute the voltage drop and the diode on resistance, the minimum and the value at a given current. I hope this helps.
