The grading coefficient affects the diffusion capacitance. The equations are shown at SPICE-compatible diode - MATLAB (mathworks.com) in the Junction Charge Model section. Allowing the grading coefficient to become larger than 0.9 is unphysical, so many SPICE tools have historically enforced this limit in order to avoid unphysical results where the diffusion charge behaves opposite to how it should. The SPICE Diode in Simscape Electrical was written in order to be consistent with the SPICE2 definition.
