I don't know, in my domain what I can do the best is to spend the tiny time step = 1ps. (already the smallest when considering the computing performance.)
But neither LTspice nor Matlab/simulink has the expected answer. (Thay have the same output ~ 40mV)
?
About the algorithm inside transfer function, I really have no idea, maybe not enough decimal digits been calculated. Can't find any where to configure that.

Best regards.

The transfer function and time domain expressions look OK to me but the scope plot is obviously "wrong".
This could be caused by the sample-based Simulink implementation. What is the sample-rate / solver
algorithm? If there is aliasing all three representations could be correct.
