How to generate White Gauss noise for Random Road Profile as per ISO 8608?

I am trying to simulate Random Road Profile Grade-C as per ISO 8608 usin Shaping Filter Method equation (Eq. 15 of attachement). The value of "Alpha" is taken as 0.127 from Table.3 shown in attached image, "Velocity of vehicle, v = 20 m/s". But as per Simulink Model "Random Number Block" is used for generating "Gaussian White Noise". The block requires 4 inputs i.e. "Mean", "Variance", "Initial SEED" and "Sample Time".
The "Mean" is taken as "0" , "Sample Time" is taken as Simulation fixed step time i.e. 0.001. Now I have no clue what value will be used for "Variance" and "SEED"? for this white noise.
Will this "variance" be Square of "Sigma" from Table 3? or some thing else?
