Hi,
you have to first develop an EM model of the via, together with the 
planes in HFSS. Use feeding lines to connect the via to the wave ports. 
Assign materials to the model, define the ports and set up the 
convergence criteria (e.g., maximum delta_S). At the end of the field 
simulation, remove the effects of the feeding lines through 
de-embedding. You can now use the resulting S-parameters to extract the 
electrical parameters (e.g., inductance, capacitance,...) of the via. 
One way of doing this is to use a circuit simulator (e.g., Serenade from 
Ansoft, ADS,...). Based on the extracted S-parameters, develop and 
equivalent circuit model of the via and through optimization, these 
electrical parameters can then be obtained.

Best regards,
Ivan Ndip
