[cadence:hspiceD] subckt netlist -parameter passing problem

cadence symbol hspiced

I use hspiceD simulator for generating hspice netlist( IC5141 ).

My netlist has a big problem in subckt definition.

I want like below

-----------------------------------------------------------------------------------

.subckt inv_p a y inh_vdd inh_vss pw=default_value nw=default_value

-----------------------------------------------------------------------------------

but netlist is generated like below

-------------------------------------------------------------------------------------

.subckt inv_p a y inh_vdd inh_vss

------------------------------------------------------------------------------------

****************************************
in schematic, I declare "w" as pPar("pw")

and symbol has pw CDF property

******************************************

parameters do not show on the .subckt row, but the width of mosfet should be replaced with the value of pw.
