AMS netlist with CDF parameter

Hi 

I create a cell with "symbol" and "systemverilog" views, and then added one CDF parameter through "Tools->CDF->Edit".

When I config a config, use "systemverilog" view for then cell, then netlist out through AMS UNL netlister, But I don't see the parameter on the cell instance in netlist.vams

Can you suggest how can I netlist out with CDF parameters?

Thanks
