ADE Simulation cannot find parameter values from Veriloga module

Dear all, 

I have a Veriloga module that has a bunch of parameters defined. 

Let's say: 

parameter real x = 1.0;

parameter real y = 1.0;

parameter real z = 2*x;

When I create a schematic-based testbench and try to run ADE L, it asks me to manually enter the values of parameters that have been used to define other parameters. 

For example, for the above-defined parameters, it will ask to manually enter the values of x and z. 

Is there a way to make the tool automatically locate those parameters and substitute their values?

I tried to use VAR("variable_name") in CDF Parameter of View in the Edit Object Properties window of the module, but that didn't work.

Your help is much appreciated!
