Parameterized class declaration error in UVM

Question

I'm trying to use a parameterized class extended from uvm_object.

class som_util #(int entry_w=2) extends uvm_object;
 `uvm_object_utils(som_util)
 "Some other static functions using the parameterized variables"
endclass

When I run my tests on IUS using this utility function, it compiles and the overall tests passes too. But on VCS , it complains with the Identifier "entry_w" is not defined ?

What could be the possible reason ?

Answer 1

Parameterized classes in the UVM must be registered using the uvm_object_param_utils macro as below:

 `uvm_object_param_utils(som_util#(entry_w))
