Parameterized sequence

Hi,

I am facing run-time error while creating object for parameterized sequence.
Here is my code:

class multi_req_seq#(parameter int REQ_WD= 16) extends uvm_sequence;
uvm_object_param_utils(multi_req_seq) uvm_declare_p_sequencer(`sequencer_type(REQ_WD))

rra_item#(REQ_WD) stimuli;

function new(string name="");
  super.new(name);
endfunction : new

task pre_start();
  `ifdef UVM_POST_VERSION_1_1
      uvm_phase starting_phase = get_starting_phase();
  `endif
  if(starting_phase != null)
     starting_phase.raise_objection(this);
endtask : pre_start

task body();

  stimuli =  rra_item#(REQ_WD)::type_id::create("stimuli");
  for(int i=0; i< 20; i++) begin
    //`uvm_do(req); w
    `uvm_do(stimuli);
  end

endtask : body

task post_start();
ifdef UVM_POST_VERSION_1_1 uvm_phase starting_phase = get_starting_phase(); endif
if(starting_phase != null)
starting_phase.drop_objection(this);
endtask : post_start

endclass : multi_req_seq

class multi_req_test_65 extends rra_test_65;
`uvm_component_utils(multi_req_test_65)
multi_req_seq#(65) seq;

//–new constructor
function new(string name, uvm_component parent);
super.new(name,parent);
endfunction : new

function void build_phase(uvm_phase phase);
seq = multi_req_seq#(65)::type_id::create(“seq”);
endfunction : build_phase

task run_phase(uvm_phase phase);

   `ifdef UVM_POST_VERSION_1_1
       seq.set_starting_phase(phase);
   `else
       seq.starting_phase = phase;
   `endif    

   seq.p_sequencer = o_rra_env.o_rra_agent.o_rra_sequencer;
   seq.start(o_rra_env.o_rra_agent.o_rra_sequencer);    
   #10us;

endtask : run_phase
endclass : multi_req_test_65

Error:

** Error: (vsim-7065) /stec/proj/asic/cwm3/verification/users/mahi/rra_uvc/test_32.sv(81): Illegal assignment to class work.rra_pkg::multi_req_seq #(65) from class work.rra_pkg::multi_req_seq #(16)

Can you please help me get rid of this error?

Thanks

In reply to dmahendran:

the error occurs at this line
seq = multi_req_seq#(65)::type_id::create(“seq”);

In reply to dmahendran:

When you register multi_req_seq to the factory you need to include the parameterization as well.

`uvm_object_param_utils(multi_req_seq)

should be

`uvm_object_param_utils(multi_req_seq #(REQ_WD))
