Error in registering

[qwerty123]

I have declared a class of type byte_array,

class byte_array extends uvm_object;

byte a[];

`uvm_object_utils_begin(byte_array)

`uvm_field_array_int(a,UVM_ALL_ON)

`uvm_object_utils_end

function new(int size);

a = new;

endfunction

endclass

In the sequence item class i have defined a variable of that type(byte_array).

I have registered it with uvm_field object. But its giving an error.

Whats the right way to do that?

class abc extends uvm_sequence_item;

byte_array payload;

`uvm_object_utils_begin(abc)

`uvm_field_object(payload,UVM_ALL_ON)

`uvm_object_utils_end

endclass

Check the class reference manual : the prototype of new for a uvm_object is function new (string name = "")

[qwerty123]

class byte_array extends uvm_object;

byte a[];

`uvm_object_utils_begin(byte_array)

`uvm_field_array_int(a,UVM_ALL_ON)

`uvm_object_utils_end

function new(string name = " byte_array" ,int size);

a = new;

super.new(name);

endfunction

endclass

class abc extends uvm_sequence_item;

byte_array payload;

`uvm_object_utils_begin(abc)

`uvm_field_object(payload,UVM_ALL_ON)

`uvm_object_utils_end

endclass

I did the following changes, Its giving the following errors:-

copy is not a class item.

clone is not a class item.

The prototype of the new() function should be respected. Here is a possible solution for your purpose:

class byte_array extends uvm_object;

byte a[];

`uvm_object_utils_begin(byte_array)

`uvm_field_array_int(a,UVM_ALL_ON)

`uvm_object_utils_end

function void set_byte_array_size(int size);

a = new;

endfunction

endclass

class abc extends uvm_sequence_item;

byte_array payload=new();

int payload_size;

`uvm_object_utils_begin(abc)

`uvm_field_object(payload,UVM_ALL_ON)

`uvm_object_utils_end

function void set_payload_size(int size);

payload.set_byte_array_size(size);

endfunction

endclass

Then, when using class abc :

abc myAbc=new();

initial myAbc.set_payload_size(5);
