Hi,

How can I print an associative array which is of this form : The type of transaction that is stored in the array is an axiTransaction.

axiTrans wr_input_array[int][addr];

Thanks.

There are multiple ways to do it.


//1
/*
If axiTrans class is extended from the uvm_object(or any child class of it) and field macros are used then use sprint to print it.
*/
class axi_tran extends uvm_object;
  logic [31:0] data;
 
  `uvm_object_utils_begin(axi_tran)
    `uvm_field_int(data, UVM_DEFAULT)
  `uvm_object_utils_end
  
  function new(string name = "axi_tran");
    super.new(name);
  endfunction
  
  //other methods
endclass : axi_tran


/* ..... other code ......... */
/* ..... other code ......... */
/* ..... other code ......... */

//print the transaction
//display master 0, addr = 2, transaction
$display(axi_tran_arr[0][addr].sprint());
//or use uvm_info
//`uvm_info("", $sformatf("%p",axi_tran_arr[0][addr].sprint()),UVM_LOW);
    
  
///OUTPUT:
------------------------------------
Name      Type      Size  Value     
------------------------------------
axi_tran  axi_tran  -     @339      
  data    integral  32    'h4a7a3d21
------------------------------------

 


//2
//create method to print the transaction
class axi_tran;
  logic [31:0] data;
 
  //create method to print the transaction, can give any name
  function void display();
    $display("---------------------");
    $display("axi_tran");
    $display("data : %h", data);
    //.... add for other variable also
    $display("---------------------");
  endfunction
 
endclass : axi_tran

/* ..... other code ......... */
/* ..... other code ......... */
/* ..... other code ......... */

//print the transaction
//display master 0, addr = 2, transaction
    axi_tran_arr[0][2].display();
      
///OUTPUT:
---------------------
axi_tran
data : 4a7a3d21
