Table of Contents
The two-dimensional array is an array of arrays. The 2D array is organized as matrices which can be represented as the collection of rows and columns.
SystemVerilog 2D array Syntax
data_type array_name [rows][columns];
SystemVerilog 2D array declaration
int array [2:0][3:0];
The data in a two-dimensional array is stored in a tabular form as shown in the below diagram.
SystemVerilog 2D array initialization
array = '{ '{0,1,2,3},'{4,5,6,7},'{8,9,10,11}};
SystemVerilog 2D array example
module two_d_array;
//declaration of array’s
int array[2:0][3:0]; //2 dimension array
initial begin
//array initialization
array = '{'{0,1,2,3},'{4,5,6,7},'{8,9,10,11}};
//displaying array elements
$display("-------displaying 2d array-------");
foreach(array[i,j]) $display("\t array[%0d][%0d] = %0d",i,j,array[i][j]);
end
endmodule
