- To control the values that are getting assigned to the random variable on randomization we need to define constraints.
- Constraint provides control on randomization.
class packet;
rand bit [3:0] addr;
constraint addr_range { addr > 5; }
endclass
module constr_blocks;
initial begin
packet pkt;
pkt = new();
repeat(10) begin
pkt.randomize();
$display("\taddr = %0d",pkt.addr);
end
end
endmodule
