I have declared a queue in which at every posedge ,I push_back values from input ports as declared below. But i see unknown values for first two. What may be the issue.
if(data_in_vld && rd_wr_en==0)
row_adq.push_back(addr_in[3:0]); //issue in this statement[img][/img][url=]Your text to link here...[/url]
$display("ROW ADDRESS is %p",row_adq);
