i am having a bit stream of 128 bits @ each posedge of clk,i.e.total 10 bit streams each of length 128 bits.
i want to divide the 128 bit stream into 8, 8 bits n hve to store them in a ram / memory of width 8 bits.
i did it by assigning 8, 8 bits to wires of size 8 bit.in this way there are 16 wires.
and i am using dual port ram...wen i cal module of memory in stimulus.i don know how to give input....as i am hving 16 different wires naming from k1 to k16.
**codeeee**
// this is stimulus file
module final_stim;
reg [7:0] in,in_data;
reg clk,rst_n,rd,wr,rd_data,wr_data;
wire [7:0] out,out_wr, ouut;
wire[7:0] d;
integer i;
//wire[7:0] xor_out;
reg kld,f;
reg [127:0]key;
wire [127:0] key_expand;
wire [7:0]out_data;
reg [7:0] k;
//wire [7:0] k1,k2,k3,k4,k5,k6,k7,k8,k9,k10,k11,k12,k13,k14,k15,k16;
wire [7:0] out_data1;
**//key_expand is da output which is giving 10 streams of size 128 bits.**
assign k1=key_expand[127:120];
assign k2=key_expand[119:112];
assign k3=key_expand[111:104];
assign k4=key_expand[103:96];
assign k5=key_expand[95:88];
assign k6=key_expand[87:80];
assign k7=key_expand[79:72];
assign k8=key_expand[71:64];
assign k9=key_expand[63:56];
assign k10=key_expand[55:48];
assign k11=key_expand[47:40];
assign k12=key_expand[39:32];
assign k13=key_expand[31:24];
assign k14=key_expand[23:16];
assign k15=key_expand[15:8];
assign k16=key_expand[7:0];
**// then the module of memory is instanciated.
//here k1 is sent as input.but i don know how to save the other values of k.
//i tried to use for loop but it dint help**
