verilog code :

9. What does the following Verilog program do (10 points)? module unknown (x, data, clk, reset); parameter data_width = 4; parameter x_width = 3; output [x_width -1:0] x; input [data_width - 1:0) data; input clk, reset; reg [x_width-1:0) y, x; reg [data_width-1:0) temp; integer [x_width-1:0) index; always@(posedge clk) if (reset) begin y = 0; x=0; else begin y = 0; x = 0; temp = data; for (index=0; index >1; end x = y; end endmodule
