Verilog---Vectors

1.Vectors

module top_module(
	input [2:0] vec, 
	output [2:0] outv,
	output o2,
	output o1,
	output o0
);
	
	assign outv = vec;

	// This is ok too: assign {o2, o1, o0} = vec;
	assign o0 = vec[0];
	assign o1 = vec[1];
	assign o2 = vec[2];
	
endmodule

2.Vectors in more detail

module top_module( 
    input wire [15:0] in,
    output wire [7:0] out_hi,
    output wire [7:0] out_lo );
    
    assign out_hi = in[15:8];
    assign out_lo = in[7:0];

endmodule

3.Vector part select

module top_module( 
    input [31:0] in,
    output [31:0] out );//

    // assign out[31:24] = ...;
    assign out[31:24] = in[7:0];
    assign out[23:16] = in[15:8];
    assign out[15:8] = in[23:16];
    assign out[7:0] = in[31:24];

endmodule

4.Bitwise oparators

module top_module( 
    input [2:0] a,
    input [2:0]
