Certainly! Below is a complete Verilog code for implementing the VGA interface and the wrapper module based on the BASYS 3 board. This code includes the necessary components to control the VGA display and test the functionality.
### VGA Interface Module (`vga_interface.v`)
```verilog
module vga_interface (
input wire CLK,
input wire [11:0] COLOUR_IN,
output reg [11:0] COLOUR_OUT,
output reg HS,
output reg VS,
output reg [9:0] X,
output reg [9:0] Y
);
// Parameters for timing
parameter H_FRONT_PORCH = 16;
parameter H_SYNC_WIDTH = 96;
parameter H_BACK_PORCH = 48;
parameter H_DISPLAY = 640;
parameter V_FRONT_PORCH = 10;
parameter V_SYNC_WIDTH = 2;
parameter V_BACK_PORCH = 33;
parameter V_DISPLAY = 480;
// Internal counters
reg [9:0] h_count;
reg [9:0] v_count;
// Synchronization signals
always @(posedge CLK) begin
if (h_count == 799) begin
h_count <= 0;
if (v_count == 520) begin
v_count <= 0;
end else begin
v_count <= v_count + 1;
end
end else begin
h_count <= h_count + 1;
end
end
// Horizontal Sync
assign HS = (h_count >= H_FRONT_PORCH && h_count < (H_FRONT_PORCH + H_SYNC_WIDTH)) ? 1'b0 : 1'b1;
// Vertical Sync
assign VS = (v_count >= V_FRONT_PORCH && v_count < (V_FRONT_PORCH + V_SYNC_WIDTH)) ? 1'b0 : 1'b1;
// Pixel coordinates
assign X = (h_count < H_FRONT_PORCH + H_SYNC_WIDTH + H_BACK_PORCH) ? 10'd0 : (h_count - (H_FRONT_PORCH + H_SYNC_WIDTH + H_BACK_PORCH));
assign Y = (v_count < V_FRONT_PORCH + V_SYNC_WIDTH + V_BACK_PORCH) ? 10'd0 : (v_count - (V_FRONT_PORCH + V_SYNC_WIDTH + V_BACK_PORCH));
// Valid signal
wire valid = (X < H_DISPLAY) && (Y < V_DISPLAY);
// Color output
always @(posedge CLK) begin
if (valid) begin
COLOUR_OUT <= COLOUR_IN;
end else begin
COLOUR_OUT <= 12'd0;
end
end
endmodule
```
### Wrapper Module (`vga_wrapper.v`)
```verilog
module vga_wrapper (
input wire CLK,
input wire [11:0] SW, // Slide switches
output wire [11:0] COLOUR_OUT,
output wire HS,
output wire VS,
output wire [9:0] X,
output wire [9:0] Y
);
// Internal signals
reg [11:0] colour_in;
// Instantiate the VGA interface
vga_interface vga_inst (
.CLK(CLK),
.COLOUR_IN(colour_in),
.COLOUR_OUT(COLOUR_OUT),
.HS(HS),
.VS(VS),
.X(X),
.Y(Y)
);
// Determine the color based on the position
always @(*) begin
colour_in = SW; // Default color from slide switches
if ((X >= 0 && X < 10) && (Y >= 0 && Y < 10)) begin
colour_in = ~SW; // Invert color in top-left corner
end else if ((X >= 630 && X < 640) && (Y >= 0 && Y < 10)) begin
colour_in = ~SW; // Invert color in top-right corner
end else if ((X >= 0 && X < 10) && (Y >= 470 && Y < 480)) begin
colour_in = ~SW; // Invert color in bottom-left corner
end else if ((X >= 630 && X < 640) && (Y >= 470 && Y < 480)) begin
colour_in = ~SW; // Invert color in bottom-right corner
end
end
endmodule
```

### Steps to Implement and Test
1. **Create Project**: Open Vivado and create a new project.
2. **Add Source Files**: Add `vga_interface.v`, `vga_wrapper.v`, and `vga.xdc` to your project.
3. **Set Top Module**: Set `vga_wrapper` as the top module.
4. **Run Synthesis and Implementation**: Run synthesis and implementation.
5. **Generate Bitstream**: Generate the bitstream file.
6. **Program FPGA**: Program the FPGA using the generated `.bit` file.
7. **Connect Monitor**: Connect the BASYS 3 board to your monitor using the VGA cable and select the appropriate input source on the monitor.
8. **Test**: Change the configuration of the slide switches to see how they affect the colors on the display.
Feel free to modify the code to add additional features or improve performance as needed.
