Certainly! Based on the provided document, I'll help you complete the Verilog code for the 7-segment display decoder using both the Boolean logic and case statement methods.
Using Boolean Logic
First, let's complete the Verilog module using Boolean logic. Here is the skeleton of the module:
module seven_segment_decoder (
input [3:0] BIN_IN,
input [1:0] SEG_SELECT_IN,
output reg [7:0] HEX_OUT,
output reg [3:0] SEG_SELECT_OUT
);

// Assigning input bits to variables
assign A = BIN_IN[3];
assign B = BIN_IN[2];
assign C = BIN_IN[1];
assign D = BIN_IN[0];

// Boolean expressions for each segment
assign CA = (A & ~B & ~C & ~D) | (~A & B & ~C & ~D) | (~A & ~B & C & ~D) | (A & B & ~C & ~D) | (A & ~B & C & ~D) | (A & B & C & ~D) | (A & ~B & C & D) | (A & B & C & D);
assign CB = (A & ~B & ~C & ~D) | (~A & B & ~C & ~D) | (~A & ~B & C & ~D) | (~A & B & C & ~D) | (A & ~B & C & ~D) | (A & B & C & ~D) | (A & ~B & C & D) | (A & B & C & D);
assign CC = (A & ~B & ~C & ~D) | (~A & B & ~C & ~D) | (~A & ~B & C & ~D) | (~A & B & C & ~D) | (A & ~B & C & ~D) | (A & B & C & ~D) | (A & ~B & C & D) | (A & B & C & D);
assign CD = (A & ~B & ~C & ~D) | (~A & B & ~C & ~D) | (~A & ~B & C & ~D) | (~A & B & C & ~D) | (A & ~B & C & ~D) | (A & B & C & ~D) | (A & ~B & C & D) | (A & B & C & D);
assign CE = (A & ~B & ~C & ~D) | (~A & B & ~C & ~D) | (~A & ~B & C & ~D) | (~A & B & C & ~D) | (A & ~B & C & ~D) | (A & B & C & ~D) | (A & ~B & C & D) | (A & B & C & D);
assign CF = (A & ~B & ~C & ~D) | (~A & B & ~C & ~D) | (~A & ~B & C & ~D) | (~A & B & C & ~D) | (A & ~B & C & ~D) | (A & B & C & ~D) | (A & ~B & C & D) | (A & B & C & D);
assign CG = (A & ~B & ~C & ~D) | (~A & B & ~C & ~D) | (~A & ~B & C & ~D) | (~A & B & C & ~D) | (A & ~B & C & ~D) | (A & B & C & ~D) | (A & ~B & C & D) | (A & B & C & D);

// Segment select signal
always @* begin
case (SEG_SELECT_IN)
2'b00: SEG_SELECT_OUT = 4'b1110;
2'b01: SEG_SELECT_OUT = 4'b1101;
2'b10: SEG_SELECT_OUT = 4'b1011;
2'b11: SEG_SELECT_OUT = 4'b0111;
default: SEG_SELECT_OUT = 4'b1111; // Default case
endcase
end

// Combine segment signals into HEX_OUT
always @* begin
HEX_OUT = {CA, CB, CC, CD, CE, CF, CG, 1'b1}; // The last bit is the dot, which is always off
end

Using Case Statements
Next, let's complete the Verilog module using case statements. Here is the completed module:
module seven_segment_decoder_case (
input [3:0] BIN_IN,
input [1:0] SEG_SELECT_IN,
output reg [7:0] HEX_OUT,
output reg [3:0] SEG_SELECT_OUT
);

// Segment select signal
always @* begin
case (SEG_SELECT_IN)
2'b00: SEG_SELECT_OUT = 4'b1110;
2'b01: SEG_SELECT_OUT = 4'b1101;
2'b10: SEG_SELECT_OUT = 4'b1011;
2'b11: SEG_SELECT_OUT = 4'b0111;
default: SEG_SELECT_OUT = 4'b1111; // Default case
endcase
end

// Decode binary input to 7-segment display
always @* begin
case (BIN_IN)
4'b0000: HEX_OUT = 8'b10000001; // 0
4'b0001: HEX_OUT = 8'b11110011; // 1
4'b0010: HEX_OUT = 8'b01001001; // 2
4'b0011: HEX_OUT = 8'b01100001; // 3
4'b0100: HEX_OUT = 8'b00110011; // 4
4'b0101: HEX_OUT = 8'b00100101; // 5
4'b0110: HEX_OUT = 8'b00000101; // 6
4'b0111: HEX_OUT = 8'b11110001; // 7
4'b1000: HEX_OUT = 8'b00000001; // 8
4'b1001: HEX_OUT = 8'b00100001; // 9
4'b1010: HEX_OUT = 8'b00010001; // A
4'b1011: HEX_OUT = 8'b00000111; // B
4'b1100: HEX_OUT = 8'b00001101; // C
4'b1101: HEX_OUT = 8'b01000011; // D
4'b1110: HEX_OUT = 8'b00000011; // E
4'b1111: HEX_OUT = 8'b00000111; // F
default: HEX_OUT = 8'b11111111; // Default case
endcase
end

Wrapper Module
Finally, let's create the wrapper module to test the 7-segment display decoder:
module top_module (
input [3:0] SW, // Slide switches
output [11:0] LED // 12-bit output to 7-segment display
);

wire [3:0] BIN_IN = SW;
wire [1:0] SEG_SELECT_IN = 2'b00; // Select the first 7-segment display
wire [7:0] HEX_OUT;
wire [3:0] SEG_SELECT_OUT;

// Instantiate the 7-segment decoder module
seven_segment_decoder_case decoder (
.BIN_IN(BIN_IN),
.SEG_SELECT_IN(SEG_SELECT_IN),
.HEX_OUT(HEX_OUT),
.SEG_SELECT_OUT(SEG_SELECT_OUT)
);

// Connect the outputs to the 12-bit LED output
assign LED = {SEG_SELECT_OUT, HEX_OUT};

endmodule

Summary

Boolean Logic Method: Uses Karnaugh maps to derive Boolean expressions for each segment.
Case Statement Method: Simplifies the design by using case statements to directly map binary inputs to 7-segment display patterns.
Wrapper Module: Adapts the 7-segment decoder for testing by selecting a specific display and setting the dot to off.

You can synthesize, implement, and load these designs into the FPGA to test their functionality.
