![### Question:
How many levels of logic are there between DataIn and DataOut?
### Code Explanation:
The Verilog module `BitReverser` is designed to reverse the order of bits from the input `DataIn` to the output `DataOut`. It takes the clock (`Clk`) and reset (`Rst`) signals as inputs, along with an 8-bit input vector `DataIn` and generates an 8-bit output vector `DataOut`.
#### Code:
```verilog
module BitReverser (
input logic Clk,
input logic Rst,
input logic [7:0] DataIn,
output logic [7:0] DataOut
);
assign DataOut[7] = DataIn[0];
assign DataOut[6] = DataIn[1];
assign DataOut[5] = DataIn[2];
assign DataOut[4] = DataIn[3];
assign DataOut[3] = DataIn[4];
assign DataOut[2] = DataIn[5];
assign DataOut[1] = DataIn[6];
assign DataOut[0] = DataIn[7];
endmodule
```
### Logic Level Explanation:
In this module, each bit of `DataOut` is directly assigned to a specific bit of `DataIn`. There are no intermediate logic operations between `DataIn` and `DataOut`. This constitutes a single level of logic.
### Options for the Answer:
- [ ] 0
- [X] 1
- [ ] 4
- [ ] 8
The correct answer is **1** because there is only one direct assignment operation for each bit from `DataIn` to `DataOut`.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6d1ae07f-bdb5-47a8-9afa-ea5a04bdf9c8%2Fc343cf2a-308c-4fc9-849e-34841c260a0d%2Fkj0qm4o_processed.jpeg&w=3840&q=75)
