**Title: Understanding Encoding Techniques in Digital Logic Design**

**Introduction:**

In this educational snippet, we'll examine a digital logic module called `FrameChecker`, and discuss which encoding technique minimizes logic on the 'ErrorOut' signal.

**Verilog Code Explanation:**

```verilog
module FrameChecker(
input logic Clk,
input logic Rst,
input logic StartIn,
input logic EndIn,
output logic ErrorOut
);

typedef enum { sReset, sIdle, iActive } StateType;
StateType sState;

always @(posedge Clk or posedge Rst) begin
if ( Rst ) begin
ErrorOut <= 0;
sState <= sReset;
end else begin
ErrorOut <= 0;
case ( sState )
sReset: begin
sState <= sIdle;
end
sIdle : begin
if ( StartIn ) begin
sState <= iActive;
end
end
iActive : begin
if ( EndIn ) begin
sState <= sIdle;
end
if ( StartIn ) begin
ErrorOut <= 1;
end
end
endcase
end
end
endmodule
```

**Code Explanation:**

The `FrameChecker` module involves:

- **Inputs:** Clk (Clock), Rst (Reset), StartIn, EndIn
- **Output:** ErrorOut

**State Definition:**

- The `StateType` enumeration includes three states: `sReset`, `sIdle`, and `iActive`.

**Behavior:**

- The `always` block triggers on a positive edge of the clock or reset signal.
- If reset (`Rst`) is high, `ErrorOut` is set to 0 and `sState` becomes `sReset`.
- Under normal conditions (not reset):
- `ErrorOut` defaults to 0.
- The state machine transitions between `sReset`, `sIdle`, and `iActive` based on `StartIn` and `EndIn` signals.
- If `StartIn` is received in the `iActive` state before an `EndIn`, `ErrorOut` is set to 1, indicating an error.

Expert Solution

Introduction

It boils down to such an optimization issue that relies on a wide range of variables since encoding has advantages and disadvantages. The original encoding is indeed the best option if a very simple system produces outcomes that are very comparable across encodings. Gray code is a particularly suitable option if the FSM cycles throughout its states in a single route, much like a counter.
