Display
Inputs
| Pin | Type | Description |
|---|---|---|
| D | bit | Input signal — the value to display (0 or 1) |
Outputs
| Pin | Type | Description |
|---|
This element has no outputs.
How It Works
The Display is a purely visual debugging tool — it shows the current signal value at any point in your circuit without affecting the circuit's behavior.
The display supports three numeric formats, toggled by double-clicking the element:
| Format | Example (value 15) |
|---|---|
| Decimal | 15 |
| Binary | 00001111 |
| Hexadecimal | 0F |
Each double-click cycles to the next format: Dec → Bin → Hex → Dec → …
Since the Display has no outputs, it cannot serve as a signal source or sink — it is purely for observation. Place it inline on any wire or connect it as a branch from any signal to monitor its value.
Usage
The Display is a universal debugging element — use it on any level to inspect intermediate signals:
- Bit monitoring: connect D to any single-bit wire (Clock, control signals, flags).
- Bus debugging: when connected to a bus line, show the value at that point.
- Signal tracing: place multiple Displays throughout your circuit to observe signal flow during simulation.
The Display is always available in the component palette and has no level restrictions. It is the simplest and most frequently used debugging tool in the simulator.
