Gates
CircuitVerse features the following gates in the circuit elements library:
Properties that can be customized in the PROPERTIES panel include: Bit Width, Input Size, Direction
TIP: Direction of any gate can be changed within the CircuitVerse simulator by either using the up, down, right, left arrow keys or by changing the Direction property parameter in the PROPERTIES panel.
Each of the gates included in the CircuitVerse library can be customized for multiple input size and multiple bitwidth. Users can create:
- Multi-input gate by changing the Input Size property parameter in the PROPERTIES panel. You can verify the behavior of a multi-input AND gate in the live circuit embedded below:
- Multi-bitwidth AND gate by changing the BitWidth property parameter in the PROPERTIES panel. You can verify the behavior of a multi-bitwidth AND gate in the live circuit embedded below:
AND Gate
AND gate gives a HIGH output only if all input values are HIGH. Refer Table 4.25.

| Input 1 | Input 2 | Output |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
You can verify the behavior of the AND gate circuit element in the live circuit of a two-input AND gate embedded below:
OR Gate
OR gate produces a HIGH output only if any of the input values are HIGH. Refer Table 4.26.

| Input 1 | Input 2 | Output |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
You can verify the behavior of an OR gate circuit element in the live circuit embedded below:
NOT Gate
NOT gate inverts the input as an output. It is also known as an inverter. Refer Table 4.27.
Table 4.27: NOT gate truth table
| Input | Output |
|---|---|
| 0 | 1 |
| 1 | 0 |
You can verify the behavior of an NOT gate circuit element in the live circuit embedded below:
XOR Gate
XOR gate produces a HIGH output only if both inputs aren't the same. Refer Table 4.28.

| Input 1 | Input 2 | Output |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
You can verify the behavior of an XOR gate circuit element in the live circuit embedded below:
NAND Gate
NAND gate, a combination of an AND gate and a NOT gate connected together in series, produces the inverted output of an AND gate––produces a LOW output when all the inputs are HIGH. Refer Table 4.29.
Table 4.29: Two-input NAND gate truth table
| Input 1 | Input 2 | Output |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
You can verify the behavior of an NAND gate circuit element in the live circuit embedded below:
NOR Gate
NOR gate inverts the output of an OR gate. In other words, it only goes HIGH when all the inputs are LOW. Refer Table 4.30.

| Input 1 | Input 2 | Output |
|---|---|---|
| 0 | 0 | 1 |

| Input 1 | Input 2 | Output |
|---|---|---|
| 0 | 0 | 1 |
