Boolean OR Gate

Description

This component is a logic OR gate. The output is true if one or more inputs are true. The output is false if all inputs are false.

Features

  • User definable input count (2-26 inputs).

  • All inputs and the output are freely negatable.

  • The component supports a user definable reset state. The output adopts this state during the reset cycle and keeps this state until the first simulation cycle is finished. The default reset state is false.

  • The component is rotatable.

  • Use the component popup menu to add a new or remove a input (Currently you can only remove the last input which has to be unconnected).

Boolean XOR Gate

Description

This component is a logic XOR gate. The output is true if count of inputs with true level is odd. In other case the output is false.

Features

  • User definable input count (2-26 inputs).

  • All inputs and the output are freely negatable.

  • The component supports a user definable reset state. The output adopts this state during the reset cycle and keeps this state until the first simulation cycle is finished. The default reset state is false.

  • The component is rotatable.

  • Use the component popup menu to add a new or remove a input (Currently you can only remove the last input which has to be unconnected).

Boolean XNOR Gate

Description

This component is a logic XNOR gate. The output is true if count of inputs with true level is even (or zero). In other case the output is false.

Features

  • User definable input count (2-26 inputs).

  • All inputs and the output are freely negatable.

  • The component supports a user definable reset state. The output adopts this state during the reset cycle and keeps this state until the first simulation cycle is finished. The default reset state is false.

  • The component is rotatable.

  • Use the component popup menu to add a new or remove a input (Currently you can only remove the last input which has to be unconnected).
