Controlled Buffer/Inverter

Library: Gates
Introduced: 2.0 Beta 1

Behavior

The controlled buffer and inverter, often called three-state buffers/inverters, each have a one-bit "control" input pin on the south side. The value at this control pin affects how the component behaves:

Controlled buffers can be useful when you have a wire (often called a bus) whose value should match the output of one of several components. By placing a controlled buffer between each component output and the bus, you can control whether that component's output is fed onto the bus or not.

Pins

West edge (input, bit width matches Bit Width attribute)
The component input that will be used to compute the output if the control input is 1.
South edge (input, bit width 1)
The component's control input.
East edge (output, bit width matches Bit Width attribute)
The component's output, which will be floating if the control input is 0 or floating, the error value if the control input is the error value, and will be computed based on the west-side input if the control input is 1.

Attributes

Bit Width
The bit width of the component's inputs and outputs.

Poke Tool Behavior

None.

Text Tool Behavior
