This is window 3 of the ALU Wizard. This window contains the following items
| Control Bus | Select Yes or No. Yes means that the control consists of a single multi-bit bus. No means that the control consists of several single-bit inputs. The number of inputs, or the bus width, must match the width specified on ALU Wizard window 1. If carry enable or carry in are specified (See window 4), they will be included in the control bus. The control bus has a width of 4, 5, or 6, depending on whether carry enable and carry in are specified. |
| Control Bus Name | This box appears if the control is a bus. This box gives the name of the control bus. |
| Control List | If the control is a collection of single bit inputs, this list contains the names of each of the inputs. This list appears if Control Bus is set to No. This list includes only the first four bits of the control bus. The other two bits, if present, must be specified on window 4. |
| Replicate | This button appears if Control Bus is set to No. Clicking this button will cause the Replicate window to appear. This window can be used to create names for the control inputs, if they are named in a regular fashion. |
| Output Bus | Select Yes or No. Yes means that the output consists of a single multi-bit bus. No means that the output consists of several single-bit inputs. The number of outputs, or the bus width, must match the width specified on ALU Wizard window 1. |
| Output Bus Name | This box appears if the output is a bus. This box gives the name of the output bus. |
| Output List | If the output is a collection of single bit inputs, this list contains the names of each of the outputs. This list appears if Output Bus is set to No. |
| Replicate | This button appears if Output Bus is set to No. Clicking this button will cause the Replicate window to appear. This window can be used to create names for the outputs, if they are named in a regular fashion. |
| Finish | Create the ALU using the information provided so far, and copy it to the clipboard. |
| Cancel | Exit the wizard without making changes. |
| Next | Display ALU Wizard window number 4. |
| Back | Display ALU Wizard window number 2. |
