Bus Layout

As layouts become more complex, you may wish to group inputs and outputs logically into buses. A bus is simply a named collection of inputs or of outputs. Once your design contains inputs and/or outputs, you can group them into buses using the bus layout dialog. You can invoke this dialog by choosing "Main Menu:Tools→Bus Layout...", or by clicking Bus on the layers toolbar.

Bus layout dialog

To create, for example, an input bus, select several inputs listed on the left, and click "Create Bus". You can hold down Ctrl or Shift to select multiple inputs.

Using the buttons on the right, you can raise the significance of cells within a bus, and you can modify the order the buses are stored in. This is the order the simulation results will be displayed in. Inputs and outputs not grouped into buses remain at the end of the list.
