A bus is a collection of
signals concatenated in a
specific order to create a
new virtual signal with a
specific value.
In the illustration below, four data signals have been combined to form a new bus
called DATA1. Notice, the new bus has a value that is made up of the values of
its component signals arranged in a specific order. Virtual objects are indicated by
an orange diamond.
