Parallel I/O Ports
To add a parallel IO port to the system, select Add Parallel IO Port under the Add menu. The
parallel I/O properties window will appear as in Figure A-9. From here, the user can assign the
port a reference designator (i.e. name) in the Port name text input box, the first drive line where
the port begins by using the First drive line drop menu, and the number of the drive lines that the
port contains by using the Number of drive lines text input box.

Wire Types and Wires
A wire is created to define a connection between two components in an EX7000 system. Before
creating a wire, however, a wire type must be defined. The wire type is used to describe the
physical characteristics (impedance, bandwidth) of a wire that will be used.
To do this, select Add Wire Type from the Add menu. The Add new wire type prompt will
appear. Enter a name for the wire type being created, then click the Add button to add this
component to the system. Continue to add wire types in this manner until all wire types that will
be used have been defined, then close the prompt. Once the Add new wire type prompt is closed,
the added wire types will appear in the Wire Library folder in the System Explorer. When a wire
type is selected in the Wire Library, the user can define the wire’s characteristic impedance (in
ohms) and bandwidth (in GHz) as shown in Figure A-10.
