1. Select the project_name.pbd tab in the workspace to display the system block
diagram.
2. Select
Add o Component or click the Add Component toolbar button.
3. In the
Components tab, use the Categories and Components lists to specify the
component you are adding.
The component you select is attached to the mouse cursor.
Note: To make the component selection easier, type the first letter or letters of the component
in the Component Name Filter field. The Components list box shows only the components that
begin with those letters. A regular expression can also be used to filter components. For eg.
typing “.*uart” will list all components with “uart” in the name. A “.” stands for a character and “*”
means “zero or more”.
4. Click where you want the component instance to appear in the workspace.
Component instance notes:
x The PBD Editor assigns the new component instance the default name
corename_number. The number is incremented each time another instance is added.
x To rename a component instance, see “Naming an Instance”.
x If a bus pin on the component symbol touches a bus, and if the pin is compatible with
the bus type, the symbol pin is connected to the bus when the component instance is
placed in the block diagram.
Naming an Instance
When you add a component to the system, the PBD Editor assigns the new component
instance the default name corename_number, and the number is incremented each time
another instance is added. You can leave the machine-generated names as is. However, it is
usually easier to debug the design using your own names.
To rename an instance.
1. Double-click the instance in the workspace.
2. In the Object Properties dialog box, change the
Instance Name.
Setting Component Instance Parameters
You set parameters to customize the instantiated IP for your design. Parameters may be set
for CPUs, bus components, or peripherals. The properties you set depend on the type of
component and the IP (core) from which the component was instantiated.
IP parameters are described in the data sheets for the cores instantiated in the design. Data
sheets can be accessed from the Xilinx IP Center page at http://www.xilinx.com/ipcenter
.
To set parameters for a customizable component instance:
1. Double-click the component instance in the workspace.
2. In the Properties dialog box, click the
Parameters entry in the tree view on the left side
of the dialog box.
3. To override a value displayed in the
Default Parameter Values table:
a. Select the parameterin the
Default Parameter Values table.
