Working with Microprocessor and Peripheral IP

Xilinx® Platform Studio (XPS), available in the Embedded Development Kit (EDK), allows you to create an embedded processor system. XPS saves your embedded processor system in a Xilinx microprocessor project (XMP) file that you can add as a module to your ISE® project.

Following are the basic steps for developing an embedded processor system, which are described in detail below:

Create an ISE project.
Add embedded processor source (XMP file) to the ISE project, or create the embedded processor system in XPS.
Instantiate the XMP module in the top-level HDL file.
Edit the embedded processor system.
Associate ELF files with embedded processors in the ISE design.
Optionally, simulate the embedded processor system.
Implement the ISE design.
View implementation results data.
Generate a BIT file with the hardware and embedded software data.
Export the hardware design to SDK.

Note EDK is included in the ISE Design Suite: Embedded Edition and System Edition. If you are using a different Edition, you can order EDK separately. For documentation and information on ordering EDK, see the Platform Studio and the EDK Web page. To access the XPS Help, selectHelp > Help Topics in the XPS software.

To Create an ISE Project

To create an ISE project, see Creating a Project.

Note You must select HDL or Schematic as your Top-Level Source Type.

To Add an Embedded Processor System to an ISE Project

When you create the embedded processor system for your design in the ISE software, XPS creates an embedded processor project file with a .xmp extension. If you generated your source file using the New Source Wizard and selected Add to Project, you do not need to add the XMP file to your project; it is automatically added to your project and appears in the Hierarchy pane of the Design panel.

Note If you did not automatically add the XMP file to your ISE project, you can add the XMP file to your ISE project, as described in Adding a Source File to a Project. XMP source files mustremain in their original directories. Therefore, you must use the Add Source command rather than Add Copy of Source command when adding XMP files.

To Create an Embedded Processor System

You can create an embedded processor module in the Project Navigator New Source Wizard as follows:

Create your embedded submodule as described inCreating a Source File, selecting Embedded Processor as your source type. After you click Finish, Project Navigator opens XPS. Note Embedded Development Kit (EDK) must be installed on your system to enableEmbedded Processor as a source type option. For instructions on configuring XPS on Linux operating systems, see the ISE Design Suite: Release Notes Guide (UG631)available from the Xilinx® website.
In XPS, create the embedded processor system for your design, as described in Procedures for Embedded Processor Design > Using ISE Project Navigator to Implement Your FPGA Design > Creating an XPS Design as an ISE Submodule in the XPS Help.

Note To include the embedded processor module in the ISE project, the device settings for the embedded processor module must match the device settings of the ISE project. When you use the New Source Wizard to create your embedded processor module, the module automatically inherits the device settings of the ISE project. If you create the module outside of Project Navigator, directly in XPS, you must manually ensure that the device settings match. If Project Navigator detects a device mismatch when the embedded processor module is added to the ISE project, an error is issued and you are given the option to allow Project Navigator to automatically update the target device in the embedded processor module to match the target device in the ISE project.

To Instantiate the Embedded Processor System into the ISE Design

It is recommended that you instantiate XMP source files as lower-level modules in an ISE design as follows:

In the Hierarchy pane of the Design panel, select the XMP file.
Do one of the following:

Run theView HDL Instantiation Templateprocess. Add the code from the template to your top-level design source file, as described inAdding Code Using Language Templates.
Run theGenerate Top HDL Sourceto create a new HDL file that acts as the top-level source file for your XPS project.

Note An XMP source cannot be the top-level source file in an ISE project. Until the XMP source is properly instantiated in another design module, implementation processes are not available in the ISE software. When the XMP source is properly instantiated in another design module, it appears underneath that module in the Hierarchy pane of the Design panel.

To Edit the Embedded Processor System

After you add the XMP file to the ISE project, you can double-click the XMP file in the Hierarchy pane of the Design panel to edit it directly in XPS. If the top-level ports are modified in the XPS project, you must make the necessary changes to the embedded instantiation code.

Note Alternatively, you can edit the XMP file as described in Managing the Processor Design (XPS)

To Associate ELF Files with Embedded Processors in the ISE Design

In Project Navigator, ELF files that are associated with the processors in XPS automatically appear under the XMP file in the Hierarchy pane of the Design panel. You can add the ELF files to the project and associate them with individual processors in the XMP source file as follows:

Select Project > Add Source.
In the Add Source dialog box, select the ELF file, and click Open.
In the Adding Source dialog box, specify the Design View Association, whether Implementation, Simulation, or All, and click OK. For more information, see Using the Design Views.
In theELF/XMP File Associations dialog box, select the processor instance to associate with the ELF file, and click OK.
（要说明的一点是：elf文件在你的xps文件中的empty_application_0\debuge中）。

Note After the ELF files are added to the project, you can view or modify file associations from the Hierarchy pane. Right-click an ELF file, and select Elf/Xmp File Associations to open the ELF/XMP File Associations dialog box. Alternatively, right-click an XMP file, and select Xmp/Elf File Associations to open the XMP/ELF File Associations dialog box.

To Simulate the Embedded Processor System

If the XMP source files are instantiated as lower-level modules in your ISE design, you can simulate the design normally, as described in the Simulation Overview, and the Project Navigator and EDK software automatically generate the simulation files necessary for simulating your embedded processor system.

You can use the Generate HDL Test Bench (XPS) process to create a template test bench for the XMP embedded processor module. You can then do either of the following:

Use this test bench directly to simulate the embedded processor module.
Copy the test bench contents into a higher level design test bench, and modify the paths to simulate the embedded processor module as part of the larger design.

Note The XMP module cannot be simulated directly. It must be instantiated directly in a test bench or instantiated as part of a larger design.

To Implement the Embedded Processor System

After you instantiate the XMP source files as lower-level modules in your ISE design, you can implement your design as described in Implementation Overview for FPGAs. After implementation, the embedded processor system is included in the placed and routed design.

Following are additional details regarding implementation behavior:

Synthesis and implementation options are not shared between XPS and Project Navigator. Note When setting Map Properties in Project Navigator, Xilinx recommends that you set the Map Effort Level to High when working with an embedded processor system.
Process status becomes out-of date in the Processes pane of the Design panel if you modify your embedded processor system in XPS. For example, changes to the MHS file cause the Synthesis and Implement Design processes to become out-of-date. Changes to the User Constraints File (UCF) cause the Implement Design process to become out-of-date. For more information on process status, seeRunning and Stopping Processes.
Constraints generated in XPS (for the system module as well as instantiated embedded IP) are automatically copied into the ISE project directory as NCF files and are picked up automatically when you implement your design. If you need to modify the constraints associated with the embedded processor system, you must modify the constraints in XPS.

Note For more information, see Copying Constraints to Your ISE Project in the XPS Help.

To View Implementation Results Data

The Project Navigator Design Summary provides access to ISE synthesis and implementation reports and messages as well as XPS reports and messages from the PlatGen, LibGen, SimGen and BitInit programs. For more information, see the Design Summary Overview.

To Generate a Bitstream File with Processor Data

To generate a bitstream file with processor data, run the Generate Programming File process. This process generates the bitstream for the hardware components of the FPGA device, including the software application data from the ELF files that are part of the project.

To Export the Hardware Design to SDK

For embedded software development, the XPS hardware description must be exported to the Software Development Kit (SDK). You can export just the hardware description file without the bitstream and BMM files, or you can export the hardware description file with the bitstream and BMM files. For more information, see Exporting a Hardware Design to SDK.
