Refer to Chapter 9, GNU Compiler Tools,, Chapter 11, GNU Debugger, and Appendix A, GNU Utilities for more information about GNU compiler tools and utilities. Xilinx Microprocessor Debugger GNU Debugger You can debug your program in software using an Instruction Set Simulator (ISS), or on a board that has a Xilinx FPGA loaded with your hardware bitstream. As shown in Figure 1-2, page 10, the Xilinx Microprocessor Debugger (XMD) utility reads the application executable ELF file. For debugging on a physical FPGA, XMD communicates over the same download cable as used to configure the FPGA with a bitstream. Refer to Chapter 10, Xilinx Microprocessor Debugger (XMD), for more information. The GNU Debugger (GDB) is a powerful yet flexible tool that provides a unified interface for debugging and verifying MicroBlaze and PowerPC processor systems during various development phases. GDB uses Xilinx Microprocessor Debugger (XMD) as the underlying engine to communicate to processor targets. Refer to Chapter 11, GNU Debugger, for more information. Simulation Library Compiler (Compxlib) The Compxlib utility compiles the EDK HDL-based simulation libraries using the tools provided by various simulator vendors. The Compxlib operates in both the GUI and batch modes. In the GUI mode, it allows you to compile the Xilinx libraries (in your ISE installation) using the libraries available in EDK. For more information about Compxlib, see Simulation Models in Chapter 7 and the ISE Command Line Tools User Guide. For instructions on compiling simulation libraries, refer to the Xilinx Platform Studio Help Embedded System Tools Reference Manual This utility reads hardware-only bitstream produced by the ISE tools (system.bit), and outputs a new bitstream (download.bit) which includes the embedded application executable (ELF) for each processor. The utility uses the BMM file, originally generated by Platgen and updated by the ISE tools with physical placement information on each block RAM in the FPGA. Internally, the Bitstream Initializer tool uses the Data2MEM utility to update the bitstream file. See Figure 1-2, page 10, to see how the Bitinit tool fits into the overall system architecture. Refer to Chapter 12, Bitstream Initializer (BitInit), for more information. System ACE File Generator (GenACE) XPS generates Xilinx System ACE configuration files from an FPGA bitstream, ELF, and data files. The generated ACE file can be used to configure the FPGA, initialize block RAM, initialize external memory with valid program or data, and bootup the processor in a production system. EDK provides a Tool Command Language (Tcl) script, genace.tcl, that uses XMD commands to generate ACE files. ACE files can be generated for PowerPC processors and MicroBlaze processors with Microprocessor Debug Module (MDM) systems. For more information see Chapter 13, System ACE File Generator (GenACE). Flash Memory Programmer The Flash Memory Programming solution is designed to be generic and targets a wide variety of flash hardware and layouts. See Chapter 14, Flash Memory Programming. Format Revision Tool and Version Management Wizard The Format Revision Tool (revup) updates an existing EDK project to the current version. The revup tool performs format changes only; it does not update your design. Backups of existing files such as the project file (XMP), the MHS and MSS files, are performed before the format changes are applied. The Version Management wizard appears automatically when an older project is opened in a newer version of EDK (for example, when a project created in EDK 10.1 is opened in version 11.3). The Version Management wizard is invoked after format revision has been performed. The wizard provides information about any changes in Xilinx Processor IPs used in the design. If a new compatible version of an IP is available, then the wizard also prompts you to update to the new version. For instructions on using the Version Management wizard, see Chapter 15, Version Management Tools (revup), and the Xilinx Platform Studio Help. Microprocessor Peripheral Definition Translation tool (MPDX) For board designers not familiar with the IP-XACT tool, a board description can be captured in an ASCII text file similar to the Microprocessor Peripheral Definition (MPD) format that captures a pcore description. This MPD file is known as the Board-MPD. It includes a translation tool, MPDX, which generates the IP-XACT files on disk for the BSB repository. Chapter 16, Microprocessor Peripheral Definition Translation tool (MPDX) describes how to use this tool. Embedded System Tools Reference Manual 19 MPD files are required to create IP peripherals that are compliant with the Embedded Development Kit (EDK). The Create and Import Peripheral (CIP) wizard in the Xilinx Platform Studio (XPS) interface supports features provided by the PsfUtility for MPD file creation (recommended). Tool Options Table 2-1 lists the PsfUtility Syntax options and their descriptions. Suboptions are: -lp Add one or more additional IP library search paths -o Specify output filename; default is stdout Help -h, -help Displays the usage menu and then exits. To create a peripheral and deliver it through EDK: 1. Code the IP in VHDL or Verilog using the required naming conventions for Bus, Clock, Reset, and Interrupt signals. These naming conventions are described in detail in Conventions for Defining HDL Peripherals on page 25. Note: Following these naming conventions enables the PsfUtility to create a correct and complete MPD file. 2. Create an XST (Xilinx Synthesis Technology) project file or a PAO file that lists the HDL sources required to implement the IP. 3. Invoke the PsfUtility by providing the XST project file or the PAO file with additional options. For more information on invoking the PsfUtility with different options, see the following section, Use Models for Automatic MPD Creation, page Embedded System Tools Reference Manual 23 Use Models for Automatic MPD Creation Use Models for Automatic MPD Creation You can run the PsfUtility in a variety of ways, depending on the bus standard and bus interface types used with the peripheral and the number of bus interfaces a peripheral contains. Bus standards and types can be one of the following: AXI4 MASTER AXI4 SLAVE AXI4LITE MASTER AXI4LITE SLAVE AXI STREAMING (same as POINT TO POINT) DCR (design control register) SLAVE FSL (fast simplex link) SLAVE FSL MASTER LMB (local memory bus) SLAVE PLBV46 (processor local bus version 4.6) SLAVE PLBV46 MASTER POINT TO POINT BUS (special case) Peripherals with a Single Bus Interface Most processor peripherals have a single bus interface. This is the simplest model for the PsfUtility. For most such peripherals, complete MPD specifications can be obtained without any additional attributes added to the source code. Signal Naming Conventions The signal names must follow the conventions specified in Conventions for Defining HDL Peripherals on page 25. When there is only one bus interface, no bus identifier need be specified for the bus signals. These interfaces can be exclusive bus interfaces, non-exclusive bus interfaces, or a combination of both. All bus interfaces on the peripheral that can be connected to the peripheral simultaneously are exclusive interfaces. For example, an OPB Slave bus interface and a DCR Slave bus interface are exclusive because they can be connected simultaneously. On a peripheral containing exclusive bus interfaces: a port can be connected to only one of the exclusive bus interfaces. Non-exclusive bus interfaces cannot be connected simultaneously. Peripherals with non-exclusive bus interfaces have ports that can be connected to multiple non-exclusive interfaces.
