Embedded Systems Cheat Sheet

1. XPS TOOL FLOWS Hardware Platform Creation Hardware Platform Verification (Simulation) Software Platform Creation Software Application Creation and Software Verification (Debugging) Creating/Importing User Defined Peripherals Platform Generator (PlatGen) Creates an implementation netlist of a bus-based subsystem Library Generator (LibGen) Generates libraries and drivers for embedded processors Simulation Generator (SimGen) Generate a simulation environment including simulation models, HDL wrappers, and simulation scripts Xilinx Microprocessor Debug (XMD) Facilitates a unified GDB interface as well as a Tcl interface for debugging programs GNU Debugger (GDB) Provides a unified interface for debugging/verifying MicroBlaze and PowerPC systems during various development phases Create/Import Peripheral Wizard (CreateIP) Create your own peripherals and import them into EDK compliant repositories or Xilinx Platform Studio (XPS) projects MHS (Microprocessor Hardware Specification) - Defines the components of a embedded system processor system, including: Bus Architecture, Peripherals, Processor, Address Space, External Ports, Interrupt Request priorities and the connectivity of the system MSS (Microprocessor Software Specification) - Contains directives for customizing operating systems, libraries, drivers and file systems MPD (Microprocessor Peripheral Description) - Defines the interface of the peripheral. It lists ports, bus interfaces, parameters and default values. MHS overwrites MPD MDD (Microprocessor Driver Definition) - Contains directives for customizing software drivers PAO (Peripheral Analyze Order) - Contains a list of HDL files that are needed for synthesis and defines the analyze order for compilation. Used when the user peripheral is in HDL format BBD (Black Box Definition) - Manages the file locations of optimized hardware netlists for the black box sections of a peripheral design. Used when the user peripheral is in netlist format BMM (BlockRAM Memory Map) - Contains a syntactic description of how individual BlockRAMs constitute a contiguous logical data space Embedded SystemsCheat Sheet • Simulation libraries compilation • Set enviroment variable MODELSIM = <modelsim>\modelsim.ini • Set environment variable MTI = <modelsim>\win32 • compxlib –s mti_se –f all –l vhdl from <xilinx>/vhdl/src directory • compxlib –s mti_se –f all –l verilog from <xilinx>/verilog/src directory • compedklib –X . –o edklib from <xilinx>/vhdl/mti_se directory
