DEEDSDigital Electronics Education and Design
Suite
A digital systems simulation tool
specifically designed for educational
applications
  • The Deeds suite is composed by three simulators
  • d-DcS Digital Circuit Simulator
  • d-FsM Finite State Machine Simulator
  • d-McE Microcomputer Board Emulator
  • http//www.esng.dibe.unige.it/Projects/Netpro/Deed
    s/index.htm

DEEDS The browsers
  • The browsers show a list of the assignments and
    a specific assignment.
  • Text and objects in the page can be active, i.e.
    associated to simulation functions.
  • The browser interacts with simulators, providing
    a true interaction between problems and
    experiments (e.g. by clicking on the schematics,
    the circuit is loaded in the Digital Circuit
    Simulator, and can be tested or modified)

10
DEEDS The d-DcS Digital Circuit Simulator
  • The d-DcS has been designed to be easy to use,
    while maintaining quasi-professional features
  • The user interface is intuitive
  • The choice of digital components is based on
    their logical function, not on commercial lines
  • Two simulation modes
  • Interactive AnimationIn the interactive
    animation mode the simulator processes input
    commands and displays output values
  • Timing diagram

11
DEEDS - The d-FsM Simulator
  • Finite state machines (FSM) are designed with
    Algorithmic State Machine (ASM) charts
  • Algorithms can be functionally tested (with a
    timing diagram), without circuit syntesis
  • A FSM produced with the this tool can be used as
    a component by the d-DcS
  • A FSM can also be exported in VHDL language, to
    allow reusing it in professional design tools

12
DEEDS the d-McE mC Emulator
  • The Microcomputer Board Emulator is based on an
    eight bits microprocessor, a RAM and ROM memory
    system and a parallel input/output port system
  • The 8-bit micro-processor is the DMC8 (a revised
    and simplified version of the well-known
    Z80-CPU)
  • The board in figure is a representation of a
    possible hardware implementation of the emulated
    microcomputer

13
DEEDS the d-McE mC Emulator (2)
  • The architecture of the Microcomputer Board is
    classical
  • The board interfaces with the external world
    through four input and four output parallel ports
  • Address and data busses are not available outside
    the board, but port control signals are available
    for possible extension of the ports
  • Clock, Reset and Interrupt signal are available

14
DEEDS the d-McE mC Emulator (3)
  • The Microcomputer Board is a component of the
    library of the d-DcS
  • A digital circuit, embedding one or more
    Microcomputers, can be simulated by the d-DcS
  • The embedded Microcomputer can be programmed with
    the d-McE tool.
  • This feature opens a whole world of
    state-of-the-art educational application

15
DEEDS the d-McE mC Emulator (4)
  • The Microcomputer Board Emulator allows to edit
    assembly code with syntax highlighting
  • Assembling, linking and loading operation are
    transparent to the user
  • The Microcomputer Board Emulator allows to debug
    the program step-by-step or in animation mode
  • The interactive visual debugger shows memory,
    registers and ports contents
  • The tool allows a full control of the
    microcomputer operations, including I/O
    operations

16
ISILab
  • Functionalities
  • Interactivity between users and measurement
    instruments.
  • Management of repeated sequence of data
    acquisition, computation and presentation.
  • Real-time feedback from the test bench
    (human-in-the-loop case).
  • Uniqueness of resources (instruments are real
    devices connected to specific systems under
    test).
  • Instruments synchronization, when more
    instruments are involved in a measurement.
  • Test-bench access control (exclusive access or
    multi-user concurrent access).

ISILab (2)
  • Current version (0.1)
  • Core engine in LabVIEW
  • GUIs are applets
  • Assignments are part of the experiments
  • Next version (0.2) will be available in few
    months
  • Totally based on web services
  • Use of workflows to define measures
  • Developed with the Web Services Resource
    Framework .NET
  • GUIs are ASP.NET web pages (AJAX technology will
    follow)
  • Assignments will be delivered via the LMS
  • A protoype is available at
  • http//netlab2-esng.dibe.unige.it/WSRFRemoteL
