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

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).
