   What is Fide?
   -------------

   Fide (Fuzzy Inference Development Environment) is a complete environment
   for the development of fuzzy logic-based systems.  Fide provides system
   engineers with the most effective fuzzy tools in the industry and runs in
   MS-Windows(TM)  on 386/486 hardware.  The price is $1495 and is available 
   now from Aptronix and authorized Motorola distributors.  The software 
   package comes with complete documentation on how to develop fuzzy logic 
   based applications, free telephone support for 90 days and access to 
   the Aptronix	FuzzyNet information exchange.
   
   Fide employs a friendly and useful tool for each level of debugging,
   including data tracing, analysis and simulation.  These tools present the
   inference unit's behavior from the perspective of the user and enable
   interactive debugging of the fuzzy model and the inference process.  If
   the inference unit does not perform as expected, these tools lead the user
   to the bug location in the source code.  Engineers will feel comfortable
   developing applications with Fide because the interaction of the tools
   follow a traditional programming approach of design, simulation and
   analysis.
   
   Specify the fuzzy inference system effectively
   ----------------------------------------------

   Fide is based on a language called FIL (Fuzzy Inference Language).  Because
   FIL is a non-sequential language with English-like statements, using FIL
   is very easy.  Although simple to learn, FIL incorporates the most
   efficient inference methods and a rich variety of logic operators for
   different applications.  FIL also provides optimized flexibility for
   membership function representation and the data types required by separate
   target processors.
   
   Take advantage of an open architecture that offers easy compatibility
   ----------------------------------------------------------------------

   For the first time, a complete standard for fuzzy systems is combined into
   one unit called FSSE, Aptronix's fuzzy system standard environment.  In
   order to provide the user with an open architecture environment, Aptronix
   has made FSSE available to the public.  FSSE consists of data formats for
   membership functions, inference rules, inference units and other fuzzy
   inference parameters.
   
   Simulation instead of fabrication
   ---------------------------------

   Testing a system is usually expensive, time consuming and sometimes
   impossible.  With Fide engineers can design, simulate and perfect an
   entire dynamic system, including hardware, before building anything.  
   Engineers can perfect designs and examine trade-offs while avoiding costly
   errors in the fabrication or assembly stages of construction.
   
   Get the product to market faster
   --------------------------------

   Fide's integrated tools provide the most efficient environment to debug,
   analyze and simulate the behavior of a system.  The time from conceptual
   design to testing and implementation is reduced dramatically.
   
   

                    HOW TO USE FIDE IN THREE EASY STEPS
                    -----------------------------------

   A fuzzy logic system is based on fuzzy inference units integrated with
   non-fuzzy units.  Fide is designed to cover the entire spectrum of the
   system design process, both at the unit and system level.  To design a
   fuzzy inference unit, follow these three steps:
   
    
                      STEP #1 - Write the source code.
   
   All source code is written in FIL (the language for fuzzy inference). 
   Specify the input/output variables, the membership functions associated
   with them, and the inference rules with FIL.  If the system requires
   special logic operators and inference methods, FIL provides the capability
   to tailor the source code for specific requirements.
   
    
   Use the Fide graphic editor to draw a graph of the membership function (as
   opposed to using a text editor and FIL to describe a membership
   function.)  The editor automatically converts the graph into a segment of
   code.  The Fide compiler translates the source code into the Aptronix
   standard data structure.
   
   
                          Step #2 - Debug the code
   
   Fide provides an elegant way to view a unit from multiple perspectives via
   three powerful debug tools. 
   
                                   TRACER
   
    
         A. By using the Fide tracer, designers can set the input
         variable to any test value and observe the output
         value.  If undesired results occur, it is easy to
         trace into the details of the inference process, step
         by step, and locate the specific location where the
         source code can be edited and the bug fixed.
      
   
   
                                  ANALYZER
   
       
         B. The next debug tool is the Fide analyzer which
         displays a global view of the transfer function
         response.  Here, input/output relationships are
         displayed as a three dimensional structure.  Advanced,
         interactive 3-D graphics let users check the function
         in detail, examining the surface from a variety of
         perspectives.   Aptronix has made an important 
         advancement in debugging technology by combining the
         analyzer and simulator with the tracer.  Using a
         hot-link to the tracer, engineers can trace the
         inference process at any selected point on the surface
         -- even to the source level.
         
   
   
                                 SIMULATOR
   
      
         C.  The final debug tool is the Fide simulator.  It
         runs the unit with input values prepared in an input
         value file.  The  simulator displays curves of the
         output values and simulates the unit's dynamic
         behavior.  Again, a hot-link to the tracer is provided
         for immediate access to the source code level
         providing unprecedented debugging capability.
         
      
                  Step #3 -- Generate the real-time code.
   
    
         Once a processor has been selected for implementation,
         the corresponding Fide RTC (real-time code) generator
         can be used for that chip.  If the unit is implemented
         in software, the Aptronix run-time library, when 
         linked into a C program, performs the fuzzy inference
         computation.
         
         
             System integration with Fide using Composer
             -------------------------------------------
   
   There is a unique way of graphically simulating and testing a system
   of fuzzy inference units and application specific code with Aptronix
   Composer.  When using the Composer, a system is regarded as an open or
   closed loop consisting of units connected with data transfer
   channels.  In addition to fuzzy inference units, users can integrate
   other software modules, such as operation units (performing
   mathematical operations) and/or execution units (describing prepared
   software modules). 
      
      
      
                               COMPOSER
   
    
      Source code can be written or drawn using the graphical
      editor.  The system integration language, called FCL
      (Fide Composer Language) has textual and graphical
      representations.  In its graphical representation, a
      system is described by drawing a chart of data flow
      paths between units.  In its textual representation, a
      system is described by listing the units and the data
      transferred between them.
      
      The Composer textual editor and Composer graphical
      editor are used to design and modify the system and a
      built-in converter can change one representation to
      the other.  To test the system, the data flow viewer
      or the dynamic simulator is used.
      
      The data flow viewer allows testing of the unit by
      setting input values and observing the details of data
      flow in the system.  If a fuzzy inference
      unit is found to have an undesired response, a
      hot-link automatically takes the user to the tracer.
   
      The dynamic simulator analyzes the dynamic behavior of
      the system.  The user initializes the system with any
      values, sets terminating conditions and then lets the
      system run automatically.  When the terminating
      conditions are met, the values of all selected
      input/output variables are displayed as time-value
      graphs.
      
   

   Applications
   ------------
      
   Fuzzy logic can improve system performance and reduce design time and cost
   in a wide range of applications. Such as:
   
   Automotive
   
   In order to improve quality, performance, and shorten development cycles,
   major automotive manufacturers are now using fuzzy technology.  Typical
   applications include fuzzy engine control, fuzzy cruise control, fuzzy
   anti-lock braking systems and fuzzy transmission systems.
   
   Aerospace
   
   The aerospace industry requires real-time high-performance systems that
   present difficult problems for engineers.  Fuzzy technology proves new and
   useful methods of approaching design of these challenging systems.
   
   Appliances
   
   Fuzzy technology simplifies the product design and development cycle,
   lowers production costs, and improves product performance.  Many consumer
   manufacturers have been quick to implement fuzzy technology into new
   products such as washing machines, air conditioners, cameras, VCRs and
   televisions.
   
   Chemical
   
   The complexity of system modeling is a very difficult problem in the
   chemical industry. The descriptive modeling feature of fuzzy logic makes
   it an idea tool for complex systems design.
   
   General Manufacturers
   
   Fuzzy logic-based real-time diagnosis and control systems are invaluable
   for increasing equipment efficiency and diagnosing malfunctions.
   
   Civil Engineering
   
   Traditional system analysis and assessment are based on inexact conceptual
   models which may lead to errors in system analysis.  Since fuzzy
   technology describes the system more accurately, the assurance of systems
   analysis is increased.
   
   Finance
   
   Fuzzy systems provide a methodology for modeling the uncertainly in market
   trends and risk analysis.  Using fuzzy logic, the financial world can
   develop models that are more realistic.
   
   Education
   
   Academic institutions can use Fide to reach and perform research in fuzzy
   inference-based systems design and related work.  Aptronix has close ties
   with the research community through it's University Program.  Through this

                           BACKGROUND INFORMATION
                           ----------------------
   
                            What is fuzzy logic?
   
   Fuzzy logic is a powerful problem-solving methodology with a myriad of
   applications in embedded control and information processing.  Fuzzy logic
   provides a remarkably simple way to draw definite conclusions from vague,
   ambiguous or imprecise information.  In a sense, fuzzy logic resembles
   human decision making with its ability to work from approximate data and
   find precise solutions.
   
   Fuzzy logic is based on fuzzy set theory.  Unlike traditional " either/or"
   set theory, fuzzy logic does not impose rigid classifications such as true
   or false, black and white, 0 or 1, etc.  Membership in fuzzy sets is a 
   continuous phenomenon, with values ranging from 0 to 1.  This allows
   programmers to model vague and subjective concepts such as "very hot,"
   "bright red," and "a long time".
   
   
                            Why Use Fuzzy logic?
   
   Using fuzzy logic, system designers can realize lower development costs,
   superior features, and better end product performance.  Most importantly,
   products can be brought to market faster and more cost-effectively. 
   Several factors make fuzzy logic desirable to the system designer.
   
   1. Describe and model solutions to a problem without having to use complex
   mathematical models for systems and development.
   
   2. Optimize a known solution in order to obtain a simpler and more
   effective implementation.
   
   3. Simplify the system design process, thereby decreasing development
   costs.
   
   4. Make the system more descriptive.  A system is more convenient to
   manage, maintain, upgrade and is easier to differentiate with less
   risk.
   
   5. Have a higher fault-tolerance and a better trade-off between system
   robustness and system sensitivity.
   
   6. Provide products with powerful features and performance within a price
   range unmatched by other solutions.
