Unreferenced date December 2009 A function blockdiagram is a blockdiagram that describes a function between input variables and output variables. A Function computer science function is described as a set of elementary blocks. Input and output variables are connected to blocks by connection lines. An output of a block may also be connected to an input of another block Image Functional blockdiagram of the attitude control and maneuvering electronics system .jpg thumb 420px Functional blockdiagram of the attitude control and maneuvering electronics system. June 1962. Inputs and outputs of the blocks are wired together with connection lines, or links. Single lines may be used to connect two logical points of the diagram An input variable and an input of a block An output of a block and an input of another block An output of a block and an output variable The connection is oriented, meaning that the line carries associated data from the left end to the right end. The left and right ends of the connection line must be of the same type. Multiple right connection, also called divergence can be used to broadcast information from its left end to each of its right ends. All ends of the connection must be of the same type. Function blockdiagram is one of five languages for logic or control computer configuration configuration supported by standardization standard IEC 61131 3 for a control system such as a Programmable Logic Controller PLC or a Distributed Control System DCS .

Communication diagrams represent a combination of information taken from Class diagram Class , Sequence diagram Sequence , and Use case diagram Use Case Diagrams describing both the static structure and dynamic behavior of a system. However, communication diagrams use the free form arrangement of objects and links as used in Object diagrams. In order to maintain the ordering of messages in such a free form diagram, messages are labeled with a chronological number and placed near the link the message is sent over. Reading a communication diagram involves starting at message 1.0, and following the messages from object to object. Communication diagrams show a lot of the same information as sequence diagrams, but because of how the information is presented, some of it is easier to find in one diagram than the other. Communication diagrams show which elements each one interacts with better, but sequence diagrams show the order in which the interactions take place more clearly.

The Y Diagramm depicts the different perspectives in the hardware design. Mostly, it is used for the development of integrated circuit s. Daniel D. Gajski and Robert Kuhn developed it in 1983. In 1985, Robert Walker and Donald Thomas refined it. According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y. Along these axis, the abstraction levels that describe the degree of abstraction. The outer shells are generalisations, the inner ones refinements of the same subject. The issue in hardware development is most often a top down design problem. This is perceived by the three domains of behaviour, structure, and the layout that goes top down to more detailed abstraction levels. The designer can select one of the perspectives and then switch from one view to another. Generally, the design process is not following a specific sequence in this diagram. On the system level , basic properties of an electronic system are determined. For the behavioural description, block diagram s are used by making abstractions of signals and their time response. Blocks used in the structure domain are Central processing unit CPU s, Computer memory memory chip , etc. The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments . In the structural domain, blocks like Arithmetic logic unit ALU s are in use. The Register transfer language Register Transfer Level RTL is a more detailed abstraction level on which the behaviour inbetween communicating registers and logic units is described. Here, data structures and data flows are defined. In the geometric view, the design step of the floorplan is located. The logical level is described in the behaviour perspective by boolean equation s. In the structural view, this is displayed with Logical gate gate s and flipflop s. In the geometric domain, the logical level is described by standard cell s. The behaviour of the circu ... more details
