Many of the levels are shown pictorially in the Gajski/Kuhn chart. Although VHDL does not support system description at the physical/geometry level of. Historical Perspective: Gajski and Kuhn’s Y-chart. • In Gajski and Kuhn’s Y- chart, each axis represents a view of a model: behavioral, structural, or physical view. Gajski-Kuhn chart – also known as Y-chart represents 3 views of a hardware design model. I am not sure how much this is applied practically. A good practice in.

According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y.

Languages Deutsch Edit links. On the system levelbasic properties of an electronic system are determined. For the behavioural description, block diagrams are used by making abstractions of signals and their time response. In the structural view, this is displayed with gates and flip-flops. The designer can select one of the perspectives and then switch from one view to another. Along these axis, the abstraction levels that describe the degree of abstraction.
Each of the domains can be divided into levels of abstraction, using concentric rings. Generally, the design process is not following a specific sequence in this diagram. In the geometric tajski, the design step of the floorplan is located. In the structural domain, blocks like ALUs are in use.
Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering InRobert Walker and Donald Thomas refined it. The register-transfer level RTL is a more detailed abstraction level on which the behaviour between communicating registers and logic units is described.

Creating a chxrt description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis.
The outer shells are generalisations, the inner ones refinements of the same subject.
Creating a physical description from a structural one is achieved through layout synthesis. Daniel Gajski and Robert Kuhn developed it in The three domains of the Gajski-Kuhn Y-chart are on radial axes.
Views Read Edit View history. The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices. At the top level outer ring gaajski, we consider the architecture of the chip; at the lower levels inner ringswe successively refine the design into finer detailed implementation: Computer engineering Electronic design automation Diagrams.

This is chatt by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels. Oder frag auf Deutsch auf TeXwelt.
