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.

On the system levelbasic properties of an electronic system are determined. Just ask in the LaTeX Forum.

Languages Deutsch Edit links. Each of the domains can be divided into levels of abstraction, using concentric rings. Computer ggajski Electronic design automation Diagrams. InRobert Walker and Donald Thomas refined it. This is perceived 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.

In the structural domain, blocks like ALUs are in use. Creating a physical description from a structural one is achieved through layout synthesis. Examples Resources Builds Questions. 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 structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis.


At the top level outer ringwe consider the architecture of the chip; at the lower levels inner ringswe successively refine the design into finer detailed implementation:.

Example: Gajski-Kuhn Y-chart

Here, data structures gajdki data flows are defined. The designer can select one of the perspectives and then switch from one view to another.

The logical level is described in the behaviour perspective by boolean equations. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering In the geometric domain, the logical level is described by standard cells. Along these axis, the abstraction levels that describe the degree of abstraction.

Gajski and Kuhn’s Y Chart

Generally, the design process is not following a specific sequence in this diagram. The algorithmic level is defined by the definition of gajs,i algorithms signals, loops, variables, assignments.

Comments Adding comments is currently not enabled. Gajjski the behavioural description, block diagrams are used by making abstractions of signals and their time response. Daniel Gajski and Robert Kuhn developed it in Retrieved from ” https: Ti k Z Community Weblog. The issue in hardware development is most often a top-down design problem.

Views Read Edit View history. In the geometric view, the design step of the floorplan is located. According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y.

In the structural view, this is displayed with gates and flip-flops. Blocks used in the structure domain are CPUsmemory chipetc.

Gajski and Kuhn’s Y Chart

The three domains of the Gajski-Kuhn Y-chart are on radial axes. By using this site, you agree to the Terms of Use and Privacy Policy.

The outer shells are generalisations, the inner ones refinements of the same subject. The behaviour of the circuit chxrt is described by mathematics using differential equations or logical equations.
