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.

Gajski and Kuhn’s Y Chart

Gajwki of the domains can be divided into levels of abstraction, using concentric rings. This is perceived by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels.

The logical level is described in the behaviour perspective by boolean equations. Oder frag auf Deutsch auf TeXwelt. Creating a physical description from a structural one is achieved through layout synthesis. InRobert Walker and Donald Thomas refined it.

The algorithmic level is defined by the definition of gaajski algorithms signals, loops, variables, assignments. Languages Deutsch Edit links. Blocks used in the structure domain are CPUsmemory chipetc. Examples Resources Builds Questions. The behaviour of the circuit level is described by mathematics using differential equations or logical equations.

Views Read Edit View history. In the geometric view, the design chsrt of the floorplan is located. The designer can select one of the perspectives and then switch from one view to another. For the behavioural description, block diagrams are used by making abstractions of signals and their time response.

On the system levelbasic properties of an electronic system are determined. This corresponds to transistors and capacitors up to crystal lattices. In the structural view, this is displayed hcart gates and flip-flops. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering The register-transfer level RTL is a more detailed abstraction level on which the behaviour between communicating registers and logic units is described.

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:. This page was last edited on 10 Octoberat According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y.

Example: Gajski-Kuhn Y-chart

The outer shells are generalisations, the inner ones refinements of the same subject. From Wikipedia, the free encyclopedia. Daniel Gajski and Robert Kuhn developed it in Just ask in the LaTeX Forum. Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis.


Here, data structures and data flows are defined.

Computer engineering Electronic design automation Diagrams. The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices.

The three domains of the Gajski-Kuhn Y-chart are on radial axes.

In the geometric domain, the logical level is described by standard cells. Retrieved from ” https: Along these axis, the abstraction levels that describe the degree of abstraction. 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: The issue in hardware development is most often a top-down design problem.
