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 gjaski perceived within three domains that are depicted as three axis and produce a Y. Generally, the design process is not following a specific sequence in this diagram. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering Blocks used in the structure domain are CPUsmemory chipetc.

Gajski and Kuhn’s Y Chart

This is perceived by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels. The issue chat hardware development is most often a top-down design problem. From Wikipedia, the free encyclopedia. At the top level outer ringwe consider the architecture of the chip; at the lower levels inner yajskiwe successively refine the design into finer detailed implementation:. In the geometric view, the design step of the gaski is located.


The designer can select one of the perspectives and then switch from one view to another. Retrieved from ” https: This corresponds to transistors and capacitors up to crystal lattices. For the behavioural description, block diagrams are used by making abstractions of signals and their time response.

In the geometric domain, the logical level is described by standard cells.

Gajski-Kuhn chart

On the system levelbasic properties of an electronic system are determined. Oder frag auf Deutsch auf TeXwelt. Creating a physical description from a structural one is achieved through layout synthesis.

Examples Resources Builds Questions. Gajaki page was last edited on 10 Octoberat Here, data structures and data flows are defined. Cnart the structural view, this is displayed with gates and flip-flops. Daniel Gajski and Robert Kuhn developed it in Views Read Edit View history. Each of the domains can be divided into levels of abstraction, using concentric rings.

The behaviour of the circuit level is described by mathematics using differential equations or logical equations. Computer engineering Electronic design automation Diagrams. By using this site, you agree to the Terms of Use and Privacy Policy. The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments.


The outer shells are generalisations, the inner ones refinements of the same subject. The register-transfer level RTL is a more detailed abstraction level on which the behaviour between communicating registers and logic units is described.

The three domains of the Gajski-Kuhn Y-chart are on radial axes. InRobert Walker and Donald Thomas refined it.

Just ask in the LaTeX Forum. Along these axis, the abstraction levels that describe the degree of abstraction. In the structural domain, blocks like ALUs are in use.

The logical level is described in the behaviour perspective by boolean equations. Languages Deutsch Edit links. 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:
