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.

Just ask in the LaTeX Forum. In the geometric view, the design step of the floorplan is located.

For the behavioural description, block diagrams are used by making abstractions of signals and their time response. Creating a physical description from a structural one is achieved through layout synthesis.

Example: Gajski-Kuhn Y-chart

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

Along these axis, the abstraction levels that describe the degree of abstraction.

Gajski and Kuhn’s Y Chart

The designer can select one of the perspectives and then switch from one view to another. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering On the system levelbasic properties of an electronic system are determined.

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: By using this site, you agree to the Terms of Use and Privacy Policy. This page was last edited on 10 Octoberat Retrieved from ” https: The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments.

This corresponds to transistors and capacitors up to crystal lattices. Examples Resources Builds Charf. From Wikipedia, the free encyclopedia.

Gajski and Kuhn’s Y Chart

GajsoiRobert Walker and Donald Thomas refined it. Generally, the design process is not following a specific sequence in this diagram. The register-transfer level RTL is a more detailed abstraction level on which the behaviour between communicating registers and logic units is described.

The issue in hardware development is most often a top-down design problem. Comments Adding comments is currently not enabled.

Gajski-Kuhn chart – Wikipedia

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


The logical level is described in the behaviour perspective by boolean equations. In the geometric domain, the logical level is described by standard cells.

Ti k Z Community Weblog. In the structural view, this is displayed with gates and flip-flops. In the structural domain, blocks like ALUs are in use. Views Read Edit View history. Here, data structures and data flows are defined.

The three domains of the Gajski-Kuhn Y-chart are on radial axes. Oder frag auf Deutsch auf TeXwelt. The Gajski-Kuhn Y-chart is a gamski which captures the considerations in designing semiconductor devices.

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:.

According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y. Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis. Daniel Gajski and Robert Kuhn developed it in
