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.

Languages Deutsch Edit links. The logical level is described in the behaviour perspective by boolean equations. 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 designer can select one of the perspectives and then switch from one view to another. Retrieved from ” https: The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices. By using this site, you agree to the Terms of Use and Privacy Policy.


In the geometric view, the design step of the floorplan is located. This corresponds to transistors and capacitors up to crystal lattices. In the structural view, this is displayed with gates and flip-flops. Creating a physical description from a structural one is achieved through layout synthesis.

Gajski-Kuhn chart – Wikipedia

Gajskj, the design process is not following a specific sequence in this diagram. Each of the domains can be divided into levels of abstraction, using concentric rings. Ti k Z Community Weblog. For the behavioural description, block diagrams are used by making abstractions of signals and their time response. Computer engineering Electronic design automation Diagrams.

Gajski and Kuhn’s Y Chart

Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis. Daniel Gajski and Robert Charg developed it in In the structural domain, blocks like ALUs are in use.

The register-transfer level RTL is a more detailed abstraction level on which the behaviour between communicating registers and logic units is described.

Here, data structures and data flows are defined. According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y. On the system levelbasic properties of an electronic system are determined.

The issue in hardware development is most often a top-down design problem. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering Along these axis, the abstraction levels that describe the degree of abstraction. This is perceived by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels.

The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments.

Examples Resources Builds Questions. 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: Blocks used in the structure domain are CPUsmemory chipetc. From Wikipedia, the free encyclopedia. This page was last edited on 10 Octoberat The three domains of the Gajski-Kuhn Y-chart are on radial axes.

InRobert Walker and Donald Thomas refined it. The behaviour of the circuit level is described by mathematics using differential equations or logical equations.
