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.

The register-transfer level RTL is a more detailed abstraction level on chqrt 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. This page was last edited on 10 Octoberat Generally, the design process is not following a specific sequence in this diagram.

Computer engineering Electronic design automation Diagrams. Daniel Gajski and Robert Kuhn developed it in The behaviour of the circuit level is described by mathematics using differential equations or logical equations. The logical level is described in the behaviour perspective by boolean equations.


The issue in hardware development is most gajsoi a top-down design problem.

This corresponds to transistors and capacitors up to crystal lattices. In the geometric view, the design step of the floorplan is located.

The outer shells are generalisations, the inner ones refinements of the same subject. Retrieved from ” https: Views Gajskii Edit View history. The three domains of the Gajski-Kuhn Y-chart are on radial axes.

For the behavioural description, block diagrams are used by making abstractions of signals and their time response.

Gajski and Kuhn’s Y Chart

From Wikipedia, the free encyclopedia. Each of the domains can be divided into levels of abstraction, using concentric rings. In the structural view, this is displayed with gates and flip-flops. According to this model, gajki development of hardware is perceived within three domains that are depicted as three axis and produce a Y. Creating a physical description from a structural one is achieved through layout synthesis.

InRobert Walker and Donald Thomas refined it. Oder frag auf Deutsch auf TeXwelt. This is perceived by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels.

In the geometric domain, the logical level is described by standard cells. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering The designer can select one of the perspectives and then switch from one view to another.

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

Languages Deutsch Edit links. Blocks used in the structure domain are CPUsmemory chipetc.

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

In the structural domain, blocks like ALUs are in use.

The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices. Here, data structures and data flows are defined. Along these axis, the abstraction levels that describe gaski degree of abstraction.
