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
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. The logical level is described in the behaviour perspective by boolean equations. In the geometric view, the design step of the floorplan is located. Here, data structures and data flows are defined.
Just ask in the LaTeX Forum.
The three domains of the Gajski-Kuhn Y-chart are on radial axes. Examples Resources Builds Questions.
In the geometric domain, the logical level is described by standard cells. Oder frag gajskii Deutsch auf TeXwelt. The register-transfer level RTL is a more detailed abstraction level on which the behaviour between communicating registers and logic units is described.
Comments Adding comments is currently not enabled. Daniel Gajski and Robert Kuhn developed it in 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:.
Along these axis, the abstraction levels that describe the degree of abstraction. The Gajski-Kuhn Y-chart is a model 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: Ti k Z Community Weblog.
Retrieved from ” https: The issue in hardware development is most often a top-down design problem. Creating a physical description from a structural one is achieved through layout synthesis. Each of the domains can be divided into levels of abstraction, using concentric rings. Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis.
Views Read Edit View history. In the structural domain, blocks like ALUs are in use.
The behaviour of the circuit level is described by mathematics using differential equations or logical equations. According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y.
This corresponds to transistors and capacitors up to crystal lattices. From Wikipedia, the free encyclopedia.
This page was last edited on 10 Octoberat Blocks used in the structure domain are CPUsmemory chipetc.

On the system levelbasic properties of an electronic system are determined. The outer shells are generalisations, the inner ones refinements of the same subject.
This is perceived gajskki 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.
