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.

This is perceived by the three domains of behaviour, structure, and the gajsli that goes top-down to more detailed abstraction levels. Examples Resources Builds Questions. Creating a physical description from a structural one is achieved through layout synthesis. Gauski corresponds to transistors and capacitors up to crystal lattices.
The three domains of the Gajski-Kuhn Y-chart are on radial axes. In the structural domain, blocks like ALUs are in use. This page was last edited on 10 Octoberat In the geometric view, the design step of the floorplan is located. The designer can select one of the perspectives and then switch from one view to another.
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:. Comments Adding comments is currently not enabled.
Daniel Gajski and Robert Kuhn developed it in From Wikipedia, the free encyclopedia. Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis.
Generally, the design process is not following a specific sequence in this diagram. In the structural view, this is displayed with gates and flip-flops.

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. In the geometric domain, the logical level is described by standard cells.
The outer shells are generalisations, the inner ones refinements of the same subject. Views Read Edit View history. 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: Computer engineering Electronic design automation Diagrams.
Gajski-Kuhn chart – Wikipedia
According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y. Languages Deutsch Edit links.
Along these axis, the abstraction levels that describe the degree of abstraction.
The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments. Retrieved from ” https: Gajsji ask in the LaTeX Forum.
Oder frag auf Deutsch auf TeXwelt. InRobert Walker and Donald Thomas refined it. The logical level is described in the behaviour perspective by boolean equations. Ti k Z Community Weblog. Blocks used in the structure domain are CPUsmemory chipetc. 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.
The register-transfer level RTL is a h detailed abstraction level on which the behaviour between communicating registers gajsmi logic units is described.
For the behavioural description, block diagrams are used by making abstractions of signals and their time response. The issue in hardware development is most often a top-down design problem.
