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.

Daniel Gajski and Robert Kuhn developed it in cuart The logical level is described in the behaviour perspective by boolean equations. Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis. The three domains of the Gajski-Kuhn Y-chart are on radial axes. Ti k Z Community Weblog.

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

Example: Gajski-Kuhn Y-chart

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


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

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

From Wikipedia, the free encyclopedia. This is perceived by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels.

Examples Resources Builds Questions. Computer engineering Electronic design automation Diagrams. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering The algorithmic level is gajsk by the definition of concurrent algorithms signals, loops, variables, assignments. This corresponds to transistors and capacitors up to crystal lattices.

Chaft page was last edited on 10 Octoberat In the structural domain, blocks like ALUs are in use.

The designer can select one of the perspectives and then switch from one view to another. In the geometric domain, the logical gxjski is described by standard cells. The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices.

In the geometric view, the design step of the floorplan is located. InRobert Walker and Donald Gzjski refined it. 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.


In the structural view, this is displayed with gates and flip-flops. Yajski, data structures and data flows are defined. The behaviour of the circuit level is described by mathematics using differential equations or logical equations. Generally, 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. Just ask chartt the LaTeX Forum. Oder frag auf Deutsch auf TeXwelt. The outer shells are generalisations, the inner ones refinements of the same subject. On the system levelbasic properties of an electronic chat are determined. Creating a physical description from a structural one is achieved through layout synthesis. Retrieved from ” https: Comments Adding comments is currently not enabled.
