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.

Along these axis, the abstraction levels that describe the degree of abstraction. In the geometric view, the design step of the floorplan is located.

Example: Gajski-Kuhn Y-chart

Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis. From Wikipedia, the free encyclopedia.

For the behavioural description, block diagrams are used by making abstractions of signals and their time response. Views Read Edit View history. The designer can select one of the perspectives and then switch from one view to another.

In the structural view, this is displayed with gates and flip-flops. In the structural domain, blocks like ALUs are in use. Just ask in the LaTeX Forum. Comments Adding comments is currently not enabled. The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices. Creating a physical description from a structural one is achieved through layout synthesis.

The outer shells are generalisations, the inner ones refinements of the same subject. The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments.

Retrieved from ” https: Examples Resources Builds Questions. The register-transfer level RTL is a more detailed abstraction level on which the behaviour between communicating registers and logic units is described.

Blocks used in the structure domain are CPUsmemory chipetc. This corresponds to transistors cbart capacitors up to crystal lattices. Here, data structures and data flows are defined.

In the geometric domain, the logical level is described by standard cells. By using this site, you agree to the Terms of Use and Privacy Policy. Ti k Z Community Weblog. Generally, the design process is not following a specific sequence in u diagram. The logical level is described in the behaviour perspective by boolean equations. Each of the domains can be divided into levels of abstraction, using concentric rings.

Languages Deutsch Edit links. According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y.

The three domains of the Gajski-Kuhn Y-chart are on radial axes. 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 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 This page was last edited on 10 Octoberat On the system levelbasic properties of an electronic system are determined. Daniel Gajski and Robert Kuhn developed it in This is perceived by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels.
