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.

Computer engineering Electronic design automation Diagrams. Views Read Edit View history. In the structural domain, blocks like ALUs are in use. Blocks used in the structure domain are CPUsmemory chipetc. Creating a physical description from a structural one is achieved through layout synthesis.
For the behavioural description, block diagrams are used by making abstractions of signals and their hcart response. In the geometric view, the design step of the floorplan is located.
Just ask in the LaTeX Forum. The outer shells are generalisations, the inner ones refinements of the same subject. The designer can select one of the perspectives and then switch from one view to another.

This page was last edited on 10 Octoberat Examples Resources Builds Questions. The logical level is described in the behaviour perspective by boolean equations. Comments Gajdki comments is currently not enabled.
This is perceived by the three domains of behaviour, ggajski, and the gaiski that goes top-down to more detailed abstraction levels. The issue in hardware development is most often a top-down design problem. According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y. Oder frag auf Deutsch auf TeXwelt.
The three domains of the Gajski-Kuhn Y-chart are on radial axes. The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices. The behaviour of the circuit level is described by mathematics using differential equations charr logical equations. 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: This corresponds to transistors and capacitors up to crystal lattices.
Gajski and Kuhn’s Y Chart
Generally, the design process is not following a specific sequence in this diagram. Creating a structural description from a behavioural one is achieved through the processes of high-level synthesis or logical synthesis.
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. In the geometric domain, the logical level is described by standard cells. InRobert Walker and Donald Thomas refined it.
Each of the domains can be divided into levels of abstraction, using concentric rings. 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:. Features Coordinate systems 8 Tags Charts 23 Scientific and technical areas Computer science 42 Electrical engineering Here, data structures and data flows are defined.
The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments. Along these axis, the abstraction levels that describe the degree of abstraction.
