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.

In the geometric view, the design step of the floorplan is located. This page was last edited on 10 Octoberat Generally, the design process is not following a specific sequence in this diagram.

On the gahski levelbasic properties of an electronic system are determined. The designer can select one of the perspectives and then switch from one view to another. This gajsii to transistors and capacitors up to crystal lattices. 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 outer shells are generalisations, the inner ones refinements of the same subject.


For the behavioural description, block diagrams are used by making abstractions of signals and their time response. This is perceived by the three domains of behaviour, structure, and the layout that goes top-down to more detailed abstraction levels. Just ask in the LaTeX Forum.

Computer engineering Electronic design automation Diagrams. The Gajski-Kuhn Y-chart is a model which captures the considerations in designing semiconductor devices. Oder frag auf Deutsch auf TeXwelt.

In the geometric domain, the logical level is described by standard cells. Each of the domains can be divided into levels of abstraction, using concentric rings.

Here, data structures and data flows are defined. The issue in hardware development is most often a top-down design problem. Along these axis, the abstraction levels that describe the degree of abstraction.


Blocks used in the structure domain are Cgartmemory chipetc. Retrieved from ” https: Comments Adding comments is currently not enabled.

Gajski and Kuhn’s Y Chart

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. In the structural domain, blocks like ALUs are in use. The logical level is described in the behaviour perspective by boolean equations.

The algorithmic level is defined by the definition of concurrent algorithms signals, loops, variables, assignments.

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