What is Y chart in VLSI?

The Gajski-Kuhn chart (or Y diagram) depicts the different perspectives in VLSI hardware design. Mostly, it is used for the development of integrated circuits. According to this model, the development of hardware is perceived within three domains that are depicted as three axis and produce a Y.

What is VLSI design flow explain with Y chart?

Y Chart. The Gajski-Kuhn Y-chart is a model, which captures the considerations in designing semiconductor devices. The three domains of the Gajski-Kuhn Y-chart are on radial axes. Each of the domains can be divided into levels of abstraction, using concentric rings.

What is VLSI design process?

Very large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit chips were widely adopted, enabling complex semiconductor and telecommunication technologies to be developed.

Does VLSI require coding?

Even more basic understanding of electrical energy and also complete knowledge of electrical components such as inductor, capacitor resistor, and their mathematical behaviour is required for a VLSI design engineer. Than only comes the importance of HDL programming/coding.

What are the 5 levels in VLSI design?

Physical level : Rectangles, design rules. Circuit level : Transistors, R and C, analog voltage/current values. Switch level: Transistors, R and C, multi-valued logic.

Does VLSI have future?

The industry will sustain itself with a slow growth period until disruptive technology emerges like QC. Customized solutions will emerge in the market like accelerator designs. There is a renewed interest where people have started concentrating on merging VLSI + Computer architecture and system designs.

Which design is faster in VLSI?

Which design is faster? Explanation: Gate array design is faster than a prototype full-custom design and the final custom designs must be carefully optimized. 6.

Which software is used for VLSI design?

Cadence is the most widely used , and the most professional, software for IC layout designing, however there are many other tools like mentor graphics tool, tanner, and also other open source tools like glade, and electric. There are many VLSI IC layout tools.

Which is the typical design flow for VLSI?

The Y-chart (first introduced by D. Gajski) shown in Fig. 1.4 illustrates a design flow for most logic chips, using design activities on three different axes (domains) which resemble the letter Y. Figure-1.4: Typical VLSI design flow in three domains (Y-chart representation).

What does a Y chart in VLSI represent?

In terms of abstraction, the outer ring in the chart is the highest level of abstraction and it decreases as you move to the center of the chart. It is captured as “System level” in the outer ring and as you move down – “algorithmic” Gajski-Kuhn chart – also known as Y-chart represents 3 views of a hardware design model.

Why is VLSI used in the IC industry?

VLSI lets IC designers add all of these into one chip. The electronics industry has achieved a phenomenal growth over the last few decades, mainly due to the rapid advances in large scale integration technologies and system design applications.

What are the three different domains of VLSI?

The three different domains are behavioural,structural and physical/geometry domain which are on radial axis.Each of the corresponding domains can be further divided into levels of abstraction using concentric rings and each of the domain falling within the circle forms a group and keep going on in a top down fashion towards the centre of the core.
