What is IC design flow?

What is IC design flow?

IC design flow is the process of developing an IC design to the point at which the IC can be manufactured in a semiconductor fabrication plant (i.e., a foundry).

What are the steps in VLSI design flow?

Summary of the different steps in a VLSI Design Flow

1. VLSI Design Flow Step 1: Logic Synthesis.
2. VLSI Design Flow Step 2: Floorplanning.
3. VLSI Design Flow Step 3: Synthesis.
4. VLSI Design Flow Step 4: Block Level Layout.
5. VLSI Design Flow Step 5: VLSI Level Layout.

How do you design and build ICS?

A typical IC design cycle involves several steps:

1. System Specification. Feasibility study and die size estimate.
2. Architectural or System Level Design.
3. Logic Design.
4. Circuit Design.
5. Physical Design.
6. Physical Verification & Signoff.
7. Mask data preparation (Layout Post Processing)
8. Wafer fabrication.

How many types of domains are there in VLSI design flow?

A single hierarchy may not be sufficient to describe the VLSI design process. There are three design domains namely behavioral domain, structural domain and physical domain each with its own hierarchy.

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 ASIC flow in VLSI?

ASIC design flow is a mature and silicon-proven IC design process which includes various steps like design conceptualization, chip optimization, logical/physical implementation, and design validation and verification.

What is the function of IC?

An IC can function as an amplifier, oscillator, timer, counter, logic gate, computer memory, microcontroller or microprocessor. An IC is the fundamental building block of all modern electronic devices.

What is VLSI design?

Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI lets IC designers add all of these into one chip.

What is the CAD tools used in VLSI design?

Overview of the IDA System: A Toolset for VLSI Layout Synthesis. The Integrated Design Aides (IDA) toolset is a set of VLSI CAD software programs that have been developed to make the most effective use possible of a designer’s time.

What is the relation between IC and VLSI design?

Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device.

Which is the first step in VLSI design flow?

System Specification The first step of VLSI Design Flow is system specifications. System specification is a high level representation of the system. The factors to be considered in this process include performance, functionality and interface.

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 does DRC do in VLSI design flow?

In this step we perform physical verification checks such as Layout Vs schematic (LVS) and Design Rule check (DRC). DRC verifies whether the given layout satisfies the design rules provided by the fabrication team.

What are the current trends in VLSI design?

The current cutting-edge technologies such as high resolution and low bit-rate video and cellular communications provide the end-users a marvelous amount of applications, processing power and portability. This trend is expected to grow rapidly, with very important implications on VLSI design and systems design.
