What is the ASIC design?
ASIC design is a methodology of cost and size reduction of an electronic circuit, product or system through miniaturization and integration of individual components and their functionality into a single element – an Application Specific Integrated Circuit (ASIC).
What is full custom ASIC design flow?
From Wikipedia, the free encyclopedia. Full-custom design is a methodology for designing integrated circuits by specifying the layout of each individual transistor and the interconnections between them.
What is synthesis in ASIC design flow?
Synthesis is the process of transforming your HDL design into a gate-level netlist, given all the specified constraints and optimization settings. Logic synthesis is the process of translating and mapping RTL code written in HDL (such as Verilog or VHDL ) into technology specific gate level representation.
What do you mean by design flow?
Design flows are the explicit combination of electronic design automation tools to accomplish the design of an integrated circuit. Many factors describe what drove the design flow from a set of separate design steps to a fully integrated approach, and what further changes are coming to address the latest challenges.
What are the steps in VLSI design flow?
Summary of the different steps in a VLSI Design Flow
- VLSI Design Flow Step 1: Logic Synthesis.
- VLSI Design Flow Step 2: Floorplanning.
- VLSI Design Flow Step 3: Synthesis.
- VLSI Design Flow Step 4: Block Level Layout.
- VLSI Design Flow Step 5: VLSI Level Layout.
What is VHDL in VLSI?
VHDL stands for very high-speed integrated circuit hardware description language. It is a programming language used to model a digital system by dataflow, behavioral and structural style of modeling. This language was first introduced in 1981 for the department of Defense (DoD) under the VHSIC program.
What is the first step in design flow?
The first step in the design flow is writing the synthesizable register transfer level (RTL) VHDL circuit model. The VHDL code describes the behaviour of the circuit. This part simulates the RTL VHDL model to make sure that it does what it was designed to do.
Why do we need ASIC?
In addition, an ASIC contains only the circuitry needed for the application, therefore, the chip is much more efficient due to the miniature size and power requirements. In addition to size, power and performance, ASIC chips provide you with IP protection, unlike a standard product. We design the chips specific to you.
What is design flow of VLSI?
VLSI Design Flow The various levels of design are numbered and the blocks show processes in the design flow. Specifications comes first, they describe abstractly, the functionality, interface, and the architecture of the digital IC circuit to be designed.
Which language is used for ASIC?
ASIC programming language

Which is the first step in the ASIC design flow?
Figure 1 shows the flow chart for the ASIC design flow. The first step in ASIC design flow is defining the specifications of the product before we embark on designing it. This phase typically involves market surveys with potential customers to figure out the needs and talking to the technology experts to gauge the future trends.
How long does the ASIC design cycle last?
The latter is particularly important because ASIC design cycle may be anywhere between 6 months to 2 years. It is therefore important to foresee and predict what trends would be relevant 1-2 years down the line if one needs to sell their product to a wide audience.
How is ASIC used in the real world?
Analog Design: In addition to digital logic, ASIC may have many analog components help in interfacing with the real world and may comprise of Temperature Sensors, Analog to Digital (ADC) and Digital to Analog Converters (DAC), and most importantly the clock generating unit the Phase Locked Loops (PLLs).
When does partitioning take place in an ASIC design?
7. Partitioning of a large design into a small ASIC design takes place. This is done mainly to separate different functional blocks and also to make placement and routing easier.
