A System on Chip (SOC) is nothing but an integrated circuit (IC) with a full-proof system or a complete computer on a single platform chip. The SOC design may be followed as an IP-based design or a platform-based design. SOC definition and its Need System on chip (SOC), is an integrated circuit where all the functional elements such as dedicated hardware, processor, memory, I/O, and peripherals are embedded onto a single platform chip to meet the product design requirements. Need for SOC design 1. With the advancement in the technology, it
VLSI systems second sem study material VLSI Design by VLSI Universe - July 2, 2021July 20, 20210 The study material for VLSI System second semester is listed here. Important subjects like VLSI Testing and Design of ASICS will be covered this semester. This semester becomes very crucial for the student as he has to prepare for interviews also and a regular curriculum also. Also if the candidate has got less CGPA in the first semester then he has to cover up here. Along with the second-semester candidate also have to revise first semester subjects like analog, digital, Verilog, and basics of VLSI. Compared to the second semester the first semester will be a bit short in time and the first semester gets over as soon as the student gets set well with the academics. In this article, I will

IP Design in VLSI Process Standard 2021 VLSI Design by VLSI Universe - June 19, 2021July 21, 20210 In the modern semiconductor industry IP (Intellectual Property) based VLSI design is trending. This in the Semiconductor industry has become so important to enhance the production of VLSI chips. These designs are largely reusable in terms of logic function and design layout. It with Verification capability is termed as VIPs. In this article, we will try to understand the design life cycle in VLSI chip design. A semiconductor intellectual property (IP) core is most widely used by the VLSI Chip Design engineers in their own product designs, It has various aspects, In VLSI the IP is produced or being used based on the role of the design engineer. Let us understand why we need IP in VLSI, its brief history, what are the
Power Calculation and Planning in Physical Design of a VLSI chip VLSI Design by VLSI Universe - June 2, 2021July 21, 20210 Power calculation and planning before any signal routing in the VLSI chip physical design is very important. As Power supply rails carry large transient currents which may distort the signal lines using electrostatic discharge if design rules are not met correctly. Introduction to power planning A VLSI chip in the semiconductor industry is intended to perform a specific operation and has to communicate with the outside world through various signals. To have this signal flow to the chip and out of the chip we need a power supply. Hence proper power planning became an essential part of the planning process in the back-end of the VLSI chip design. An appropriate power supply network must be constructed by considering many aspects such as design
Basics of Memory Testing in VLSI Memory BIST VLSI Design by VLSI Universe - May 30, 2021July 21, 20210 Memory is a very important component in the VLSI Semiconductor industry. In VLSI Circuits' memories play a key role in storing huge data. Memory testing in VLSI using Algorithms and Patterns efficiently is important. Built-in self test, self diagnosis, redundancy analysis and self repair. Various test algorithms which helps in testing of memories such as BIST compiler and BIST for RAM in Seconds. Memory faults and basics of checkerboard algorithm and march tests or algorithm will be discussed. Introduction to Memory Testing In the current situation the world is producing large amount of data which needs to stored in the memories. So memory technology is a growing technology in the semiconductor market. Understanding and improving the memory testing in VLSI is very important
Basics of DFT in VLSI Scan Design and DFMA VLSI Design by VLSI Universe - May 29, 2021July 21, 20210 Let us talk about DFT in VLSI that is, Scan Design for Testing or Design for Testability and it is not Discrete Fourier Transform from Mathematics. Here the main purpose of the DFT Engineers in VLSI is to incorporate some extra logic structure in the design to make the testing easy, cost effective and efficient design for manufacturing and assembly (DFMA). Mainly here we are going to add some DFT testability features to design of a hardware product. After going through this post completely we must be able to answer all the following questions and the same these questions can be asked in VLSI interview. What is DFT in VLSI? Why DFT is used in VLSI? Why DFT is required? What is DFT architecture? What is
Complete ASIC Design flow 2021 VLSI Design by VLSI Universe - May 4, 2020July 21, 20210 This is the standard VLSI design flow that every semiconductor company follows. The complete ASIC design flow is explained by considering each and every stage. Specification Let us assume we all are IC design engineers, So you are getting the specification from the customer say to design a full adder. For example, the customer says to design a Full adder with 2GHz or 5GHz frequency. So the specification is the first stage in any ASIC design. The specification may be the power or chip area or the chip speed. Microarchitecture design There will be a top-level design engineer in any company that decides the microarchitecture for the specification is whatever given by the customer. He will design the sample architecture which contains for example for a
The difference between latch and flipflop VLSI VLSI Design by VLSI Universe - April 23, 2020July 20, 20210 The difference or the comparison between the latch-based design and the flip-flop-based design is explained briefly. Let us compare the two types of design a Latch-based design and a Flipflop or Register-based design. These also help to understand the advantages and disadvantages of the latch and flip-flop. Latch Flip-flop 1 A Latch is a transparent device and is level-sensitive or pulse-sensitive. Either it can be a positive level triggered or negative level triggered. A flip-flop is also a transparent device, which is made up of a pair of level-sensitive latches, and the flip-flop is edge sensitive. 2 The latch is very less sensitive to the pulse duration i.e. soft barrier. The flip-flop is more sensitive to the pulse transition i.e. hard barrier. 3 The enable pin EN in the latch
