Let's Program the Transistors
The chip design includes different types of processing steps to finish the entire flow. For each and every step, the design process requires a dedicated EDA tool. These tools have the flexibility to import or export different types of files. The picture below shows the various steps of the design flow: Here is a brief…
Fault tolerance of electronic system is a major concern for the VLSI engineers. This can be realized from the post Need of Fault Tolerant VLSI System Design. The objective of this post is to introduce the proper tools for fault tolerance measure. A measure is a mathematical abstraction, which expresses only some subset of the object’s…
In Electronics industry incorrectness in products are described in several ways which may create confusion in understanding the terms defect, error and fault. Though these terms are used interchangeably in the field of VLSI testing, let’s try to draw a fine boundary between the meaning of these terms. Before doing this, we should understand why…
In the previous post we have understood the need of Fault Tolerance in VLSI System Design. A VLSI system can broadly be considered as a union of following 3 layers: Designers introduce several techniques to all these system layers to deal with transient as well as permanent faults, and these techniques incorporate the concept of…
As briefly discussed in our previous article, device driver is a software that is used to control a hardware device and make it work. It acts as an interface between the user-application and the hardware. Any user-application reaches out to the device driver for any interaction with the hardware device and the device driver checks…
In recent few years VLSI design has achieved remarkable growth. High performance (peta-scale) computing is a reality now and we are expecting exa-scale computing by 2020. We talk about many core processor now a days. Intel’s Xeon Phi (Knights Landing) with 72 cores and IBM’s Kilocore processors with more than 1000 cores are great examples…
Device driver is a computer program that controls a particular device that is connected to the system be it printers, CD-ROM readers etc. Before we go into device drivers, let us get a brief of the Linux architecture. The Linux virtual memory is divided into two partitions namely user space and kernel space to protect…
This is an interview experience of Qualcomm, an American multinational semiconductor and telecommunications equipment company. This is an on campus placement experience and has been share by Mr. Ishaind Gupta (IIIT Delhi). As we all know that in this every second changing world a smart phone plays a very big role. A smartphone enables a…

This post is about characterizing or calculating pin average toggling power for any on chip module, using SPICE simulations, Toggling power or Dynamic power is the power dissipated during the transition of any input signal from low to high or high to low. During this time certain amount of current is drawn from the supply…

Cypress Semiconductor Interview Question Bank continued from Part 1… Q : What is LFSR? Name some industry applications of it. A : LFSR stands for Linear Feedback Shift Register in which the input bit is driven by a linear function of overall value of the shift register. In industry, it finds applications in encryption and decryption…
