Let's Program the Transistors
Binary coded decimal (BCD) is a way to express each of the decimal digits with a binary code. This means that each decimal digit, 0 through 9, is represented by a binary code of four bits. Eg: 98 => 10011000 Unpacking the BCD number is separating each BCD digit. Eg: 98 can be separated as 09…

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. Anuj Kumar (BITS Pilani). Hey guys… I appeared for Qualcomm Interview from Bits-Pilani, Pilani campus. It was 2 day process which included: Written Test Written test included…
8085 is a very basic microprocessor with the capability of limited arithmetic and logical operations. It has dedicated arithmetic instructions for addition, subtraction, increment and decrement. If we want to perform a multiplication operation then we need to write a program for it. Multiplication is nothing but repeated addition. This post presents assembly language program…
The Electronics engineers should know the steps to design a particular circuit. While we study, we directly study the properties of the electronic block and the circuit diagram of the corresponding block. We never think how had we landed up to that particular circuit diagram. For example when we talk about digital Multiplexer, Decoder or Counters; we…

The Synopsys University Program announces the 2016 student design contest in India featuring Synopsys Custom Design tools. This contest gives students the opportunity to showcase their talent in electronic design. Teams selected to compete in the contest will receive a free 3-day training workshop hosted by Synopsys and the chance to win a cash prize….
Mentor Graphics Corporation founded the Higher Education Program in 1985 to further the development of skilled engineers within the electronics industry. The program provides colleges and universities with leading edge design tools for classroom instruction and academic research to help ensure that engineering graduates enter into industry proficient with state-of-the-art tools and techniques. “Verification of…
Syntax: #delay It delays execution for a specific amount of time, ‘delay’. There are two types of delay assignments in Verilog: Delayed assignment: #Δt variable = expression; // “expression” gets evaluated after the time delay Δt and assigned to the “variable” immediately Intra-assignment delay: variable = #Δt expression; // “expression” gets evaluated at time 0 but gets assigned to the “variable”…
There are two basic types of digital design methodologies: top-down Design Methodology In a top-down design methodology, we define the top-level block and identify the sub-blocks necessary to build the top-level block. We further subdivide the sub-blocks until we come to leaf cells, which are the cells that cannot further be divided. bottom-up Design Methodology…
“There is Plenty of Room at the Bottom“ A popular talk delivered by Richard Feynman to American Physical Society at California Institute of Technology in the year of 1959. This talk at that time could foresee the possibility of the revolution which has been brought by VLSI today. The term VLSI stands for Very Large…
Port mapping in module instantiation can be done in two different ways: In this post, we would take one example to understand both types of port mapping in detail. The above Figure shows an example for module instantiation. Figure shows module “SYNCHRO” which consists of 2 ‘D’ flip-flops and are connected in serial fashion. Module “SYNCHRO”…
