This section covers a series of VLSI tutorials and projects.
In today's digital world, electronic circuits play an important role in the devices that we use daily. All the Integrated Circuits ranging from basic IC’s (OR gate, AND gate, NOT gate, Flip Flops, Latches, Counters, ALU’s) to complex circuits like Microprocessor, FPGA, Microcontrollers, SOC, Motherboards are designed by combining billions and billions of transistors in…
If you had gone down to a nearby laptop store for purchasing one, you would have come across the terms “DDR4 DDR3”. For those who are unfamiliar with "DDR4 DDR3", these are different versions of RAM (Random Access Memory). We users always look for better versions of RAM such that there is a seamless performance by the system. Guess what, in this tutorial we are going to…
FSM (Finite State Machines) is a simple state machine or a mathematical model of computation. Each FSM has a finite number of states, inputs, outputs, and rules to change from one state to the other state. FSM is defined by a finite number of states and switches from one state to the other when specific input is given to the state machine. FSM’s are widely used in vending machines,…
Registers are common electronic components that are used in devices to store data. These are the smallest data holding elements which store the operands or instructions that are being processed by the CPU. There are different types of Registers, namely Instruction Registers, Program Registers, ALU Registers, General Purpose Registers, and so on. They differ in the number of bits that can be…
The moment we are asked to do big calculations, we reach out to the calculators to find the answers. But do we know how calculators perform the operations? The calculators have integrated chips that take care of the operations and give us the results. Adders and Subtractors are the basic elements of any ALU’s/Calculating Devices in this modern electronics world. In this…
As a human, if you were asked to select your favourite food or favourite car, how would you compare your choices and conclude an answer? Of course, the answer for the above varies from person to person depending upon their personal preferences and the result will depend on individual choices. It’s a cardinal aspect of our life but the main picture here is that we humans have…
Ever thought of designing your own IC for a specific boolean logic application? Say you want to design an IC where it dispenses Tea, Coffee, Milk-based on the input choice given in an automated cafeteria or you want to actuate mechanical components/light/tasks depending upon the conditions. Boolean logic plays a major role in our day-to-day life. Well, boolean…
Logic gates are the essential building blocks of digital circuits. These basic logic gates are used in Embedded Systems, Microcontrollers, Microprocessors, etc. Let us learn how to design the logic gates using VHDL in ModelSim. This tutorial is all about designing the basic logic gates using different VHDL modeling and their…
