X-propagation in VLSI refers to the propagation of the ‘X’ value, which represents an unknown logic value, through different logic gates in a VLSI (Very Large Scale Integration) circuit. When a simulator is unable to determine whether a logic value should be a ‘0’ or a ‘1’, it assigns an ‘X’ value. This can lead […]

1. Why PCIe is a serial Protocol? PCIe is a serial protocol because it sends data one bit at a time, as opposed to parallel protocols, which send data multiple bits at a time. There are a number of reasons why PCIe is a serial protocol: Speed: Serial protocols can achieve higher speeds than parallel

Introduction: The queue is a special data type in System Verilog that works on the principle of FIFO (First in First Out). Thus, the element that is stored first in the queue is retrieved first, just as the case in the real-life queue. What is Queue in System Verilog? Concept of push and pop:-

A black-box is a module in which only the input and output ports of module is available for the designers to connect and integrate with the other modules: The below is an example of a 2 to 1 multiplexer black-box module: /////////////—————–////////////////////module mux2_1 (input a,input b,input sel,output reg out); endmodule/////////////////————-///////////////// In the above Verilog code

Design Process: -ASICs are designed from scratch to meet a specific set of requirements, while SoCs are built around an existing processor architecture (X86, ARM, RISC V), and incorporate a combination of pre-designed and custom built components. Configurability: – ASICs can not be reprogrammed, while SOCs can be reprogrammed to add a new functionality or

While CPUs (Central Processing Units) are the most commonly used processors in computers and servers, there are alternative processor architectures and competitors in the market. Here are some notable alternatives: CPU Series:- 1. GPUs (Graphics Processing Units): Graphics cards, or GPUs, are primarily designed for rendering graphics and accelerating video processing. However, their parallel computing capabilities have

Power-on Reset (POR):This reset is activated when power is first applied to the SoC. It ensures that the initial state of the entire system is well-defined and reliable by resetting all the components to a known state. Hard Reset:Also known as a hardware reset or system reset, this type of reset is typically triggered by
What are the different types of resets are there in a typical SoC: Read More »
