What is I2C? I2C (Inter-Integrated Circuit), pronounced I-squared-C, is a synchronous, multi-master, multi-slave, serial communication protocol. It was introduced by Philips (now NXP) in 1982. I2C allows a processor or microcontroller to communicate with multiple peripheral devices using only two wires. Simple Example: A microcontroller communicating with sensors, EEPROMs, RTCs, or displays using just SDA

Introduction In VLSI verification and RTL design, file management is a daily task — moving testbenches, creating backups, cleaning log files, or searching through massive simulation outputs.This tutorial covers essential Linux commands to copy, move, delete, and search files efficiently. 1. Copying Files and Directories – cp To make a copy of a file: Example:
Introduction Before you start working on RTL design or simulation tools like Synopsys VCS, Cadence Xcelium, or Mentor Questa, it’s essential to understand how to navigate Linux directories. Almost all EDA tools are command-line driven, and knowing these commands helps you manage design files efficiently. 1. Listing Files and Directories – ls When you log
