Signal Electromigration (Signal EM): Violations, Examples, and Practical Fixes

  Hello Dear Readers,   Today in this post, I will provide some deep insight into the Signal Electromigration (Signal EM): Violations, Examples, and Practical Fixes. 1. Introduction: As technology nodes shrink into the deep‑submicron and nanometer regime (7nm, 5nm, 3nm and beyond), electromigration (EM) has become a first‑order reliability concern—not only for power/ground (PG) networks but also for signal nets. Signal EM failures are often underestimated because signal currents are transient and bidirectional. However, with higher switching activity, tighter metal pitches, thinner wires, and aggressive timing closure, signal EM can cause latent or early‑life failures if not addressed properly. This article explains: What Signal EM is and how it differs from PG EM Typical Signal EM violation scenarios Detailed, practical examples Root causes behind each violation Proven solutions and best practices to fix and prevent Signal EM issues 2. What is Signal Electromigration: El...

RTL Lead Design Engineer at Cadence Design System

 Hello Dear Readers,

Currently, at Cadence Banglore vacancy for the RTL Lead Design Engineer role.

Position Description:


  • RTL Design Engineer for DDR Memory Controller IP development team.
  • Position is based in Bangalore.
  • The role would include design and support of the RTL of the DDR Memory Controller solution of Cadence.
  • All leading DDR memory protocols will be supported – including DDR4/LPDDR4.
  • The work involved will be working with the existing RTL, addition of new features into the RTL, ensuring various customer configurations are clean as part of verification regressions, supporting customers, ensuring design is clean for LINT and CDC design guidelines.

Position Requirements:

  • BE/B.Tech/ME/M.Tech - Electrical / Electronics / VLSI with an experience as a design and verification engineer, with a large portion of the recent work experience on RTL design and development.
  • RTL Design using Verilog is a must.
  • System Verilog experience and experience with UVM-based environment usage / debugging are required.
  • AXI3/4 experience is a desired.
  • DDR Memory controller and protocol experience are highly desirable. Prior experience in RTL design and implementation of complex protocols is a must.
  • Prior experience in IP development teams would be an added advantage.

Exploring the Role of LEF Files in VLSI Chip Design: A Beginner's Guide

Hello Dear Readers,   Today in this post, I will provide some deep insight into the LEF file role during the VLSI Chip Design process. In VLSI (Very Large Scale Integration) design, a LEF file is a file that contains information about the physical geometry of the standard cells used in a circuit. LEF stands for Library Exchange Format. A standard cell is a pre-designed logic cell that contains a specific function, such as a flip-flop or an AND gate. Standard cells are designed to be easily combinable and scalable to create more complex circuits. The physical geometry of each standard cell is defined in the LEF file. The LEF file contains information such as the width, height, and position of the pins and metal layers of each standard cell. It also contains information about the physical design rules that govern the placement of these cells on the chip. LEF files are important in VLSI design because they enable the interoperability of different design tools from different vend...

Best Book for Designing Microarchitecture of Microprocessor Using Verilog HDL

  Hello Dear Readers, Currently, after succeeding in many topics now I starting to provide technical book reviews which were I have completed and still read books always. So let us start today's book review. Book Name:   Computer Principles and Design in Verilog  HDL Description:  Uses Verilog HDL to illustrate computer architecture and microprocessor design, allowing readers to readily simulate and adjust the operation of each design, and thus build industrially relevant skills Introduces the computer principles, computer design, and how to use Verilog HDL (Hardware Description Language) to implement the design Provides the skills for designing processor/arithmetic/cpu chips, including the unique application of Verilog HDL material for CPU (central processing unit) implementation Despite the many books on Verilog and computer architecture and microprocessor design, few, if any, use Verilog as a key tool in helping a student to understand these design techniques...
