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 Design Engineer at OpenFive

 Hello Dear Readers,

Currently, at OpenFive vacancy for RTL Design Engineer role.

OpenFive is looking for an individual with strong RTL Design skills. The SOC IP Team is responsible for all in-house soft and hard IPs. As an employee, you will have the opportunity to work on any of the IPs in our portfolio, which are as follows:

  •  100G/400G Ethernet
  • Memory Controllers and Soft PHYs
  • High Throughput/Low Latency Interlaken Controllers
  • D2D Controllers

We are a team with soft boundaries across teams and it is possible for you to work on one or more of these IPs from time to time. You would also get the opportunity to work on these IPs targeted for the latest tech nodes from different foundries Ex 5nm, 7nm etc. We also tapeout test-chips on a regular basis to prove our IPs in Silicon. This provides an excellent opportunity for you to learn the entire tapeout process and post-silicon validation as well.
Our Team focuses on high-quality of work and strong work ethic! We have a very exciting workplace and look forward to having you on-board.
The job profile involves the following at broad level and depending on the grade you are hired for you will get to work on various aspects of the job profile.
 
Our workplace provides an excellent opportunity to enhance your skill set not only in RTL Design and Verification but an all-round perspective:

  • Understanding of the IP marketplace
  • View into the overall semiconductor industry trends
  • Development of Industry Standard requirements and thus better Design/Verification ethics

 

Responsibilities:

  • Will be given an independent block(s) in an IP to be owned end-to-end which includes Microarch development, RTL design, review of Verification plan and full debug support
  • Required to support Emulation activities as well
  • Will need to guide juniors technically.
  • Interface with customers on various deliverables

Requirements:

  • Minimum 2 years of experience in RTL Design
  • Candidate must have Worked on RTL design of major blocks
  • Worked on micro-arch of major blocks
  • Strong knowledge in Design (Verilog) and verification aspects of design
  • Experienced at least one complete delivery from start to finish
  • Good analytical and Debug skills
  • Good knowledge in at least one/two of these protocols
  • HBM or DDR , Ethernet, Interlaken, AMBA
  • Expected to have very deep knowledge/understanding on the blocks that you have worked on

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...
