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...

CPU Hardware Architect at Imagination

 Hello Dear Readers,

Currently, Imagination has a vacancy for a CPU Hardware Architect role.

The role is for our fast-growing CPU Hardware team. We are expanding our CPU IP development from internal use to support an extensive portfolio offering highly competitive RISC-V CPUs, either as standalone IPs or as part of Imagination’s Heterogeneous Compute offering, which includes our world-class GPU and NNA compute elements. Our mission is to create through constant innovation the best-in-class RISC-V CPUs for a wide range of market segments and applications.

Reporting to the Vice President of CPU HW Engineering, we are looking for an individual with proven technical leadership and applied knowledge of various Computer and CPU architecture and micro-architecture topics.

The successful candidate will be join our CPU Architecture team which is responsible for defining the CPU micro-architecture, influencing the evolution of the RISC-V ISA and working with customers and ecosystem partners to deliver against the CPU roadmap.

You will:

    • Define the architecture and micro-architecture of Imagination CPUs to implement the required features and achieve power, performance, and area goals
    • Work with the software and hardware product engineering leadership teams to ensure that implementations meet the required goals in the required timeframe
    • Define future roadmap features and performance requirements with the Product Team
    • Work with the CPU Engineering Leadership Team and Imagination Research Team on technology pipelines and the implementation of Imagination’s Heterogenous Compute strategy
    • Liase with customers and ecosystem partners to understand future roadmap requirements
    • Coordinate activities with RISC-V International, participating in workgroups to ensure future ISA decisions are aligned with Imagination requirements
    • Help Imagination establish a leadership position in the wider RISC-V Ecosystem
    • Instigate continuous improvement of processes, and govern the engineering development flow
    • Have a proven track record of significant technical contribution to multiple and complex CPU IP developments
    • Have strong technical knowledge of CPU architecture and micro-architecture, with expert knowledge on at least one architecture domain (CPU Pipeline, CPU Memory System, Coherency, Debug and Trace etc)
    • An understanding of technology requirements for specific CPU applications including mobile, automotive and data center and the ability to translate them to product and technical requirements
    • Have strong leadership skills with the ability to influence stakeholders and inspire the engineering team
    • Be able to demonstrate effective critical analysis and proven decision-making skills, with the capability to present complex ideas in simple terms
    • Have significant experience in working and technically driving engineering teams in a global, multi-location environment
    • Be able to operate in a dynamic environment and help set the technical direction of the engineering team
    • Be able to demonstrate significant expertise in IP Design and/or Verification methodology

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...
