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...

Silicon CPU/ SOC Verification Engineer at Rivos Inc

   Hello Dear Readers,

Currently at Rivos Bangalore vacancy for a Silicon CPU/ SOC Verification Engineer role.

Positions are open for full-time and Co-op/internship in the areas of CPU and SOC verification from unit level to chip level as well as all aspects of verification such as functional, microarchitecture, performance, and formal.

We are looking for all levels of talent, from entrance to advanced level of experience.


Responsibilities:

  • Work closely with architecture and RTL designers on verifying the functionality correctness of the design
  • Reviewing Architecture and Design Specifications
  • Develop test plans and test environments
  • Develop tests in assembly, C/C++, or vectors according to test plans
  • Develop coverage monitors and analyze coverage to ensure all the test cases in the plans are covered
  • Develop checkers in SystemVerilog or C-base transactors to verify the design
  • Write assertions and apply formal verification to the designImplementing test benches, generating directed/constrained random tests
  • Debugging failures, running simulations, tracking bugs
  • Handling schedules and supporting multi-functional engineering effortAssisting in verification flows, automation scripts and regressions


Requirements:

  • In-depth knowledge of digital logic design, CPU/SOC architecture and microarchitecture.
  • Sophisticated knowledge of SystemVerilog.
  • Experienced level knowledge C/C++.Relevant knowledge of verification methodologies and tools such as simulators, waveform viewers, build and run automation, coverage collection.
  • Basic knowledge of formal verification methodology is a plus.
  • Excellent knowledge of one of the scripting languages such as Python, TCL is a plus.
  • Excellent skills in problem solving, written and verbal communication, excellent organization skills, and highly self-motivated.
  • Ability to work well in a team and be productive under aggressive schedules.


Education and Experience:

  • PhD, Master’s Degree or Bachelor’s Degree in technical subject area.

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...
