Electromigration and IR Drop Analysis has a New Entrant

Electromigration and IR Drop Analysis has a New Entrant

mPower capacity

My first IR drop analysis was back in the early 1980s at Intel, where I had to manually model the parasitics of the VDD and VSS interconnect for all of the IO cells that our team was designing in a graphics chip, then I ran that netlist in a SPICE simulator using transient analysis, measuring the bounce in VSS and droop in VDD levels as all… Read More


Verification IP vs Testbench

Verification IP vs Testbench

Silicon Maven SemiWiki

Anyone can create a testbench[TB] and verify the design, but it can’t be simply reused as a verification IP [VIP]. So I would like to address in this article: What is VIP? How can we build a high-quality VIP? How can we verify the VIP? What else can we do to make the VIP unique and commercially more valuable?

Most of the module/IP level … Read More

VisualSim example

I’ve simulated IC designs at the transistor-level with SPICE, gate-level, RTL with Verilog, and even used cycle-based functional simulators. Sure, they each worked well, but only for the domain and purpose they were designed for. Industry analyst, Gary Smith predicted that the IC world would soon move to system-level… Read More

PUFiot Supporting Secure Applications

In June 2021, eMemory Technology hosted a webinar titled “PUFiot: A PUFrt-based Secure Coprocessor.” You can read a blog leading up to that webinar here. PUFiot is a novel high-security crypto coprocessor. You can access a recording of that entire webinar from eMemory’s Resources page. While the focus of that webinar was to present… Read More


The Journey of DRAM Continues

The Journey of DRAM Continues
by Arabinda Das on 09-26-2021 at 10:00 am

HBM

The field of DRAM is fascinating as it continues to grow and innovate. For the past ten years, I have often read that DRAM is running out of steam because of its difficulty to scale the capacitor, and yet it continues to evolve since invented by Dr. R. Dennard at IBM. In 1966, he introduced the concept of a transistor memory cell consisting… Read More

Auto Shows Return in Spite of COVID

I knew something special was going on in Munich last week at IAA Mobility – the first international auto show to be held outside China since the start of the pandemic – when a senior executive stepped off the stage before his talk to a modest crowd to say to me (sitting in the second row): “What are you doing here?” I don’t remember whether… Read More

Galileo min

Science texts like to present the evolution of knowledge as step-function transitions, from ignorance to wisdom. We used to think the sun revolved around the earth. Then Galileo appeared, and we instantly realized that the earth revolves around the sun. But reality is always messier, as Galileo understood all too well. The transition… Read More
