What is Gradient Density in VLSI Layout Design?
When you work on a VLSI layout, Gradient density DRC refers to the variation in pattern density across different regions of the chip. It shows how the density…
Crosstalk in VLSI: Understanding Causes and Proven Reduction Techniques
When working with VLSI circuits, one thing you, as a designer, might face is the issue of crosstalk. We all know that as technology scales down, devices become…
What are the Mechanisms of Charge Injection in MOSFETs
Charge injection in MOSFETs occurs through mechanisms such as Hot electron injection and Fowler–Nordheim tunneling, each with distinct behaviors and implications for n-channel and p-channel devices. Hot Electron…
HBM vs. DDR: Key Differences Explained for High-Performance Computing
HBM (High-Bandwidth Memory) and DDR (Double Data Rate) are both types of DRAM, but they serve different purposes and have significant differences. Let’s break it down in simple…
A Beginner’s Guide to Memory Layout in 5nm Technology
When diving into memory layout in 5nm technology, it’s helpful to understand how far we’ve come in SRAM design and the challenges that come with scaling. In this…
What is Drain-Induced Barrier Lowering (DIBL)?
Drain-Induced Barrier Lowering (DIBL) is a phenomenon observed in short-channel MOS transistors. You can think of it as a reduction in the transistor’s threshold voltage caused by the…
Why do We use Dummy Fill in the Layout Design?
When you deal with the etching process, one big challenge comes from regions with different metal densities. Let me give you an example. In older processes, aluminum was…
Optical Proximity Correction: Applications and Challenges
Optical Proximity Correction (OPC) is an important technique we use to fix mistakes that happen during the imaging process in lithography. It involves making changes to the mask…
Top Most Asked Verilog Interview Questions( 2024)
Verilog is a language we use to describe how digital systems work, like network switches, microprocessors, memory, or flip-flops. You can use it to check if analog and…
Electromigration in IC Design: Tips for Reducing EM
Electromigration (EM) is a phenomenon where metal ions in an interconnect get displaced due to the flow of electrons. You need to consider how this affects our circuit…
