VSD - Circuit Design & SPICE Simulations

So, you are a professional in VLSI, doing tons of tapeouts and accurate timing analysis.

OR, say, you are a student, who already went through my previous courses on clock tree synthesis, physical design flow and crosstalk,

But, sit back, and give it a thought "Have you done it all?" "Did you know, where does the delay of a cell actually comes from?" "We have learnt about delay models, but are the models accurate?" "How do you verify, if what you are doing in static timing analysis, is correct?" and many more.

These are some of curious questions we wonder about, but hardly find any answers. Even if we found the answers, as a passionate learner, we are still more curious to do some practical things on our own.

And, here's the answer to all of them. SPICE (Simulation Program for Integrated Circuit Emphasis). This course has answers to almost all questions that you might have as a serious timing analyst

So let's get started and keep those questions coming in the forum, and I will answer all of them.

Reviews summary

Circuit design and spice simulation foundation

According to learners, this course provides a solid foundation and deep understanding of MOSFET physics and SPICE simulations, particularly beneficial for those in VLSI or chip design. Students highlight the detailed explanations, the instructor's clear teaching style, and the practical application of concepts. While some found the initial pace slow or the prerequisites high, the majority felt it was a highly valuable and informative course that builds essential skills for analyzing circuit behavior and verifying timing analysis tools.

Course is Part 1, building blocks for next steps.

"This course is clearly designed as the first part of a series. It covers the essential basics before moving to more complex topics."

"Looking forward to the next parts of the series to build upon this fundamental knowledge."

"It provides the necessary foundation to understand subsequent courses on related VLSI topics."

Instructor explains complex topics clearly and effectively.

"The instructor has a knack for explaining complex concepts in a very clear and structured manner. Easy to follow along."

"Lectures break down intimidating topics like drift current and velocity saturation into understandable segments."

"I appreciated the step-by-step approach to deriving equations and explaining the 'why' behind circuit behavior."

Dives deep into technical details required for VLSI.

"This course isn't afraid to go into the technical details needed for serious VLSI work. It's not just a surface-level overview."

"Understanding the physics of short channel effects and velocity saturation is crucial, and this course covers it well."

"The level of detail provided is excellent for anyone serious about circuit design or timing analysis at a foundational level."

Teaches practical SPICE simulation techniques.

"Learning how to set up SPICE decks for different technology nodes was directly applicable to my work."

"The simulations demonstrated in the course helped me see the theory in action and understand how models behave."

"I can now run my own SPICE simulations to test circuits and verify timing analysis results."

Covers core MOSFET physics and SPICE basics well.

"This course provides a solid foundation in MOSFET physics and how it relates to SPICE simulations. Very well explained."

"I found the explanation of NMOS and PMOS behavior and models particularly insightful. It clarified many doubts I had."

"Going deep into the physics behind the models used in SPICE is exactly what I needed to improve my understanding."

Some found the beginning slow; prerequisites might be high.

"While the content is valuable, the initial few modules felt a bit slow-paced for someone with some prior knowledge."

"I think this course assumes some prior background in semiconductors or VLSI, which might make it challenging for absolute beginners."

"Could potentially benefit from a more explicit statement about the ideal background for learners."
