Preface
This tutorial mainly covers some of the knowledge involved when using Verilog for digital IC design (Digital Integrated Circuit Design), with greater emphasis on the safe, stable, and convenient implementation of digital circuits. It is entirely appropriate to understand this tutorial as"Verilog Tutorial"the advanced volume—nothing could be more fitting.
The main contents include: low-level (Chapter 1 Gate-Level Modeling, Chapter 2 User-Defined Primitives UDP, Chapter 9 Logic Synthesis), timing (Chapter 3 Timing Analysis), optimization (Chapter 4 Synchronous and Asynchronous, Chapter 5 Reset and Clock, Chapter 6 Low-Power Design), and techniques (Chapter 7 System Tasks, Chapter 8 Programming Language Interface PLI).
Who this tutorial is for
This tutorial is designed for students who already have some foundation in Verilog and digital circuits.
Before reading this tutorial, please first refer to the basic volume"Verilog Tutorial"。
Cat Me
Basic"Verilog Tutorial"I have received many corrections and inquiries from students, and I have revised and replied to them in my spare time. I am very grateful for the verbal encouragement and support from the many scholars. Due to the limitations of the reply mechanism, I cannot promptly convey the emotion and gratitude in my heart. I also hope that this advanced tutorial can bring further benefit to you, who are hardworking and kind.

The entire tutorial was manually collected, organized, and written by myself. All design simulations are original or improved, and all source code is attached at the end. If you benefit from it, your appreciation or follow will be the most direct and effective support, warming me to gather more fruits of digital design.

A Heartfelt Maxim
I am most averse to those greasy bowls of chicken soup for the soul, but the bone soup brewed by the people's poet "Mu Zhe" does seem quite fragrant. Let me quote it here, written for everyone and also for myself, as mutual encouragement.
At this age, I am still awkwardly chasing the night bus in this city, and yet I still agonize over the price differences between different food delivery merchants. I like weekends yet fear them; laughter and joy are the brief entertainment and relaxation I experience on TV, and after the joy ends, I feel even more keenly the city's coldness and loneliness. Full-fledged wings are the blind confidence of the ivory tower; ignorance of the world is the cruel reality of life. Having left my hometown and wandered for over ten years, moving between so-called big cities for study and work, I do not fear the physical exhaustion, but rather the lack of spiritual support. Wielding the whip and riding home in glory is every man's lifelong pursuit, and lofty pride and self-importance are the arrogance in every man's bones. But as the years soak through, reality eventually smooths away the edges, and the mundane world buries our dreams.
An encouraging smile, a nod of approval, a helping hand raised, an attentive listening—all of these let me see the self before being tainted by the smoky fires of life, and see those grievances that would not make anyone's heart ache. Staying alive in this world, it suddenly dawns on me that there should also be a greatness in the ordinary. Do not think that you are merely adrift in the sea of life because you are small, and do not think that your future is without light because it seems distant.
From this moment on, try to make up for regrets, try to grasp those inner voices gushing with wisdom, and feel the excitement and emotion from the depths of your soul. When you are a little better than others, they will be jealous; when you are much better than others, they will only admire you; and when, with a worse foundation and harsher conditions than others, you make it impossible for them to surpass you, they can only worship you. It is a cliché: believe in yourself. Because of life, you are life! Because of miracles, you are a miracle!
