celebrating fall with fletcher's checksum

This post originally appeared on my website.

why are checksums useful for fpga development?

Checksum functions are useful for error detection and data integrity. With respect to FPGA architecture development, a checksum can ensure the system is able to retain its state. For example, an FPGA programmed to behave like an AND gate should not start to act like an OR gate due fluctuations in voltage or temperature. Such problems may be caught by computing the checksum of the bitstream before configuring the FPGA, operating the device in the lab, and then extracting the bitstream and re-computing the checksum to ensure it has not changed.

The last two FPGAs that I worked on-with Indiana University's SAIL-IN Lab and the QuickLogic Corporation-used a scan chain configuration interface which lent itself well to bitstream verification via checksum. The scan chain acts like a serial shift register, stringing together all the configuration chain flip-flops in the FPGA fabric. As the bitstream flows through the head of the scan chain, one bit at a time, its checksum may be computed; and later re-computed as it flows out of the tail. For context, imagine a small, thirty-two flop scan chain and the corresponding bitstream, 0xdeadbeef. On the way in, the Fletcher's (32-bit) checksum will be 0xf13b. If the post-configuration checksum does not match, the engineers would know that there is an issue with the FPGA architecture.

Fletcher's checksum also produces check bytes (or a "tag"), which can be appended to the end of the original data, such that the new checksum of the data and the check bytes is zero. For the example bitstream 0xdeadbeef, the resulting check bytes are 0xd2f1. And the checksum of 0xdeadbeefd2f1 is 0x0.

fletcher's checksum in systemverilog

Based mostly on the Wikipedia entry for Fletcher's checksum, I produced a parameterized, three-state module which computes the checksum and check bytes of a data stream. The SystemVerilog closesly follows the below psuedo-code. For the Fletcher-32 checksum, data arrives as 16-bit half-words.

Eventually, I'd like to wrap it in a SPI interface and submit it to TinyTapeout, but for now here's the bare RTL. The most up-to-date code is also available on GitHub:

Unlocking the Power of System Verilog Assertions with iSpec.ai

Introduction

Assertions play a pivotal role in hardware verification, both for dynamic (simulation based) verification and formal verification. These assertions, expressed in a specialized language, play a crucial role in ensuring the correctness and reliability of complex digital systems. However, crafting these assertions often requires a deep understanding of both the design under test and the intricacies of the assertion language itself. To simplify this process and empower engineers, Agnisys introduces iSpec.ai, a groundbreaking service that transforms natural English text into SystemVerilog Assertions (SVA) with precision and accuracy.

SystemVerilog Assertions: A Brief Overview

Before exploring iSpec.ai, let's first understand the significance of SystemVerilog Assertions in the verification industry. SVA is essential for engineers, enabling them to formally specify the intended behavior of their designs. By expressing properties and constraints concisely, SVA facilitates rigorous verification, detecting errors early in the design cycle and reducing the risk of costly rework and system failures during deployment. From simple temporal (time based) relationships to complex protocol specifications, SVA empowers engineers to articulate a wide range of design requirements with precision and clarity.

Approaching the Challenge: iSpec.ai

At Agnisys, our mission is to democratize the process of generating SVA, making it accessible to engineers of all backgrounds. We are marching towards our stated vision of automatically creating hardware design directly from specifications. With iSpec.ai, assertions can be easily created from natural language specification, bridging the gap between a natural language and hardware verification.

To achieve this ambitious goal, we leverage state-of-the-art Large Language Models (LLM), renowned for their exceptional ability to understand and map dependencies between input and output sequences. Harnessing the power of machine translation, iSpec.ai transforms English specifications into SVA. In developing iSpec.ai, we have adopted a hybrid approach, combining the principles of prompt engineering and fine-tuning LLMs for downstream tasks. This strategic fusion allows us to leverage the strengths of both methodologies, resulting in a service that excels in generating high-quality assertions tailored to the unique requirements of each user.

Understanding Large Language Models

At the heart of iSpec.ai lies the concept of (LLMs), representing a significant advancement in natural language processing. Built upon transformer architectures, these models possess the remarkable ability to understand and generate human-like text across various languages and domains. Central to the efficacy of LLMs is self-attention, a mechanism that enables the model to weigh the significance of different words in a sentence while generating its output. By attending to relevant context and dependencies within the input sequence, self-attention empowers LLMs to capture intricate patterns and semantics, facilitating accurate and contextually relevant text generation.

Fine-Tuning for Downstream Tasks

While pre-trained LLMs exhibit impressive capabilities out-of-the-box, fine-tuning allows us to tailor these models to specific downstream tasks, such as generating SVA. However, traditional fine-tuning approaches pose significant challenges, particularly in terms of memory and compute requirements.

Historically, Full Fine-Tuning has been the predominant method, involving the updating of all model weights during the fine-tuning process. This approach, while effective, demands substantial computational resources, making it impractical for training and deployment on consumer hardware.

Enter Parameter-Efficient Fine-Tuning (PEFT) techniques, a paradigm shift in model adaptation. One such technique, QLORA, has emerged as a game-changer, offering a scalable and memory-efficient solution for fine-tuning LLMs. Quantization reduces computational and memory costs by representing model parameters with lower-precision data types. By employing techniques such as 8-bit integer quantization, QLORA achieves significant compression without compromising model performance.

Complementing quantization, Low-Rank Adaptation (LORA) targets the reduction of trainable parameters by selecting lower-rank matrices within the model architecture. By freezing pretrained weights and adapting only a subset of parameters, LORA minimizes memory overhead while preserving the expressive power of the underlying LLM. In essence, QLORA enables efficient fine-tuning of LLMs on consumer hardware, overcoming the barriers associated with traditional approaches and unlocking new possibilities for downstream applications such as iSpec.ai.

Addressing Challenges and the Path Forward

Despite the remarkable capabilities of iSpec.ai in SVA generation, challenges persist, particularly regarding data availability for fine-tuning. Accessing high-quality training data for niche domains like hardware verification remains a hurdle. Recognizing this, iSpec.ai is a work in progress, continuously evolving with each iteration. We're committed to refining our dataset and improving accuracy through iterative development and collaboration with experts. By leveraging feedback and advancements in machine learning, we aim to overcome these challenges and push the boundaries of automated assertion synthesis. Join us in shaping the future of iSpec.ai. With your input, we'll continue to set new standards in assertion generation, empowering engineers with efficient and reliable verification processes.

Conclusion

With iSpec.ai, Agnisys redefines the landscape of SVA generation, offering engineers a transformative solution powered by state-of-the-art machine learning techniques. By seamlessly translating English specifications into precise assertions, iSpec.ai empowers engineers to accelerate the verification process and enhance the reliability of their designs. Leveraging the synergy of large language models, fine-tuning methodologies, and parameter-efficient techniques like QLORA, iSpec.ai stands as a testament to innovation in hardware verification, paving the way for a future where complex assertions are as accessible as plain English.

Açık kaynak GPU:FuryGPU

Açık kaynaklı, tamamen özel bir GPU, dört yıllık geliştirme sürecinin ardından gizlilikten çıktı. FuryGPU , bu son derece karmaşık donanım ve yazılım projesini boş zamanlarında bir araya getirdiğini söyleyen oyun yazılımı geliştiricisi Dylan Barrie'nin tek kişilik bir çabasıydı. FuryGPU, Xilinx FPGA tasarımını temel alıyor ve prototip PCIe grafik kartı şu anda Quake Timedemo'da yaklaşık 44 fps hıza ulaşma kapasitesine sahip. FuryGPU üzerindeki çalışma, Barrie'nin Ben Eater'ın sıfırdan programlanabilir 8 bit bilgisayar oluşturma projesinden ilham almasıyla gerçekleştirildi . FuryGPU, DisplayPort ve HDMI çıkışlarıyla donatılarak modernize edilmiş, yaklaşık 20 yıl önceki tipik bir PC grafik kartına çok benziyor. Ancak proje donanımdan çok daha fazlası; Barrie, bu grafik kartının tasarımının en acı verici yönünün Windows sürücülerini oluşturmak olduğunu itiraf ediyor. Barrie, FPGA paketli Arty Z7 geliştirme kartını alıp bazı ön geliştirme ve testler yaptıktan sonra sıfırdan bir GPU oluşturma hayallerini gerçekleştirmeye başladı. Daha sonra proje, "inanılmaz derecede ucuz Zynq UltraScale+ FPGA'leri bir ton DSP birimi ve (nispeten) büyük miktarda LUT ve FF ile birleştiren Xilinx Kria Modüller Üzerinde Sistem'in (SoM'ler) piyasaya sürülmesiyle hız kazandı. Özellikle ilgi çekici olan, güçlendirilmiş PCIe çekirdeğidir," diye heyecanla dile getirdi Barrie. Bu üretici karttan 2024'te gördüğümüz FuryGPU PCIe eklenti kart tasarımına geçmek için Barrie, SystemVerilog donanım açıklamasını ve donanım doğrulama dilini ve KiCAD EDA / elektronik CAD yazılım paketini kendi kendine öğrendi. SoM'de yerleşik FPGA devresi olsa bile, bugün gördüğümüz 4 şeritli PCIe ile FuryGPU'nun şemasını tasarlamak için Herkül gibi bir çaba gerektiğini söylüyor. Artık FuryGPU'yu test donanımına takma, sürücüleri yazma ve oyunları test etme zamanı gelmişti. https://www.youtube.com/watch?v=VJigQ2Rm-TQ&embeds_referring_euri=httpswww.tomshardware.com&source_ve_path=MjM4NTE&feature=emb_title FuryGPU için Windows sürücülerini oluşturmak, Barrie tarafından tüm projenin "en acı verici" yönü olarak tanımlanıyor; günlük işi son 14 yıldır oyun geliştirme endüstrisinde grafik oluşturmanın yazılım tarafında olmasına rağmen. Başlangıçta FuryGPU üreticisinin amacı, GPU'nun çalıştığını göstermek için basit bir dönen küp demosu oluşturmaktı. Ancak proje geliştikçe ikonik PC oyunu Quake'i oynanabilir kare hızlarında oynamak yeni hedef olmaya başladı. Barrie, Windows sürücülerini hazırladıktan sonra, GPU ile iletişim kurmak için özel bir grafik API'si yazdığını, ekran ve ses için Windows çekirdek sürücülerini yazdığını ve artık "Quake'i istediğiniz hızda işleyebilen tam işlevli bir grafik donanımına" sahip olduğunu açıklıyor.

Digital Design: With an Introduction to the Verilog HDL, VHDL, and SystemVerilog 6th Edition, ISBN-13: 978-0134549897 [PDF eBook eTextbook] Publisher: ‎ Pearson; 6th edition (March 7, 2017) Language: ‎ English 720 pages ISBN-10: ‎ 9780134549897 ISBN-13: ‎ 978-0134549897 The speed, density, and complexity of today’s digital devices are made possible by advances in physical processing technology and digital design methodology. Aside from semiconductor technology, the design of leading-edge devices depends critically on hardware description languages (HDLs) and synthesis tools. Three public-domain languages, Verilog, VHDL, and SystemVerilog, all play a role in design flows for today’s digital devices. HDLs, together with fundamental knowledge of digital logic circuits, provide an entry point to the world of digital design for students majoring in computer science, computer engineering, and electrical engineering. In the not-too-distant past, it would be unthinkable for an electrical engineering student to graduate without having used an oscilloscope. Today, the needs of industry demand that undergraduate students become familiar with the use of at least one hardware description language. Their use of an HDL as a student will better prepare them to be productive members of a design team after they graduate. Given the presence of three HDLs in the design arena, we have expanded our presentation of HDLs in Digital Design to treat Verilog and VHDL, and to provide an introduction to SystemVerilog. Our intent is not to require students to learn three, or even two, languages, but to provide the instructor with a choice between Verilog and VHDL while teaching a systematic methodology for design, regardless of the language, and an optional introduction to SystemVerilog. Certainly, Verilog and VHDL are widely used and taught, dominate the design space, and have common underlying concepts supporting combinational and sequential logic design, and both are essential to the synthesis of high-density integrated circuits. Our text offers parallel tracks of presentation of both languages, but allows concentration on a single language. The level of treatment of Verilog and VHDL is essentially equal, without emphasizing one language over the other. A language-neutral presentation of digital design is a – common thread through the treatment of both languages. A large set of problems, which are stated in language-neutral terms, at the end of each chapter can be worked with either Verilog or VHDL. The emphasis in our presentation is on digital design, with HDLs in a supporting role. Consequently, we present only those details of Verilog, VHDL, and SystemVerilog that are needed to support our treatment of an introduction to digital design. Moreover, although we present examples using each language, we identify and segregate the treatment of topics and examples so that the instructor can choose a path of presentation for a single language—either Verilog or VHDL. Naturally, a path that emphasizes Verilog can conclude with SystemVerilog, but it can be skipped without compromising the objectives. The introduction to SystemVerilog is selective—we present only topics and examples that are extensions of Verilog, and well within the scope of an introductory treatment. To be clear, we are not advocating simultaneous presentation of the languages. The instructor can choose either Verilog/SystemVerilog or VHDL as the core language supporting an introductory course in digital design. Regardless of the language, our focus is on digital design. The language-based examples throughout the book are not just about the details of an HDL. We emphasize and demonstrate the modeling and verification of digital circuits having specified behavior. Neither Verilog or VHDL are covered in their entirety. Some details of the languages will be left to the reader’s continuing education and use of web resources. Regardless of language, our examples introduce a design methodology based on the concept of computer-aided modeling of digital systems by means of a mainstream, IEEE-standardized, hardware description language. This revision of Digital Design begins each chapter with a statement of its objectives. Problems at the end of each chapter are combined with inchapter examples, and with in-chapter Practice Exercises. Together, these encounters with the subject matter bring the student closer to achieving the stated objectives and becoming skilled in digital design. Answers are given to selected problems at the end of each chapter. A Solution Manual gives detailed solutions to all of the problems at the end of the chapters. The level of detail of the solutions is such that an instructor can use individual problems to support classroom instruction.

An Introduction to SystemVerilog: Overview and Benefits

Are you looking to get up to speed with the basics of SystemVerilog? This introduction will provide a comprehensive overview of SystemVerilog and all its benefits. SystemVerilog is an incredibly powerful programming language and hardware description language (HDL) used for the verification, design, synthesis, emulation, and prototyping of digital circuits.

The language enables users to efficiently create intricate designs that can be tested quickly and accurately for verification purposes, as well as optimized for cost reduction when transferred into silicon.

Regardless of your previous experience level or coding expertise, this guide provides all the essentials needed to understand why so many people are drawn towards using SystemVerilog in their projects.

What is SystemVerilog?

SystemVerilog is an extension of Verilog, which was developed by Accellera to enhance the design, verification, and synthesis of digital circuits and systems. This language provides object-oriented programming features, constrained random testing, assertions, and coverage analysis. It has become a popular language for both design and verification of digital systems, due to its flexibility and functionality.

Evolution of Verilog to SystemVerilog

Verilog was enhanced to SystemVerilog to address the growing complexity of digital circuits and systems. SystemVerilog added features such as object-oriented programming, constrained random testing, assertions, and coverage analysis to improve design verification, modeling, and synthesis.

Features and capabilities of SystemVerilog

Some of the notable features and capabilities of SystemVerilog include:

Object-oriented programming (OOP) features, such as classes, objects, and inheritance, enable modular and reusable design structures.

Constrained random testing (CRT) allows designers to create random input stimulus while constraining the values to ensure proper functionality and performance.

Assertions and coverage analysis enable designers to check the correctness of their designs and ensure that they meet the desired functional and performance requirements.

Design hierarchy and interface modeling enable designers to organize and manage complex designs with multiple modules and interfaces.

Design reuse and system-on-chip (SoC) design capabilities facilitate the creation of complex designs with pre-designed components and IP blocks.

SystemVerilog also includes features for low-power design, testbench automation, and FPGA synthesis.

Advantages of SystemVerilog

Here are some advantages of SystemVerilog:

SystemVerilog code is more concise and requires fewer lines of code compared to Verilog, which can save time and reduce errors.SystemVerilog includes structures and enumerated types that provide a more scalable and efficient way to design and manage complex digital systems. Interfaces in SystemVerilog provide a higher level of abstraction and enable faster design iterations and easier reuse of IP blocks.SystemVerilog is widely supported in electronic design automation (EDA) tools, including Vivado synthesis, which makes it easy to synthesize and implement designs on FPGAs

SystemVerilog vs. Verilog

Verilog is a Hardware Description Language (HDL) used for modeling and structuring electronic systems, while SystemVerilog combines HDL and Hardware Verification Language (HVL) to facilitate modeling, designing, simulating, testing, and implementing electrical systems.

In Verilog, module-level testing is used for the testbench, while SystemVerilog utilizes class-level test benches for more advanced and efficient testing. While Verilog uses C and Fortran programming languages, SystemVerilog is a programming language that combines Verilog, VHDL, and C++. Verilog supports the datatypes Wire and Reg, whereas SystemVerilog includes enum, union, struct, string, and class datatypes, enabling more versatile modeling and verification capabilities.

In addition to the differences mentioned earlier, Verilog and SystemVerilog also differ in terms of programming paradigms and procedural blocks.

Verilog supports the structured programming paradigm, whereas SystemVerilog supports both structured and object-oriented programming paradigms, enabling more advanced and modular designs.

In Verilog, there is a single always block to implement both combinational and sequential logic. However, SystemVerilog has three procedural blocks, namely always_comb, always_ff, and always_latch, that provide more precise control over logic implementation.

Verilog is based on a hierarchical module design, while SystemVerilog is based on classes that provide more sophisticated design and verification capabilities.

Conclusion

SystemVerilog is an incredibly powerful and efficient tool for those wishing to develop digital designs quickly and reliably. Its encapsulation of VHDL and Verilog properties in one language makes it a necessary addition to any collection of digital design tools.

The interface options, including the command line, graphical user interface, as well as self-verification facilities will empower users with greater flexibility as well as a sound verification process. With such a comprehensive package, it is no surprise that SystemVerilog has become so popular in the design world.

Digital Design: With an Introduction to the Verilog HDL, VHDL, and SystemVerilog 6th Edition, ISBN-13: 978-0134549897 [PDF eBook eTextbook] Publisher: ‎ Pearson; 6th edition (March 7, 2017) Language: ‎ English 720 pages ISBN-10: ‎ 9780134549897 ISBN-13: ‎ 978-0134549897 The speed, density, and complexity of today’s digital devices are made possible by advances in physical processing technology and digital design methodology. Aside from semiconductor technology, the design of leading-edge devices depends critically on hardware description languages (HDLs) and synthesis tools. Three public-domain languages, Verilog, VHDL, and SystemVerilog, all play a role in design flows for today’s digital devices. HDLs, together with fundamental knowledge of digital logic circuits, provide an entry point to the world of digital design for students majoring in computer science, computer engineering, and electrical engineering. In the not-too-distant past, it would be unthinkable for an electrical engineering student to graduate without having used an oscilloscope. Today, the needs of industry demand that undergraduate students become familiar with the use of at least one hardware description language. Their use of an HDL as a student will better prepare them to be productive members of a design team after they graduate. Given the presence of three HDLs in the design arena, we have expanded our presentation of HDLs in Digital Design to treat Verilog and VHDL, and to provide an introduction to SystemVerilog. Our intent is not to require students to learn three, or even two, languages, but to provide the instructor with a choice between Verilog and VHDL while teaching a systematic methodology for design, regardless of the language, and an optional introduction to SystemVerilog. Certainly, Verilog and VHDL are widely used and taught, dominate the design space, and have common underlying concepts supporting combinational and sequential logic design, and both are essential to the synthesis of high-density integrated circuits. Our text offers parallel tracks of presentation of both languages, but allows concentration on a single language. The level of treatment of Verilog and VHDL is essentially equal, without emphasizing one language over the other. A language-neutral presentation of digital design is a – common thread through the treatment of both languages. A large set of problems, which are stated in language-neutral terms, at the end of each chapter can be worked with either Verilog or VHDL. The emphasis in our presentation is on digital design, with HDLs in a supporting role. Consequently, we present only those details of Verilog, VHDL, and SystemVerilog that are needed to support our treatment of an introduction to digital design. Moreover, although we present examples using each language, we identify and segregate the treatment of topics and examples so that the instructor can choose a path of presentation for a single language—either Verilog or VHDL. Naturally, a path that emphasizes Verilog can conclude with SystemVerilog, but it can be skipped without compromising the objectives. The introduction to SystemVerilog is selective—we present only topics and examples that are extensions of Verilog, and well within the scope of an introductory treatment. To be clear, we are not advocating simultaneous presentation of the languages. The instructor can choose either Verilog/SystemVerilog or VHDL as the core language supporting an introductory course in digital design. Regardless of the language, our focus is on digital design. The language-based examples throughout the book are not just about the details of an HDL. We emphasize and demonstrate the modeling and verification of digital circuits having specified behavior. Neither Verilog or VHDL are covered in their entirety. Some details of the languages will be left to the reader’s continuing education and use of web resources. Regardless of language, our examples introduce a design methodology based on the concept of computer-aided modeling of digital systems by means of a mainstream, IEEE-standardized, hardware description language. This revision of Digital Design begins each chapter with a statement of its objectives. Problems at the end of each chapter are combined with inchapter examples, and with in-chapter Practice Exercises. Together, these encounters with the subject matter bring the student closer to achieving the stated objectives and becoming skilled in digital design. Answers are given to selected problems at the end of each chapter. A Solution Manual gives detailed solutions to all of the problems at the end of the chapters. The level of detail of the solutions is such that an instructor can use individual problems to support classroom instruction.
