fpga prototyping manualThe manual is organized into chapters which are roughly in the same order as the tasks and decisions which are performed during an FPGA-based prototyping project. The manual can be read start-to-finish or, since the chapters are designed to stand alone, you can start reading at any point that is of current interest to you. This manual is a must-read for anyone designing, or getting ready to design, an SoC. This blog is dedicated to discussing technically challenging ASIC prototyping problems and sharing solutions. Doug gained an honors degree in Electrical and Electronic Engineering from the University of Bath, England in 1980. He did his first programmable logic design in the mid-80’s, when FPGAs were still called Logic Cell Arrays. Since then, Doug has designed or supported countless FPGA and ASIC designs either as an independent consultant or working with the leading vendors. Doug became Synplicity’s first engineer and Technical Director in Europe (Synplicity was acquired by Synopsys in 2008) and has presented widely on FPGA design and FPGA-based prototyping since that time. For the last ten years at Xilinx, Austin was in the IC Design department for the Virtex product line. His new role is working for Xilinx Research Labs, where he is looking beyond the present technology issues. Rene holds an MSEE degree, the Dipl.-Ing. der Elektrotechnik, from the Chemnitz University of Technology in Germany in 1999. He has worked 11 years in the area of FPGA-based Prototyping, first at ISYTEC, then Pro Design and now at Synopsys; each transition as a result of an acquisition. Rene managed the development of the CHIPit hardware platforms before moving on to become Director of Applications. During this time he developed co-simulation interfaces and prototyping hardware and has implemented many ASIC designs in FPGA. Rene has also developed prototyping concepts and solutions for customers and he is one of the inventors of the UMRBus and CHIPit product line.

We start by analyzing the challenges and benefits of FPGA-based Prototyping and how they compare to other prototyping methods. We present the current state of the available FPGA technology and tools and how to get started on a project. The FPMM also compares between home-made and outsourced FPGA platforms and how to analyze which will best meet the needs of a given project. The central chapters deal with implementing an SoC design in FPGA technology including clocking, conversion of memory, partitioning, multiplexing and handling IP amongst many other subjects. The important subject of bringing up the design on the FPGA boards is covered next, including the introduction of the real design into the board, running embedded software upon it in and debugging and iterating in a lab environment. Finally we explore how the FPGA-based Prototype can be linked into other verification methodologies, including RTL simulation and virtual models in SystemC. Along the way, the reader will discover that an adoption of FPGA-based Prototyping from the beginning of a project, and an approach we call Design-for-Prototyping, will greatly increase the success of the prototype and the whole SoC project, especially the embedded software portion. Design-for-Prototyping is introduced and explained and promoted as a manifesto for better SoC design. Readers can approach the subjects from a number of directions.https://www.gloucesterquays.co.uk/images/dynamicImages/hoover-windtunnel-lite-manual.xml Some will be experienced with many of the tasks involved in FPGA-based Prototyping but are looking for new insights and ideas; others will be relatively new to the subject but experienced in other verification methodologies; still others may be project leaders who need to understand if and how the benefits of FPGA-based prototyping apply to their next SoC project. We have tried to make each subject chapter relatively standalone, or where necessary, make numerous forward and backward references between subjects, and provide recaps of certain key subjects.Then you can start reading Kindle books on your smartphone, tablet, or computer - no Kindle device required.

Barbara Girardin 5.0 out of 5 stars A bit dated but very useful for someone wanting to learn about FPGA and it application in prototyping. Book was sent within a god time frame.The organization of the book is not clear to me. Here's an introduction to the FPGA-Based Prototyping Methodology Manual (FPMM), a joint production of Synopsys and Xilinx. David Maliniak 1 Mar 24, 2011 In design automation, methodology counts for a lot. Methodology is, loosely put, how to do things. There are right ways to do things and there are wrong ways. Methodology miscues in EDA flows can end up costing you large sums of money, especially when they are made early in the design process. Conversely, correct methodologies can not only save money but also greatly enhance the making of it. Again, this applies even more so in the earliest stages of the process; decisions made then cost a lot more to correct later if they prove wrong.Methodologies like this are usually a win-win situation.https://formations.fondationmironroyer.com/en/node/15732 The vendors do not produce them strictly out of the goodness of their hearts, of course. Their hope is that with a clearly defined methodology that involves Synopsys tools and Xilinx silicon, designers will be inclined to gravitate toward their products and away from those of other vendors for whose products there is a less clearly delineated methodology. FPGA-based prototyping is becoming a critical aspect of design flows, fueled by the growing complexity of systems and the importance of software as a differentiator. No one can afford to wait until silicon is available to debug software. It has been estimated that in a given system-level design project, there are 100 or more software bugs for every hardware bug. This amplifies the need for a system-level platform for early joint test and debug of how the hardware and software and there is no better way to do this than on FPGAs.Corporate contributors included Freescale Semiconductors, LSI, STMicroelectronics, and Texas Instruments, among others. A 40-member review council oversaw the material.You gain real-time interfaces, cycle-accurate simulation, and high speed. It's a great platform for working out the kinks in a multicore implementation. The prototypes are portable and easily replicated. One is the need for FPGA expertise that may or may not be available. Another is that a given design often must be partitioned across several FPGAs, making it difficult to achieve real-world SoC speeds. Debug is difficult. RTL must be available, and not only that, but the RTL ideally should be optimized for FPGA implementation.That's where a methodology based on proven best practices comes in. Moreover, at larger companies it's not uncommon to find multiple teams engaged in prototyping on the same project. It is incumbent upon them to all use the same platform to avoid waste and encourage reuse.In 500 pages and 15 chapters, the book begins with an introduction to FPGA-based prototyping, moving on to its benefits and currently available tools. From there it moves through the design of a prototyping flow, a treatment of the classic build-vs.-buy decision, and extensive how-to chapters. It concludes with a look at the future of prototyping.This is where Synopsys and Xilinx hope to continue the conversation between prototypers worldwide and to establish a forum for information exchange as well as a repository of best practices going forward. The book is a free download, or printed copies can be purchased through online retailers. Brian Fetz Apr 06, 2016 There is a lot of variety in today’s IoT devices. They may be fairly simple devices, such as sensors transmitting simple data or sensors sending large amounts of data (video for instance). They may be single purpose (measuring temperature) or multipurpose (mobile phones), with substantial subsystems such as GPS, WLAN, Bluetooth, and Cellular. The signal integrity performance of high-speed signals on IoT devices is very susceptible to the battery’s voltage and current performance. Higher rates translate to higher power consumption, and here again engineers will turn to topologies that minimize power. When power is considered as a primary objective, other standard design guidelines are disregarded. The problem is that to get a voltage to a receiver may take 30 to 100 more voltage swing to drive through that back-match resistor. The upshot? Lost power. These are probably the most power-consuming components of all and particularly problematic for engineers. It is possible in some cases, such as USB 3, that receiver errors cause re-transmissions of packets. This reduces the effective data rate, although many times, this isn’t seen because the system is designed to recover. Not specific to new IoT devices, but other signal integrity problems are frequently dropped calls and pixel errors on a TV display. TVs, in fact, are a special case as cable systems are often split multiple times and the operational signal to noise is very, very marginal. This is why power integrity is also becoming more important for IoT validation. In addition, high-speed signals are laid out more densely in IoT devices, resulting in issues such as crosstalk and coupling. RF interference and digital crosstalk mechanisms are common challenges. Alternatively, engineers will need to spend more time validating the interfaces to ensure the high speed signals work correctly at different environmental, temperature and voltage levels. At the very least, that requires modeling the environment and measuring and estimating link budgets for digital systems, crosstalk and so on. Understanding interference effects, link budgets, and so on is critical. And identifying the right tools—testing, probing, and analysis software solutions to quickly identify, quantify and remove cross-talk for analysis and validate designs quickly will be key.

It is one of the bad aspects of being an author in that it becomes impossible, at least for me, to read anything without wanting to mark it up and edit it.She says that there are three laws associated with prototyping: People with more experience may find it possible to skip around various chapters so that they only have to read the sections in which they want to expand their knowledge. It then talks about the types of prototypes that can allow that earlier start as well as other usage models that a prototype enables along with the specific requirements to meets each of those needs. It is a well written chapter and I hope they make this chapter available for everyone so that people not yet familiar with prototyping may get to learn the types of use models and benefits that prototypes can provide. Right here would be a good place for them to make it available! The success stories are told from various companies who have successfully deployed FPGA-based prototyping. The chapter then moves to the general problems associated with mapping SoCs into FPGAs and to ensure that a potential user understands that simulators and prototypes are different. More importantly, it outlines the flow that is to be used during the design and verification flow. It provides a cursory look at how certain kinds of structures are mapped into FPGAs and the mechanisms available to increase visibility and perform debug. This is a dry chapter, but it is all necessary information for those coming at this for the first time. It talks about sizing both from the FPGA and the SoC perspective. Given that everything so far has talked about the Xilinx Virtex 6 family, it was a bit of a surprise to then see Table 8, which says how many Virtex 5s are required for some common IP blocks. I like the fact that the chapter adds a little bit of realism, telling users exactly what to expect in terms of getting the first iteration of a prototype up and running. Since Synopsys has a lot of experience with this, it is hardly surprising that they use many of the design techniques they have employed for their HAPS and ChipIt products as recommendations for users that choose to roll their own. Clearly, when you make your own, you will not need quite the same level of configurability, but there are many useful lessons. It says the unmentionable that at some point changes to the RTL will be necessary. The honesty in this book is actually quite refreshing. It discusses the issues associated with clock gating and memories and tells you which cases will require some manual intervention plus the best practices for maintaining a common set of source files. It also talks about features that just cannot be mapped into a prototype such as some power-saving capabilities being increasingly used in SoCs. For the online version of the book, there is no added expense of using color, and some of the diagrams were created expecting color. So diagrams such as Figure 3 become almost impossible to read in grey-scale because it is impossible to match to the key. In addition, there is no cost to hyper-linking the document such that references are available at the click of a button. This improves general navigation and also makes it possible to dive into topics without losing the general flow.The parts I have read show that the authors do have extensive knowledge and experience of the subject matter and the information is well presented, so this book receives a definite two thumbs up from me!

While the book’s examples refer to Synopsys and Xilinx products, the methodology is applicable to any FPGA-based prototyping project using any tools, boards or FPGAs. Here, we present Chapter Two of the FPMM in its entirety. That is not our intent. The FPGA-Based Prototyping Methodology Manual (FPMM) aims to give a balanced view of the pros and cons of FPGA-based prototyping because we do not want people to embark on a long prototyping project if their aims would be better met by other methods (e.g., a SystemC-based virtual prototype). By staying focused on the aim of the prototype project, we can simplify our decisions regarding platform, IP usage, design porting, debug and other aspects of design. In this way we can learn from the experience others have had in their projects by examining some examples from prototyping teams around the world. It requires a great deal of care and consideration at its different stages. As well as explaining the effort and expertise involved, we should also offer some incentive as to why we should (or maybe should not) perform prototyping during our SoC projects. In many cases, we shall also give examples from the real world and the authors wish to thank in advance those who have offered their own experiences as guides to others in this effort. We put this reason at the top of the list because it is the most likely underlying reason for a team to be prototyping, despite the many given deliverable aims of the project. We could validate the software at even higher performance on a virtual system, but we lose the accuracy that comes from employing real RTL. Running the SoC design at real-time speed connected into the rest of the system allows us to see the immediate effect of real-time conditions, inputs and system feedback as they change. Here, a high-definition (HD) media data stream was routed through a prototype of a processing core and out to an HD display, as shown in the block diagram in Figure 1. Only FPGA-based prototyping allows this real-time dataflow, giving great benefits not only to this type of multimedia application but to many other applications where real-time response to input dataflow is required. However, in many SoC designs it is the software that requires most of the design effort. It is software development and validation that govern the actual completion date when the SoC can usefully reach volume production. In that case, what can system teams do to increase the productivity of software development and validation. To answer this question, we need to see where software teams spend their time. We are all familiar with the software upgrades, service packs and bug fixes in our normal day-to-day use of computers. However, in the case of software embedded in an SoC, this perpetual fine-tuning of software is less easily achieved. Furthermore, embedded software for simpler systems can be kept simple itself and so is easier to fully validate. For example, an SoC controlling a vehicle subsystem or an electronic toy can be fully tested more easily than a smartphone running many apps and processes on a real-time operating system (RTOS). This requires absolute knowledge of the hardware at an address and clock-cycle level of accuracy. Designers of the lowest level of a software stack, often called platform engineers, have the task of describing the hardware in terms that the higher levels of the stack can recognize and reuse.In these lowest levels of the stack, platform engineers and driver developers will need to validate their code on either the real SoC or a fully accurate model of the SoC. Software developers at this level need complete visibility of the behavior of their software at every clock cycle. In a smartphone, these could be a contact manager, a video display, an Internet browser and, of course, the phone subsystem that actually makes calls. Each of these does not have direct access to SoC hardware and is actually somewhat divorced from any consideration of the hardware. The applications rely on software running on lower levels of the stack to communicate with the SoC hardware and the rest of the world on its behalf. More accuracy than necessary will only result in the model running more slowly on the simulator. In effect, SoC modeling at any level requires us to represent the hardware and the stack up to the layer just below the current level to be validated. Optimally, we should work with just enough accuracy to allow maximum performance. In this case, the model need only be accurate enough to fool the application into thinking that it is running on the real SoC; it does not need cycle accuracy or fine-grained visibility of the hardware. However, speed is important because multiple applications will be running concurrently and interfacing with real-world data in many cases. It is possible to use transaction-level simulations, modeled in languages such as SystemC, to create a simulator model that runs with low accuracy but at high enough speed to run many applications together. If handling of real-time, real-world data is not important, then we might be better considering such a virtual prototyping approach. By using FPGAs we can achieve speeds up to real-time and yet still be modeling at a level of full RTL cycle accuracy. This enables the same prototype to be used not only for the accurate models required by low-level software validation but also for the high-speed models needed by the high-level application developers. Indeed, the whole SoC software stack can be modeled on a single FPGA-based prototype. Analyzing the biggest time sinks in its flow, Freescale decided that most benefit would be achieved by accelerating cellular 3G protocol testing. If it could be performed presilicon, the company would save considerable months in a project schedule. Given product lifetimes of only one or two years, this is very significant indeed. Using RTL simulation would take years and even running on a faster emulator would take weeks; neither was a practical solution. FPGAs were chosen because they represented the only way to achieve the necessary clock speed to complete the testing in a timely manner. While the main goal was protocol testing, the use of FPGAs meant that all of these software developments would be accomplished presilicon, greatly accelerating various end-product schedules. The baseband processor included a Freescale StarCore DSP core for modem processing and an ARM926 core for user application processing, plus more than 60 peripherals. In addition, some of the RTL was generated automatically from system-level design code, which can also be fairly unfriendly to FPGAs owing to overly complicated clock networks. Besides accelerating protocol testing, by the time engineers received first silicon they were able to: And perhaps most important was the immeasurable human benefit of getting engineers involved earlier in the project schedule, and having all teams from design to software to validation to applications very familiar with the product six months before silicon even arrived. The impact of this accelerated product expertise is hard to measure on a Gantt chart, but may be the most beneficial. We have since spread this methodology into the Freescale Network and Microcontroller Groups and also use prototypes for new IP validation, driver development, debugger development and customer demos.” Indeed, if we push into the SoC design we will find numerous sub-blocks that follow the same structure, and so on down to the individual gate level. For an individual gate this is trivial, and for small RTL blocks it is still possible. However, as the complexity of a system grows it soon becomes statistically impossible to ensure completeness of the input data and initial conditions, especially when there is software running on more than one processor. At the complete SoC level, we need to use a variety of different verification methods to cover all the likely combinations of inputs and to guard against unlikely combinations. Of course, that may not be a problem and the SoC recovers without any other part of the system, or indeed the user, becoming aware. Verification engineers use powerful methods such as constrained-random stimulus and advanced test harnesses to perform a wide variety of tests during functional simulations of the design, aiming to reach acceptable coverage. However, completeness is still governed by the direction and constraints given by the verification engineers and the time available to run the simulations themselves. As a result, constrained-random verification is never fully exhaustive though it does greatly increase confidence that we have tested all combinations of inputs, both likely and unlikely. A typical use of BPL is to distribute HD video around a home from a receiver to any display via the mains wiring, as shown in Figure 4. These power lines can be very noisy electrical environments, so a crucial part of the development is to verify these algorithms in a wide variety of real-world conditions. It requires very many trials using different channel and noise models, and only FPGA-based prototypes allow us to fully test the algorithms and to run the design’s embedded software on the prototype. In addition, we can take the prototypes out of the lab for extensive field testing. We are able to place multiple prototypes in real home and workplace situations, some of them harsh electrical environments indeed. We cannot consider emulator systems for this purpose because they are simply too expensive and are not portable.” Some of these are best performed using algorithmic or system-level modeling tools, but some extra experiments could also be performed using FPGAs. Is this really FPGA-based prototyping. We are using FPGAs to prototype an idea but it is different than using algorithmic or mathematical tools because we need some RTL, perhaps generated by those high-level tools. Once in FPGA, however, early information can be gathered to help drive the optimization of the algorithm and the eventual SoC architecture.
