Design verification trends and role of emulation

Posted on Updated on

Sanjay Gupta, senior director of R&D, Mentor Emulation Division, Mentor, presented on the design verification trends and role of emulation.

Mentor2Verification needs are expanding beyond traditional functional verification. SoC power analysis, coverage closure and DFT validations are critical. Vertical market segment focus is crucial as verification needs are different for different verticals. Verification teams are global teams. Veloce platform addresses the modern verification challenges.

Talking about the design trends, ~31 percent of designs use over 800 million gates and ~20 percent use over 500 million gates.Next, 72 percent of designs contain embedded processors, and 49 percent designs contain two or more processers, while 16 percent designs have eight or more processors.

As for ASIC/IC completion to the original schedule, 61 percent designs were behind schedule in 2014, which increased to 69 percent during 2016. The number of required ASIC/IC spins before production had become seven spins or more in 2016.

Regarding verification trends, as for more design engineers vs. verification engineers, design engineers were growing at CAGR 3.6 percent, while verification engineers were growing at CAGR 10.4 percent, from 2007-2016. The ASIC/IC verification engineers were spending 39 percent of their time at debugging, 22 percent each at creating test and running simulation, and testbench development, and 14 percent time in test planning.

SystemVerilog was a clear leader at the ASIC/IC verification language adoption, while Accelera UVM was a clear leader at the ASIC/IC testbench methodology adoption trends.

In power and coverage, 72 percent more designs wre actively managing power in 2016 as against 59 percent in 2007. Among the power intent trends, the UPF 2x was a clear leader among notations used to describe power intent. Functional coverage is just nearly on par with code coverage, followed by assertions and constrained-random simulation, as far as the ASIC/IC dynamic verification trends are concerned.

Challenges for verification include larger, more complex chips, as well as the increasing software content. Transistor count for select ICs will likely reach 15 billion gates by 2022.

Vertical segments are facing constant innovation. In networking, SDN emergence is driving complexity, size, and port count. There is an increased importance of software. Networking is driven by Big Data, cloud and mobility.

Safety is critical verification for automotive design. Veloce delivers the functional safety verification. Emulation has moved to virtualization with Veloce2. Data-center friendliness and enterprise-level usage are prime. Veloce Strato has accelerated and moved on to the application age, and has a vertical market focus.

Crystal chip is the brain of the Veloce emulation platform. A chip is designed exclusively for emulation: fast compile and efficient, full visibility. The chip, system and software are architected together to optimize the emulation capabilities and productivity. The Veloce Strato offers the lowest cost of ownership.

Veloce power app offers low-power verification at SoC level where power controls come from the application software, handles large SoC (RTL/Gate) with full visibility, performs complete verification (e.g. OS boot) and shows accurate power numbers based on real switching activity.

You can also do low power verification with Veloce. There is broad UPF 2.x support and UPF 3.0 support is planned by the end of 2017. Veloce coverage app has comprehensive SVA assertion support, SV functional coverage, code coverage, standard UCDB support and merged with simulation UCDB, and flow to enable XML merge with other platforms.

Veloce structured around verticals

Posted on

Anoop Saha, Mentor, did a presentation on Veloce vertical solutions at the Emulation Conference in Bangalore.

MentorVeloce solutions are used across networking, storage, multimedia, mobile, CPU, automotive and military aeronautics. Veloce is structured around verticals to be segment focused, identify and address segment specific challenges, and identify gaps early on.

Veloce solutions are connecting the DUT to the external stimulus. iSolve speed adaptors connect real-life systems with the emulator. The Virtualab peripherals — VirtuaLab is the software representation of a speed adaptor. The Veloce transactor library – Veloce compatible verification IP. Transactors (VTL) to integrate with users UVM testbench and lower the abstraction layer.

In networking, for instance, the network switch is driving complexity. There is shift to SDN driving chip size and high port counts. Next, 5G is also driving new technology
and standards. Veloce for networking is offering solutions on top of core emulation platform. The verification flow is expanding to include Lab system validation. As of now, SDN is said to be creating a methodology shift. Mentor is said to be the only vendor with a complete offering.

Verification can no longer ignore firmware. Emulation enables earlier firmware development. Software debug is done with Codelink. The Veloce power app is used for broad base analysis. Veloce also offers complete solution for multimedia.

There has also been an industry shift from spec to benchmark. Many new apps target benchmarks for mobile devices. Examples are the AnTuTu benchmark, Geekbench for CPU and GPU benchmark, GFXBench, a GPU graphics centric benchmark, Android smartphone and tablet benchmark, etc.

Emulation challenges 5G and beyond

Posted on Updated on

Mentor, A Siemens Business, held a one-day conference on emulation in Bangalore and Hyderabad. I am thankful to my friends, Veeresh Shetty and Montu Makadia, for helping me attend this conference.

Shankar Bhat, Director, Engineering, Qualcomm India Pvt Ltd, in his keynote, titled 5G and Beyond – Emulation Challenges, said that a shrinking time to market, and stringent DPPM requirements drive the future of verification. Verification scope will extend from just hardware verification to software enablement. The emulation footprint in verification will significantly improve.
Mentor1
He added that mobile has been making a leap every 10 years. Today, it is redefining everything by creating the connectivity fabric for everything and bringing new levels of on-device intelligence. The long-term vision is to transform everything through intelligent connected platforms.

There is likely to be $12 trillion worth of 5G-related goods and services in 2035. Mobile is driving technology nodes and innovation. Verification focus has expanded from functionality to coverage to performance, on to power to yield and DPPM (defective parts per million). There is an over 30 percent NRE (non-recurring engineering) cost on design verification and emulation.

Post silicon validation and software testing time has been shirking. The post silicon test content, and software need to be fully validated before silicon arrival. Here, emulation plays a significant role in software readiness.

Regarding the key verification challenges, these are:
* Increased complexity: Test counts have increased, and there are much complex power structure and power domains. Also, there are challenging performance scenarios.

* Long simulation time: Simulator efficiency is not scaled. It is not able to complete all verification before tape out.

* Software enablement: Software expects fully verified design and settings.

* Customer enablement and DPPM reduction.

Emulation advantages
Emulation has several advantages. It has significantly faster run time, 1000X+ compared to simulation. It mimics hardware and closure to silicon. There is quick test portability between platforms.

Emulation will play significant role in design qualification, in both pre- and post-silicon phases. Software enablement will help achieve faster time-to-market. The challenges faced by emulation are a high NRE cost, limited debug capability, compilation time is still high, there are limited power verification capabilities. There are higher hardware costs as well in gate level verification, as it is difficult to fit the full SoC into the FPGA.

Emulation will play a significant role in hardware and software co-simulation. Tool portability is key. Verification will use multiple tools and flow. There will be the interpretability of tests, and data will be critical. EDA companies need to develop cost-effective emulation platforms.

Earlier, welcoming the audience, Ruchir Dixit, Technical Director-India, Mentor, said that the status quo is uncomfortable. He compared the cost of laying a metro network in Bangalore, which can cost between Rs. 8,000-14,000 crores. For emulation, while, it was expensive, it was about time that developers got used to it.

StanChart redefining banking with connected thinking

Posted on Updated on

Standard Chartered Bank is developing the power of the interconnected strategy. StanChart is also redefining banking with connected thinking. Digital is combining with technology to trigger different touch points. Standard Chartered Bank also opened its new Global Business Services (GBC) center in Bangalore, early this month.

Kwan Chee Sun, Head, Standard Chartered Global Services, India, said that the fourth industrial revolution — the digital age — blurs the lines between digital, biological, etc. The bulk of the increase will happen in the technology space. He referred to Smile To Pay, a service offered by KFC and AliPay started in China.

Gorriz
Dr. Michael Gorriz, Group CIO, said that Standard Chartered had been discussing the future of banking for ages. How will StanChart look like 10 years down the road?

He said: “Five years ago, smartphones became pervasive and changed the face of banking. Banking is about basic services — store, lend and borrow money. We are now experiencing a world of digitised money. Technology has broken down the barriers. In future, digital will be dominant in bank-customer relations. Data and analytics will help banks to serve customers better in the future. We are now investing US$ 3 billion in improving our global footprint.

“We partner with fintech companies and incorporate them into our atmosphere. We have also built up an accelerator lab. Currently, we have a challenge with legacy systems. In the future, we would like an adaptive landscape. Investment in APIs is critical.”

Trends in banking
Designed for SMEs, Standard Chartered’s Straight2Bank (S2B) is a fully-integrated Internet banking platform that allows you to perform all your transaction and information.

Talking about technology trends in banking, he said: “The Straight2Bank app has an interface for commercial and corporate customers. Digital payments are engrained into the interface. There will be data-driven business models. Big Data can help us gaining insights into the real needs of customers. Next, fraud detection is important for us. Also, blockchain is helpful in bringing transparency into banking.”

Gorriz noted that StanChart currently operates in 68 countries. The learnings among the different markets are exchanged quickly. StanChart supports over 9 million customers today in retail banking.

James Dolphin, CIO, Retail, Private Banking and Wealth Management, said that banks create and convey trust, adding: “Cavalier people generally write the best software. We are now competing for software engineering talent.” He added that banks had been mistrustful to open source for a very long time. That scenario was changing.

Dolphin noted that the current scenario of software development resembled the waterfall vs. agile development of software. Digital product owners tell the team what needs to be done. The team of engineers have two weeks to change their minds, if needed. “We are now looking at areas where the engineers and software developers can run speed, or, be on a run-on condition. Our engineers should have the ability to create something very quickly.”

In a presentation made via video, Tom Siebel, CEO, C3 IoT, said that IoT is about the sensoring of value chains. Smart, connected products are today transforming companies. The C3 IoT platform allows the company to collect and analyze data.

Focus on data
Shameek Kundu, chief data officer, Standard Chartered Bank, during a chat, said: “Data will be very important. We are working on expanding the credit transaction data. We are also working toward building a safer infrastructure for the bank. In Singapore, we have combined geospatial infrastructure with real-time offers. This exercise is building on the data asset.”

Regarding the smaller traders, he said: “We can bring small manufacturers into our stream. Having access to good data will help us in expanding credit. Technology can play a big role in all of this. Our strengths are the advantage of investing in technology and improving on our footprint.”

As for blockchain, he noted: “Blockchain is a way to build trust. We have invested in Ripple, and worked with AIG. Our priority remains to upgrading on services and technology to serve customers.” Standard Chartered Bank made a strategic investment in Ripple, a leading distributed ledger company, last September. The investment will accelerate the Bank’s digitisation agenda in distributed ledger technology as it explores new ways of adding value to its clients and the industry.

He continued: “We actually went open source in banking. As the customers’ needs evolve, there will be a need to invest in technology. We recognize that we have to work at the customers’ requirements and then, meeting them. Technology companies are also building specific solutions to support for our services.”

Engineering analytics gaining momentum in India: MathWorks

Posted on Updated on

MathWorks, founded 1984, is a global software company with headquarters in Natick, Massachusetts, USA. Engineers and scientists worldwide rely on products – MATLAB, the language of technical computing, is a programming environment for algorithm development, data analysis, visualization, and numeric computation.
Simulink is a graphical environment for simulation and Model-Based Design of multidomain dynamic and embedded systems.

MathWorks produces nearly 100 additional products for specialized tasks such as data analysis, image processing, control design, wireless and radar.

K RaoKishore Rao, MD of MathWorks India, said that engineering analytics is gaining momentum in India. The data analytics space is actually very strong. There is an increased use of embedded analytics. Customers want to have analytics happening on the cloud as well as on the device.

“A recent trend is to have data analytics integrated with simulation; to take the insight from data and build better and smarter products using simulation. MathWorks is uniquely positioned as we have an integrated solution with data analytics and model-based design. With this you are really driving more efficiency into your products and business. This is happening across the industry, eg, automotive, industrial automation. Some companies are also talking of having a digital twin.

“Today, engineers are creating smarter and more efficient products. Also, they are focusing on predictive maintenance to improve the reliability of the products. Therefore, you are able to drive the maintenance cycles well in advance. With the growing number of sensors on products, predictive maintenance is a key focus for companies to leverage the data from the sensors. Some also call this sensor analytics.

MathWorks has a strong focus towards academia, and works with engineering institutes across India. Rao added: “Today, over 1,200+ engineering colleges in India use our products. These include IITs, NIITs, and several state engineering colleges.”

MathWorks offers a ‘Campus Wide license’ to institutes which opens up access to the tools to all faculty and students in classrooms, labs, across engineering, science, business, and other disciplines to use MATLAB and Simulink for data analytics, model-based design of embedded and cyber-physical systems, and many other technology areas. This will enable improved analysis and problem-solving skills through hands-on, project-based learning; improved understanding of underlying concepts and theory; and leading-edge academic research using the same tools widely used in industry.

“We have an integrated approach to academia. One aspect is providing access to tools. This is significantly enhanced through the campus wide license. The other important aspect is to help in the usage of tools by professors and students. A team of technical evangelists works with professors to help them incorporate tools into the courses, and also drives student interest through project work and student competitions.

“One challenge we hear is that software tools that are bought by colleges do not get used sometimes. As the ‘campus wide license’ is an annual term license, it keeps people honest on both sides (institute and software supplier) as the license needs to be renewed annually and will not be renewed if the usage is not good.

“We have been promoting the campus wide license for the last three years, and it has really picked up over the last 12 months. Today we have over 50 institutes with the campus wide license and this would grow to 90 by the end of 2017. We have a Big Hairy Audacious Goal (BHAG) of having 500+ institutes on campus license model by 2020.

Tools for embedded vision
MathWorks also provides software tools for embedded vision. Rao said: “Vision is a huge area of interest. We are providing tools such as Computer Vision, which use deep learning techniques to gather insight from image and video data.

“Image and video applications are being leveraged by all industries today – automotive, aerospace, medical, consumer electronics, industrial equipment verticals. This is critical in safety critical applications such as ADAS or automated driving. We can share an example from Scania where they used MathWorks tools for a safety critical application such as Advanced Emergency Braking System which involved sensor fusion of both radar and camera sensor data.”

How can machine builders prepare for IIoT? Rao said: “We are doing things in Industry 4.0! Data analytics and sensor analytics are focus areas for us. We are working with several industrial equipment customers on predictive maintenance.

“We also work with start-ups, and are seeing a huge interest. We have a start-up program, where our products are offered at a big discount. A lot of the start-ups that we are working with are in medical devices, aerospace and automotive “We provide a combination of our products and services for the start-ups. The value from MATLAB and Simulink is immense.

The go-to-market strategy is three-pronged:
* Commercial customers – we work with the commercial customers in areas of sensor analytics and Model based design to help them develop better products

* Academic Institutions – working with engineers. Making sure they are trained on industry standard tools like MATLAB

* Start-up-ups – where we offer them special price, services and mentorship.

This March, MathWorks announced the release 2017a of the MATLAB and Simulink Product Families. Rao said: “We have a new release 2017b, that will be out in October. The release adds new important deep learning capabilities that simplify how engineers, researchers, and other domain experts design, train, and deploy models.”

ROHM intros Trench SiC MosFET to make renewable energy affordable

Posted on Updated on

ROHM India has introduced the Trench SiC MosFET technology to make renewable energy affordable. The next step will be innovations for the local automotive industry.

Power electronics is now enabling renewable energy harvesting. Increasing rural-electrification, adoption of home appliances, industrialization and population is bringing more pressure on the grid, and the power generation capacity.

image025India will be the largest importer of coal, natural gas and oil by 2040. The focus on renewable energy has gone up, leading to increased generation and decreased losses. Smart grid will enhance the efficient distribution of power.

Simlife Electric Pvt Ltd introduced the GAN2000, India’s first hybrid battery backed grid-tie solar power generation system, a combination of grid-tie and off-grid. It is designed, developed and manufactured in India. Power electronics reduces the cost/kW, and enables higher switching frequencies, magnetics and SiC.

Making energy affordable
Energy can be made affordable and achieved by extraction of power from multiple sources that are efficient and cost effective. The power conversion is made more efficient and is always available. It is also less resource intense. ROHM recommends SiC Trench MosFETs for high-power applications.

Rohm’s 3G SiC Trench MOS improves performance. The SiC MosFET is a near ideal switch resulting in low overall losses. Using the SiC reduces the overall system cost. High reliability of SiC improves system reliability.Rohm1

As for the future trends for wide-band gap (WBG) semiconductors, 10X growth is expected for WBG products by 2023! Dominant space:s are the SiC = 600V and GaN = 600V. Major growth areas are EV/HEV, chargers, solar, industrial drives.

Applications such as solar/wind power, industrial equipment, EV/HEV, large-scale data center servers, and home electronics/AC benefit from the use of SiC.

ROHM Semiconductor India Pvt Ltd (RSI) a subsidiary of ROHM Co. Ltd, Kyoto, Japan, announced an array of power solutions like SiC, IGBT, and gate drivers, for improving the power conversion efficiency. These products are intended to meet the harsh condition of India’s rapidly growing power infrastructure.

The improvement in size and efficiency owing to the adoption of the power solutions from RSI, like gate drivers, trench SiC MOSFETs, and IGBTs, play a vital role in enabling small scale and distributed power plants for tapping solar and wind energy. A ~2 percent increase in efficiency along with the reduced cooling requirements can bring in a considerable cost saving for the end customers, besides improving the reliability of the power converters.

This will help bridge the demand supply gap, which is “more from less, for more”, thus reaching more people. The distributed power generation, besides reducing a huge burden on our grid, reduces the transmission and distribution losses.

ROHM’s power solutions include a broad range of power devices, IGBT, SiC, besides Silicon MOSFET and gate drivers designed to achieve improved efficiency in high power applications.

Britto Edward Victor, Design Centre-head, ROHM Semiconductor India, said: “Our focus is on home appliances, industrial power and automotive. We now work on power conditioners. We released the silicon carbide (SiC) MOSFET. It is also used in rural electrification. Rohm Semiconductor India has a design center in Bangalore. The design center has an Application Engineering group to provide technical support to India customers.”
