Accelerating EDA innovation through SoC design methodology convergence

According to Dr. Walden C. Rhines, chairman and CEO, Mentor Graphics Corp., verification has to improve and change every year just to keep up with the rapidly changing semiconductor technology. Fortunately, the innovations are running ahead of the technology and there are no fundamental reasons why we cannot adequately verify the most complex chips and systems of the future. He was speaking at the recently held DVCON 2014 in Bangalore, India.
A design engineer's project time for doing design has reduced by 15 percent from 2007-2014, while the engineer's time for doing verification had seen 17 percent increase during the same time. At this rate, in about 40 years, all of a designer’s time will be devoted to verification. At the current rate, there is almost no chance of getting a single-gate design correct on first pass!

Looking at a crossover of verification engineers vs. designer engineers, there is a CAGR designers of 4.55 percent, and for CAGR verifiers, it is 12.62 percent.

The on-time completion remains constant, as we look at the non-FPGA project’s schedule completion trends, which are: 67 percent behind schedule for 2007, 66 percent behind schedule for 2010, 67 percent behind schedule for 2012, and 59 percent behind schedule for 2014. There has been an increase in the average number of embedded processors per design size, moving from 1.12 to 4.05.

Macro trends
Looking at the macro trends, there has been standardization of verification languages. SystemVerilog is the only verification language growing. Now, interestingly, India leads the world in SystemVerilog adoption. It is also remarkable that the industry converged on IEEE 1800. SystemVerilog is now mainstream.

There has been standardization in base class libraries as well. There was 56 percent UVM growth between 2012 and 2014, and 13 percent is projected growth in UVM the next year. Again, India leads the world in UVM adoption.

The second macro trend is standardization of the SoC verification flow. It is emerging from ad hoc approaches to systematic processes. The verification paradox is: a good verification process lets you get the most out of best-in-class verification tools.

The goal of unit-level checking is to verify that the functionality is correct for each IP, while achieving high coverage. Use of advanced verification techniques has also increased from 2007 to 2014.

Next, the goal of connectivity checking is to ensure that the IP blocks are connected correctly, a common goal with IP integration and data path checking.

The goal of system-level checking is performance, power analysis and  SoC functionality. Also, there are SoC 'features' that need to be verified.

A third macro trend is the coverage and power across all aspects of verification. The Unified Coverage Interoperability Standard or UCIS standard was announced at DAC 2012 by Accellera. Standards accelerate the EDA innovation!

The fourth trend is active power management. Now, low-power design requires multiple verification approaches. Trends in power management verification include things like Hypervisor/OS control of power management, application-level power management, operation in each system power state, interactions between power domains, hardware power control sequence generation, transitions between system power states, power domain state reset/restoration, and power domain power down/power up.

DVCon India 2014 aims to bring Indian design, verification and ESL community closer!

DVCon India 2014 has come to Bangalore, India, for the first time. It will be held at the Hotel Park Plaza in Bangalore, on Sept. 25-26. Dr. Wally Rhines, CEO, Mentor Graphics will open the proceedings with his keynote. 


Other keynotes will be from Dr. Mahesh Mehendale, MCU chief technologist, TI, Janick Bergeron, verification fellow, Synopsys, and Vishwas Vaidya, assistant GM, Electronics, Tata Motors.

Gaurav Jalan, SmartPlay, chair – promotions committee took time to speak about DVCon 2014 India.

Focus of DVCon 2014 India
First, what's the focus of DVCon 2014 India? According to Jalan, DVCon has been a premiere conference in the US contributing to quality tutorials, papers and an excellent platform for networking. DVCON India focuses on filling the void of a vendor neutral quality conference in the neighbourhood - one that will grow over time.

The idea is to bring together, hitherto dispersed, yet substantial, design, verification and ESL community and give them a voice. Engineers get a chance to learn solutions to the verification problems, share the effectiveness of  the solutions they have experimented, understand off the shelf solutions that are available in market and meet the vendor agnostic user fraternity. Moving forward the expectation is to get the users involved as early adopters of upcoming standards and actively contribute to them.

Trends in design
Next, what are the trends today in design? Jalan said while the designs continue to parade on the lines of Moore’s law there is a lot happening beyond the mere gate count. Defining and developing IPs with a wide configuration options serving a variety of application domains is a challenge.

The SoCs are crossing multi billion gate design (A8 in iPhone6 is 2 billion) with multi-fold increase in complexity due to multiple clock domains, multiple power domains, multiple voltage domains while delivering required performance in different application modes with sleek foot print.

Trends in verification
Now, let's examine the trends today in verification. When design increases linearly, verification jumps exponentially. While UVM has settled dust to some extent on the IP verification level, there is a huge of challenges still awaiting to be addressed. The IP itself is growing in size limiting the simulator and encouraging users to move to emulators. While UVM solved the methodology war the VIPs available are still not simulator agnostic and expecting a emulator agnostic VIP portfolio is still a distant dream.

SoC verification is still a challenge not just due to the sheer size but because porting an env from block to SoC is difficult. The test plan definition and development for SoC level itself is a challenge. Portable stimulus group from Accellera is addressing this. Similarly, coverage collection from different tools is difficult to merge. Unified coverage group at Accellera is addressing this. Low power today is a norm and verifying a power aware design is quite challenging. UPF is an attempt to standardize this.

Porting a SoC to emulator to enable hardware acceleration so as to run usecases is another trend picking up. Teams now are able to boot android on an SoC even before the silicon arrives. With growing analog content on chip the onus is on the verification engineers to ensure the digital and analog sides of the chip work in conjunction as per specs. Formal apps have picked so as to address connectivity tests, register spec testing, low power static checks and many more.

Accelearating EDA innovation
So, how will EDA innovation get accelerated? According to Jalan, the semiconductor industry has always witnessed that startups and smaller companies lead the innovation. Given the plethora of challenges around, there are multiple opportunities to be addressed from both the biggies and the start-ups.

The evolution of standards at Accellera definitely is a great step so as to bring the focus on real innovation in the tools while providing a platform for the user community to come forward sharing the challenges and proposing alternates. With a standard baseline that is defined with collaboration from all partners of the ecosystem, the EDA companies can focus on competing on performance, user interface, increased tool capacity and enabling faster time to market.

Forums like DVCON India help in growing awareness on standard promoted by Accellera while encouraging participants from different organizations and geographies join to contribute. Apart from tools areas where EDA innovation would pick up include new IT technologies and platforms – Cloud, Mobile devices.

Next level of verification productivity
Where is the next level of verification productivity likely to come from? To this, Jalan replied that productivity in the verification improves from different aspects. While faster tools with increased capacity comes from innovation at EDA end, standard have played an excellent role in addressing it. UVM has helped in displacing vendor specific technologies to improve inter-operability, quick ramp up for engineers and reusability. Similarly on power format, UPF has played an important role in bridging the gaps.

Unified coverage is another aspect where it will help in closing early with coverage driven verification. IPXACT and SystemRDL standards help further in packaging IPs and easier hand off to enable reuse. Similarly other standards on ESL, AMS etc help in closing the loop holes that prevent productivity.

New, portable stimulus specification now being developed under Accellera that will help in easing out test development at different levels from IP to sub system to SoC. For faster simulations, the increase in adoption of hardware acceleration platforms is helping verification engineers to improve regression turn around time.

Formal technologies play an important role in providing a mathematical proofs to common verification challenges at an accelerated pace in comparison to simulation. Finally events like DVCON enables users to share their experiences and knowledge encouraging others to try out solutions instead of struggling with the process of discovering or inventing one.

More Indian start-ups
Finally, do the organizers expect to see more Indian start-ups post this event? Yes, says Jalan. "We even have a special incubation booth that is encouraging young startups to come forth and exhibit at a reduced cost (only $300). We are creating a platform and soon we will see new players in all areas of Semiconductor.

"Also, the Indian government's push in the semiconductor space will give new startups further incentive to mushroom. These conferences help entrepreneurs to talk to everyone in the community about problems, vet potential solutions and seek blessings from gurus."

Apple continues to 'wow' all over again!

Apple has done it again! Trust the Cupertino-based company to come up with great products -- time after time, after time!

Today, the iPhone 6 and iPhone 6 Plus have been announced! These were followed quickly by announcements regarding the Apple Watch and Apple Pay.

The phones have 4.7-inch and 5.5-inch Retina HD displays, and packed with innovative technologies in an all-new dramatically thin and seamless design. Also, they are engineered to be the thinnest ever. Both models run on the all-new A8 chip and include iOS 8, the very latest version!

The Apple Pay now allows a very easy way to securely pay for physical goods and services in stores or apps with the touch of a finger. You can pay securely and conveniently in stores by holding the phone near the contactless reader and keeping a finger on Touch ID. There is absolutely no need to unlock your iPhone or launch an app!

The Apple Watch introduces a specially designed and engineered Digital Crown that provides an innovative way to scroll, zoom and navigate. It is Apple’s most revolutionary navigation tool since the iPod Click Wheel and iPhone Multi-Touch.

Analysys Mason believes that smartwatches will become the dominant wearable smart device by sales in early 2017, and that, Apple will drive this market. Analysys Mason also feels that Apple has an advantage in the race for mobile commerce and payments dominance.

IHS reports that Apple rarely invents new markets, despite its reputation. But when Apple launches a new product category, it attempts to redefine the market. Apple Pay may also get introduced internationally as soon as possible.

All of my blogs are now up for sale! ;)

My dear friends, as most of you are probably aware, Webstatsdomain.org has estimated Pradeep's Point! at a whopping $19.1 billion in July 2014. As I write this post, the number has slightly reduced to $16.6 billion. Pradeep's Point! is my flagship blog! ;) 

Friends, I am now in the process of selling off Pradeep's Point! as well as all of my other blogs! I hope that they will all remain, as will the content, but the owner (or owners) will be different! Perhaps, the blogs could have a different name!

Maybe, the new owners will try and keep me on board, too! ;) (I hope, they do).

It's been a long time! I started Pradeep's Point! back in 2007, having just returned after my second stint in Hong Kong and China. Actually, it was initially under Blogspot as Pradeep Chakraborty's Blog - when it won the first international award - Pradeep Chakraborty's Blog was selected as the best in the world in the Electronic Hardware category for 2008-10, by Electronics Weekly, UK. I remember and would again like to thank all of those folks who voted for me to the first ever international title! :)

Next, Pradeep Chakraborty's Blog received an Honorable Mention @ Blognet Awards 2009! That's also the time when someone succeeded in adding malware to that blog, and there was absolutely no fault of mine, and it was later removed by Google! I recall spending an entire night migrating the content to Wordpress, where I had a secondary blog - Pradeep's Point!

I moved on to Wordpress, migrated all of the posts, and Pradeep's Point! was reborn, or rather, born!

Thereafter, it has been hugely satisfying journey for me! I managed to pick up at least one international award / international recognition for all of my blogs, every year, till this year! ;) These are:

PC’s Semicon Blog awarded the Top Digital Media Blog by Online IT Degree (in November 2010).

* Green Gadget of Texas, USA, awarded Pradeep's Point! as the “Featured Tech Site” for 2011!

* In August 2014, PC's Electronic Components Blog was ranked 11th in the "Top 101 Best Resources for Electrical Engineers.”

Now, this year, the huge estimation of Pradeep's Point! by Webstatsdomain.org!

As I write, two folks - from Bangalore -- are trying to gather funds to buy Pradeep's Point! Although, my personal preference is for a very good friend! :)

The other five blogs up for sale are:
* PC's Semiconductors Blog. (Won an award)
* PC's Solar Photovoltaics Blog.
* PC's Electronics Blog.
* PC's Electronic Components Blog. (Won two awards)
* PC's Telecom Blog. (Won an award)

I already have feelers, again from Bangalore, for buying out PC's Semiconductors Blog and PC's Electronic Components Blog. Again, I would prefer, if a friend, hopefully, tried to buy all of them, together! One blog definitely can't do without the other - that's my estimation! ;) Well, let's see what happens!

So, my dear friends, once again, it has been a pleasure serving you all via my blogs! Now, they are in the process of being sold off. Whoever buys those, will definitely have a great future! :) (In case, I change my mind, the blogs will remain as they are! ;) )

Cadence now realizing EDA 360 vision: Nimish Modi

The EDA 360 was an industry vision. It reflected a change in market requirements. It was application driven system design. From a Cadence perspective, the company has done system design enablement, according to Nimish Modi, senior VP, marketing and business development, Cadence Design Systems Inc.

In Apple's case, the iOS is unique. Cadence feels that the heart of the design is the SoC. The electrical analysis is becoming very important. For instance, how do you optimize before tape-out? Hardware and software conversion presents a huge problem as well. The IP plays an important part. Cadence did IP-as-a-service. It now has an IP strategy.

Today, EDA is about possibility, not productivity. Cadence provides tools and content for semiconductor and systems companies. It is now realizing the EDA 360 vision.

On IP
According to Modi, each IP is immensely complex. Standards based or interface IP is not enough! Silicon-proven design is the need of the hour. Now, more and more IP blocks are said to be coming together.

FPGA-based prototyping
Cadence is offering the Palladium XP, and its primary use is for system verification. Software development is becoming a little bit difficult. People are providing software prototypes. The Palladium compile, turnaround and debug are very fast, best-in-class. All memory, clocking, partitioning, etc., is now automated.

The capacity of the Protium platform is 100 million gates. It will enable hardware and software developers. The use model for Protium is:
* Hardware folks use it for hardware regression.
* Software folks use it for early software development.

The main value proposition is the faster bring-up time. Also, the Palladium hybrid model helps customers overcome the boot problem. It is a hybrid of emulation and virtual prototyping. The dynamic power analysis is another issue. The Palladium hybrid model helps to do the testing.

Collaboration with ARMARM provides processor IPs. Cadence works closely with ARM. Cadence is also co-optimizing its tools to provide the best PPA. Physical libraries and tools get optimized. Cadence's tools are optimized for ARM architecture. Cadence is also the first ones on the access to the V8 ARM models.

Need for efficient product development ecosystem: CDNLive 2014

According to Vasudevan Aghoramoorthy, VP at Wipro Technologies, a product-centric approach targets multiple customers as well as diverse needs.An example is the desktop server. He was delivering the guest keynote on day two at the CDNLive 2014 in Bangalore, India.

For an app-centric approach, it addresses one specific market and has multiple end customers.Examples are set-top boxes and mobile phones. A services-centric approach addresses the service providers' needs. Examples would be PoS machines, base stations, ATMs, patient monitors, etc.

A customer-centric approach has diverse needs. These are faster time-to-market, diversification into complementary markets, reduction in product costs, completion of product portfolio, market development, expansion and customization, as well as leveraging analytics.

As a case study, he referred to Wipro engineering a low-cost, low-power ATM with battery back-up. It has been implemented with multi-language display and voice instruction, with spoil-proof keyboard. It also has a fingerprint biometric reader, and serves as a tamper-proof machine for secured transactions.

What did the product development process achieve? Product cost was reduced by 60 percent, and power consumption was reduced by 50 percent. The concept to deployment time was 10 months. An innovative design was used to address the strict power requirements. Wipro used an agile approach to develop the product.

Another case was of a patient-monitoring machine at a fraction of the cost. There was cost reduction by 5X at the physician's end and 50 percent at the patient's end. There was ease of use for physicians as connectivity options were enabled for smartphones and tablets.

All of these cases tell us that the product development ecosystem must be efficient. Product management and understanding use cases are key. In Wipro's  case, the development methodology was adapted to market needs. Product differentiation can be done by software. There is a need for cross-disciplinary engineering skills. It will lead to newer methodologies, enabling joint reviews in collaboration for cross-disciplinary projects.

Market opportunities are available for product development and retaining value. Market-driven needs drive innovation, and possibly, lead to the growth of the ESDM sector in India.
