Agnisys Inc. was established in 2007 in Massachusetts, USA, with a mission to deliver innovative automation to the semiconductor industry. The company offers affordable VLSI design and verification tools for SoCs, FPGAs and IPs that makes the design verification process extremely efficient.
Agnisys’ IDesignSpec is an award winning engineering tool that allows an IP, chip or system designer to create the register map specification once and automatically generate all possible views from it. Various outputs are possible, such as UVM, OVM, RALF, SystemRDL, IP-XACT etc. User defined outputs can be created using Tcl or XSLT scripts. IDesignSpec’s patented technology improves engineer’s productivity and design quality.
The IDesignSpec automates the creation of registers and sequences guaranteeing higher quality and consistent results across hardware and software teams. As your ASIC or FPGA design specification changes, IDesignSpec automatically adjusts your design and verification code, keeping the critical integration milestones of your design engineering projects synchronized.
Register verification and sequences consume up to 40 percent of project time or more when errors are the source of re-spins of SoC silicon or an increase in the number of FPGA builds. IDesignSpec family of products is available in various flavors such as IDSWord, IDSExcel, IDSOO and IDSBatch.
IDesignSpec more than a tool for creating register models!
Anupam Bakshi, founder, CEO and chairman, Agnisys, said: “IDesignSpec is more than a tool for creating register models. It is now a complete Executable Design Specification tool. The underlying theme is always to capture the specification in an executable form and generate as much code in the output as possible.”
The latest additions in the IDesignSpec are Constraints, Coverage, Interrupts, Sequences, Assertions, Multiple Bus Domains, Special Registers and Parameterization of outputs.
“IDesignSpec offers a simple and intuitive way to specify constraints. These constraints, specified by the user, are used to capture the design intent. This design intent is transformed into code for design, verification and software. Functional Coverage models can be automatically generated from the spec so that once again the intent is captured and converted into appropriate coverage models,” added Bakshi.
Using an add-on function of capturing Sequences, the user is now able to capture various programming sequences in the spec, which are translated into C++ and UVM sequences, respectively. Further, the interrupt registers can now be identified by the user and appropriate RTL can be generated from the spec. Both edge sensitive and level interrupts can be handled and interrupts from various blocks can be stacked.
Assertions can be automatically generated from the high level constraint specification. These assertions can be created with the RTL or in the external files such that they can be optionally bound to the RTL. Unit level assertions are good for SoC level verification and debug, and help the user in identifying issues deep down in the simulation hierarchy.
The user can now identify one or more bus domains associated with Registers and Blocks, and generate appropriate code from it. Special Registers such as shadow registers and register aliasing is also automatically generated.
Finally all of the outputs such as RTL, UVM, etc., can be parameterized now, so that a single master specification can be used to create outputs that can be parameterized at the elaboration time.
How is IDesignSpec working as chip-level assertion-based verification?
Bakshi said: “It really isn’t an assertion tool! The only assertion that we automatically generate is from the constraints that the user specifies. The user does not need to specify the assertions. We transform the constraints into assertions.”
Tensilica DPU solutions are meant for broad applications. It is focusing on three key verticals — Hi-Fi audio voice, IVP imaging and Diamond controllers, as well as the Xtensa. Tensilica will expand the Cadence IP footprint in SoCs. This compliments Cadence and Cosmic Circuits interface and analog IPs.
How does all of this fit into Cadence’s vision of an IP factory? According to Chris Rowan, founder and CTO, Tensilica, there will likely be an IP bazaar, architected for efficiency, quality and strong focus on integration. He was speaking on the concluding day of the 13th Global Electronics Summit at Santa Cruz, USA.
Complex imaging functions are now everywhere. There are some challenges here such as computational demands. The off-load opportunity means more operations, and lower power per operation.
The Tensilica IVP – image/video processing family consists of the IVP, a high-performance DSP subsystem. It is built for low energy handheld devices. It also has licensable, synthesizable core with rich software tools and libraries. The IVP core has 32 element engines. The IVP has many parallel ‘element engines’ + Xtensa control programmed as SMID uniprocessor. Application examples include feature detection, 3D noise reduction filter, and video stabiilizer.
IVP is meeting tomorrow’s imaging requirements. It is built for very high imaging efficiency. It is easy to program and is scalable — and can use multiple cores.There is a huge market in many applications. An example of how Tensilica will fit into Cadence’s IP factory is the DTV application.
Together, Cadence and Tensilica will increase customer value. They will accelerate the time-to-market with solution proven customizable design IP. There will be fully integrated data plane solutions for optimized solutions, power and area for various applications. High quality IP subsystems are tested to work optimally together. It is highly complementary to partner CPUs. It is also highly complementary to Cadence’s broad connectivity/AMS design IP, verification IP offerings, and foundry-qualified SoC design tools.
The partnership will also bolster Cadence as a next-generation IP provider. There will be an enhanced portfolio of advanced IP in advanced nodes spanning a wide range of applications. It will address seamless designs from architecture definition to silicon
tape-out. It will also strengthen solutions to address key market segments.
Last week (March 11, 2013), Cadence Design Systems Inc. entered into a definitive agreement to acquire Tensilica Inc., a leader in dataplane processing IP, for approximately $380 million in cash.
With this acquisition, Tensilica dataplane processing units (DPUs) combined with Cadence design IP will deliver more optimized IP solutions for mobile wireless, network infrastructure, auto infotainment and home applications.
The Tensilica IP also complements industry-standard processor architectures, providing application-optimized subsystems to increase differentiation and get to market faster. Finally, over 200 licensees, including system OEMs and seven of the top 10 semiconductor companies, have shipped over 2 billion Tensilica IP cores.
Talking about the rationale behind Cadence acquiring Tensilica, Pankaj Mayor, VP and head of Marketing, Cadence, said: “Tensilica fits and furthers our IP strategy – the combination of Tensilica’s DPU and Cadence IP portfolio will broaden our IP portfolio. Tensilica also brings significant engineering and management talent. The combination will allow us to deliver to our customers configurable, differentiated, and application-optimized subsystems that improve time to market.”
It is expected that the Cadence acquisition will also see the Tensilica dataplane IP to complement Cadence and Cosmic Circuits’ IP. Cadence had acquired Cosmic Circuits in February 2013.
What are the possible advantages of DPUs over DSPs? Does it mean a possible end of the road for DSPs?
As per Mayor, DSPs are special purpose processors targeted to address digital signaling. Tensilica’s DPUs are programmable and customizable for a specific function, providing optimal data throughput and processing speed; in other words, the DPUs from Tensilica provide a unique combination of customized processing, plus DSP. Tensilica’s DPUs can outperform traditional DSPs in power and performance.
So, what will happens to the MegaChips design center agreement with Tensilica? Does it still carry on? According to Mayor, right now, Cadence and Tensilica are operating as two independent companies and therefire, Cadence cannot comment until the closing of the acquisition, which is in 30-60 days.
Happy new year to everyone! Here is an outlook for the electronics and semiconductors sectors in 2013, provided by Jaswinder Ahuja, corporate VP and MD, Cadence Design Systems (India) Pvt Ltd. (Thanks a lot, Pallavi).
First, the past year, 2012, in review.
Globally, 2012 has been a challenging year for the semiconductor industry with the economic slump in Europe and the US. However, the long term outlook remains positive, with Gartner reporting that the growth in the electronics and semiconductor industries will outpace world GDP growth till 2016.
In India, the ambiguity around the telecom market, traditionally the biggest consumer of semiconductor equipment, was the main handicap to growth. On the positive side, the passing of the National Policy on Electronics (NPE) in 2012 promises a much-needed fillip to the electronics ecosystem. In 2013 we expect to see a positive impact in terms of home-grown electronics thanks to the provisions of the Policy.
Worldwide technology trends in 2013
User experience is the driving force behind many of the semiconductor design trends that we will see in 2013 and beyond. Consumers are demanding devices on which games, music, cameras, internet, and other apps all run simultaneously and seamlessly. As a result, mobility, application-driven design, video, cloud and security, all of which enable an enhanced user experience, are the drivers of the electronics and semiconductor world today.
Mobility is the single biggest driver for the semiconductor industry. The pervasiveness of mobility does not only affect the telecommunications industry, but also entertainment, home electronics, automotive and medical electronics.
For example, cutting edge mobile solutions in the healthcare field include devices that can monitor blood pressure and blood sugar levels remotely, and then transmit the readings to the physician for diagnosis and treatment; in the automotive sector, in-vehicle infotainment is expected to be the next big thing and end-consumers can look forward to real-time traffic reports, weather information, and entertainment options from next-generation cars.
Mobility has fundamentally altered how we produce and consume information. In the future, we can expect that devices will go one step further and actually interact intelligently with the user – we see the first steps of that with Apple’s Siri software.
Mobility has also created a completely new market for applications that enable a more interactive and satisfying user experience. It is via applications that system companies differentiate themselves and stand apart from the competition. The need to have applications on all kinds of devices is posing unique challenges to the semiconductor and EDA companies.
Whereas traditionally the hardware (silicon) was built first and then the software was added later, now developing the software and designing the hardware are becoming a parallel process. This gives rise to new EDA technologies that enable early software development using software models of system hardware long before silicon is ready. We will see this new way of designing continue to be a challenge going into 2013.
Per reports from Cisco, video will soon drive more than 90 percent of all global traffic on the Internet. As more and more entertainment and collaboration tools are launched, bandwidth-hungry video traffic will drive growth both in the end consumer market (mobile platforms) and the enterprise space (networking industry).
The cloud is closely intertwined with the growth in mobility – it is the cloud of network servers and backbone equipment that deliver the content and value to all mobile devices. For every 600 smart phones and every 120 tablets, one dedicated server is needed. With the demand for mobiles showing accelerated growth, the need for cloud computing technologies will be another key driver for the semiconductor industry.
Security underpins our information age. The vast amount of data residing in mobile platforms and cloud architectures is extremely vulnerable. As we move into 2013, we foresee a sharper focus on securing data and critical infrastructure from theft and hacker attacks.
How will 2013 turn out to be for the global semiconductor industry? Will there be growth for the global EDA industry? Importantly, how will the Indian semiconductor industry perform in 2013? I asked Jaswinder Ahuja, corporate VP and MD, Cadence Design Systems India these questions.
Outlook for global semicon industry in 2013
First, how is the outlook for global semiconductor industry in 2013 going to be? Ahuja said: “The long term outlook for the semiconductor industry remains positive, with mobility and cloud computing being the key drivers. The global economy is forecast to grow around 4 percent annually through 2016, according to an April 2012 report from the International Monetary Fund (IMF).
“In its June 2012 report, Gartner predicted growth in electronics and semiconductor industries to outpace that of the world GDP growth, at 5½ percent annually to approach $2 trillion for electronics and 6 percent annually for semiconductors through 2016. So, the semiconductor industry outlook remains very positive overall.
“In the near term, multiple challenges will need to be weathered with respect to the global economic climate, especially in European markets. The JP Morgan/GSA Semiconductor Index of Leading Indicators points to a soft semiconductor industry in 2013. However, there are lot of new products in the mobile and tablet space that are driving demand, such as the iPhone 5, Microsoft Surface, and Samsung Galaxy S III.
“The China semiconductor space is emerging as a key market for semiconductor company revenue, and forecasts predict that it will show rapid annual growth rate. The consolidation and M&A activities that we are seeing in the global semiconductor industry also indicate a positive outlook for the upcoming year.
“In India as well, the semiconductor industry will continue to see growth. The injection of funds and other support outlined in the National Policy on Electronics will provide an impetus to home-grown design and manufacturing, which should start gaining traction in 2013.”
Five trends for 2013
What would be the three or five trends likely to be visible in 2013? Ahuja said Cadence sees five big trends that will drive growth in the near and long term. These are: mobility, application driven design, video, cloud and security.
Probably, the most pervasive change in electronics recently has been mobility. When we talk about mobility, it’s just not about smart phones or tablets, but any kind of device which is mobile. Within the mobile space, software applications help system manufacturers and vendors differentiate themselves and stand apart from the competition. The need to have apps on all kinds of devices is driving rapid growth, as well as placing new demands on EDA companies.
The entertainment industry will be the key driver for video, and as the year progresses, we will continue to see more and more products and solutions introduced to tap into the demand. For the semiconductor industry, video will drive growth both in the end consumer market (mobile platforms) and the enterprise space (networking industry).
In many ways, the backbone to mobility is the cloud. With its network servers and infrastructure, the cloud is what delivers much of the content and value to all of those mobile devices. Statistics show that we need one server for every 600 smart phones and one for every 120 tablets. So there is a big need for data centers which can provide support for all the computing and back-end operations.
Security of data in mobile devices and the cloud will continue to be a challenge in the near future. There will be renewed calls to develop products that can protect critical infrastructure and sensitive information from security breaches.

Cadence Design Systems recently introduced the latest release of Cadence Encounter RTL-to-GDSII flow for high-performance and giga-scale designs, including those at the latest technology node, 20 nanometers.
Rahul Deokar, product management director, said: “We are addressing designer challenges in – high performance design, giga-scale design and advanced node design. The first challenge is the PPA – power performance and area. Next challenge is to handle giga-scale designs with efficient turnaround time. The third key challenge is fast time-to-market on advanced 28nm/20nm design.”
With this latest release, Cadence provides the industry’s best PPA. Second, it is providing 1 billion gates on designer desktops. Third, it provides the fastest path to 20nm digital design. In the new announcement, there are three new technologies – GigaOpt + CCOpt, GigaFlex, and 20nm double patterning.
Cadence has introduced “GigaOpt” – a common optimization engine that unifies physical synthesis and optimization. GigaOpt provides designers globally optimal results across the front-end and back-end of the design flow. And that results in the benefit of the industry’s best PPA for high-performance design. GigaOpt has been designed from scratch to be multi-threaded, which makes it ultra fast and ultra scalable.
Another innovation, CCOpt, is the first and only technology in EDA to unify clock tree synthesis and physical optimization. CCOpt is now an integral part of the Encounter flow accelerating design closure with the best PPA. CCOpt facilitates:
* 10 percent improvement in design performance and total power.

The Encounter flow now allows 1 billion gates to be enabled on the designer’s desktops. This is done with the new GigaFlex abstraction technology. It is the first and only technology in EDA that enables flexible, accurate abstraction adaptable to the flow stage. There is 10X capacity and TAT gains on 100 million+ instance designs. GigaFlex abstraction technology allows accurate, early physical modeling, concurrent top-and-block interface optimization, and concurrent hierarchical closure and late-stage ECO. Read more…
While 2011 was generally a year of growth for the global semiconductor industry, 2012 promises to be more volatile, thanks to new macroeconomic issues that will weigh on consumer and IT outlay. The upside is that long-term business trends for semiconductors seem positive, with revenue projected by some industry analysts expected to grow more than twice as fast as global GDP over the next few years.
Global business drivers in 2012
According to Jaswinder Ahuja, corporate VP and MD, Cadence Design Systems (India) Pvt Ltd, the major semiconductor market drivers in 2011 have been apps, video, mobility, cloud computing and green technology, and they will continue to be so into 2012.
As seen over the past year, apps are driving new generations of products. Traditional devices have more functionality than ever before – mobile devices such as smart phones or tablets have the ability to email, tweet, text, browse the web, stream video, take pictures, calendar appointments, and manage your contacts. The pervasiveness of apps are changing the demands on electronic design – this is the basic tenet of the EDA360 vision that Cadence announced in May 2010.
Video drives development of both devices and networks. It is expanding from the television to the smartphone, to media tablets, to your wristwatch. Video is not just used for recreation or entertainment – witness business applications such as videoconferences, surveillance systems, and professional video blogs.
Over the past few years, we have see the consumer’s need for mobility with all their electronic devices – whether a tablet or a gaming console or even in a car. This continues to challenge electronics designers – the need to stay connected all the time is still driving cutting-edge semiconductor design. Along with mobility, we also want long battery life, light weight, small size, and lots of communications options. This, along with the demand for green technology, is a market driver that makes lots of demands on designers. Read more…
The Cadence Executive Forum, titled, ‘Game Changers: New Paradigms for the Future of Electronic Product Realization’, was held this evening in Bangalore, India. The speakers were Lip-Bu Tan, president and CEO, Cadence, and Bhaskar Pramanik, chairman of Microsoft India.
In the opening address, Tan remarked that there is likely to be challenging next 12 months in the USA and Europe. It may also impact the Asia Pacific region. However, from an EDA perspective, there will be new design, as companies would be involved in designing next-generation products and killer applications. There will also be more consolidation, which will continue. Another trend is that the number of start-ups has dropped.
There are two main drivers — technology and market. The cloud is starting to present a big opportunity. Other key areas include green technology and power management. Video will be driving a lot of traffic. The impact on the electronics industry will be new product development, with the IP having expanded beyond processor cores, an increase in collaborations and a changing EDA landscape — Cadence is investing on its decision to deliver the on the EDA360 vision.
Some of the recent highlights include Cadence’s new software development suite that addresses the hardware-software design gap, expansion of the Palladium XP, and releasing the industry’s first DDR4 solution, which includes controller, soft and hard PHY, drivers, verfication IP (VIP) memory models and signal integrity reference designs.
He spoke about horizontal collaborations such as app programing interface, and vertical collaborations, which creates differentiation in the end markets. It also engages foundries in EDA, IP, etc. As an example, Tan spoke of Spreadtrum achieving one-pass silicon realization for the first 40nm product. Some other examples include Samsung designing and implementing 20nm product, ARM and Cadence collaborating on GHz implementation of Cortex-A15, and ARM, TSMC and Cadence collaborating on the industry’s first 20nm Cortex-A15.
Speaking on ‘Consumerization of IT’, Bhaskar Pramanik touched upon consumer trends driving IT. These trends include the economic system of computers, natural interaction, data explosion, social computing, pervasive displays, ubiquitous connectivity, and cloud computing.
According to him, computers will adapt to us. They will enable computing interfaces that are far more easier to use. The key business requirement is to balance the user expectations with the enterprise requirements.
