Dolphin Integration, a partner in the ENIAC THINGS2DO European FD-SOI project, showcased its achievements with PowerStudio™ during the project final review. Power Studio is Dolphin’s cutting-edge EDA tool for safe Power Regulation Networks implementation.
THINGS2DO, which stands for THIN but Great Silicon to Design Objects, was a 4-year, >€120 million EU project (85% industry-funded) with over 40 partners that just finished up at the end of 2017. The goal was to build a design & development ecosystem for FD-SOI. The project funded and supported the development of major FD SOI-based IPs and ASICs as well as EDA tools. (Another recent THINGS2DO announcement was Dream Chips’ ADAS SoC fabbed in GlobalFoundries’ 22FDX technology — read about that here.)
“Being involved in the THINGS2DO project was an opportunity for Dolphin Integration to start introducing FD-SOI in its automatic design methodologies,” said Frederic Poullet, Dolphin Integration’s CTO (read the press release here). “Dolphin Integration plans to offer a full suite of tools allowing its customers to implement right-on-first-pass Power Regulation Networks.”
The company notes that THINGS2DO also proved that low power consumption makes FD-SOI a perfect fit for IoT and automotive applications. For instance, dynamic control of threshold voltage can be used to compensate for temperature variations, and to drive speed improvements by 200% in ultra-low voltage applications.
Dolphin Integration provides energy efficient IPs and ASIC services dedicated to the low-power application market and supports its internal teams with tailor-made software tools. To address the specific needs of its customers in low-power design, Dolphin developed PowerStudio™, a global solution for the optimization of Power Regulation Networks (PRNet) to be used at an early stage of the SoC design process. In particular, it addresses new design challenges in noise and power supply integrity.
The first module of PowerStudio™ will also embed architecture optimization features at the schematic level, in terms of FoM-based cost optimization, mode management, margin cuts and integrability rate-based risk optimization.
Btw, Dolphin Integration Director Frederic Renoux gave an excellent great presentation at an SOI Consortium event in Nanjing, China last year, entitled Embedding power regulation & activity control networks for best SoC PPA.
Dolphin Integration joined Global foundries’ FDXcelerator™ Program last year (read the press release here) to streamline design in 22FDX®. “Our comprehensive and robust library of voltage regulators, power gating cells and logic modules, enables to deal cost-effectively and securely with power distribution, power gating, power monitoring and power control of any SoC design in 22FDX,” Michel Depeyrot, Dolphin Integration’s Chairman, said at the time. “As connected devices sleep most of their time, users of 22FDX also benefit from our ultra-low power and accurate oscillators to design an always-on RTC which consumes as little as 60 nA.”
12nm FD-SOI has now officially joined the GlobalFoundries’ roadmap, targeting intelligent, connected systems and beating 14/16nm FinFET on performance, power consumption (by 50%!) and cost (see press release here). Customer product tape-outs are expected to begin in the first half of 2019. GloFo also announced FDXcelerator™, an ecosystem designed to give 22FDX™ SoC design a boost and reduce time-to-market for its customers (press release here).
The news turned heads worldwide (hundreds of publications immediately picked up the news) – and especially in China. “We are excited about the GlobalFoundries 12FDX offering and the value it can provide to customers in China,” said Dr. Xi Wang, Director General, Academician of Chinese Academy of Sciences, Shanghai Institute of Microsystem and Information Technology. “Extending the FD-SOI roadmap will enable customers in markets such as mobile, IoT, and automotive to leverage the power efficiency and performance benefits of the FDX technologies to create competitive products.”
Wayne Dai, CEO of VeriSilicon (headquartered in Shanghai but designing for the world’s biggest names in the chip biz), added, “We look forward to extending our collaboration with GlobalFoundries on their 12FDX offering and providing high-quality, low-power and cost-effective solutions to our customers for the China market. The unique benefits of FD-SOI technologies enable us to differentiate in the automotive, IoT, mobility, and consumer market segments.”
The ultra-thin FD-SOI wafers are where it all starts, and they’re ready to go in high volume, says Paul Boudre, CEO of SOI wafer leader Soitec. “We are very pleased to see a strong momentum and a very solid adoption from fabless customers in 22FDX offering,” he adds. “Now this new 12FDX offering will further expand FD-SOI market adoption. This is an amazing opportunity for our industry just in time to support a big wave of new mobile and connected applications.”
GloFo’s 12FDXTM platform, which builds on the success of its 22FDXTM offering, is designed to enable the intelligent systems of tomorrow across a range of applications, from mobile computing and 5G connectivity to artificial intelligence and autonomous vehicles. Increased integration of intelligent components including wireless (RF) connectivity, non-volatile memory, and power management—all while driving ultra-low power consumption—are key 12FDX selling points that FinFETs can’t touch.
The technology also provides the industry’s widest range of dynamic voltage scaling and unmatched design flexibility via software-controlled transistors—capable of delivering peak performance when and where it is needed, while balancing static and dynamic power for the ultimate in energy efficiency.
“Some applications require the unsurpassed performance of FinFET transistors, but the vast majority of connected devices need high levels of integration and more flexibility for performance and power consumption, at costs FinFET cannot achieve,” said GLOBALFOUNDRIES CEO Sanjay Jha. “Our 22FDX and 12FDX technologies fill a gap in the industry’s roadmap by providing an alternative path for the next generation of connected intelligent systems. And with our FDX platforms, the cost of design is significantly lower, reopening the door for advanced node migration and spurring increased innovation across the ecosystem.”
Kudos came in from G. Dan Hutcheson, CEO of VLSI Research, IBS CEO Handel Jones, Linley Group Founder Linley Gwennap, Dasaradha Gude, CEO of IP/design specialists INVECAS, Leti CEO Marie Semeria and NXP VP Ron Martino (they’ve already started on 28nm FD-SOI for their i.MX line – read his superb explanations in ASN here).
Simultaneously to the 12FDX announcement, GloFo announced the FDXcelerator Partner Program. It creates an open framework under which selected Partners can integrate their products or services into a validated, plug and play catalog of design solutions. This level of integration allows customers to create high performance designs while minimizing development costs through access to a broad set of quality offerings, specific to 22FDX technology. The Partner ecosystem positions members and customers to take advantage of the broad adoption and accelerating growth of the FDX market.
Initial partners of the FDXcelerator Partner Program are: Synopsys (EDA), Cadence (EDA), INVECAS (IP and Design Solutions), VeriSilicon (ASIC), CEA Leti (services), Dreamchip (reference solutions) and Encore Semi (services). These companies have already initiated work to deliver advanced 22FDX SoC solutions and services.
Initial FDXcelerator Partners have committed a set of key offerings to the program, including:
Additional FDXcelerator members will be announced in the following months.
From wafers to apps, Leti has been the moving force behind all things SOI for over 30 years. Now they’re the powerhouse behind the FD-SOI phenomenon. CEO Marie-Noelle Semeria shares her insights here in part 2 of this exclusive ASN interview as to what Leti’s doing to drive the ecosystem forward. (In part 1, she shared her insights into what makes Leti tick – if you missed it, you can click here to read it now.)

ASN: In which areas do you see SOI giving designers an edge?
MS: There is an advantage in terms of cost and power, so it’s attractive for IoT, for automotive, and more and more for medical devices. We see the first products in networks, in imaging, in RF. The flexibility of the design, thanks to the back bias gives another asset in terms of integration and cost. We consider that 28nm FD-SOI and 22nm FD-SOI are the IoT platforms, enabling many functions required by IoT applications. It’s a very exciting period for designers, for product managers, for start-ups. You can imagine new applications, new designs, and take advantage of engineered substrates combined with planar FD-SOI CMOS technology and 3D integration strategies to explore new frontiers.
ASN: What is Leti doing moving forward?
MS: Our commitment is to create value for our partners. So what is key for SOI now is to extend the ecosystem and to catch the IoT wave, especially for automotives, manufacturing and wearables. That’s why we launched the Silicon Impulse Initiative (SII) as a single entry gate providing access to FD-SOI IP and technology. SII is a consortium, gathering Soitec, ST, CMP, Dolphin and others, in order to beef up the EDA and design ecosystems. Silicon Impulse offers multi-project wafer runs (MPWs) with ST and GF as foundries based on a full portfolio of IPs. SII is setting up the ecosystem to make FD-SOI technology available for all the designers who have IP in bulk or in FinFET. To reach designers, we have set up events close to international conferences like DAC and VLSI, and we promote SII together with the SOI Consortium in San Francisco, Taiwan, Shanghai, Dresden….
The second way we are accelerating the deployment of FD-SOI technology in manufacturing is to provide our expertise to the companies who made the choice for FD-SOI technology. Leti assignees are working in Crolles with ST and in Dresden with GF to support the development of the technology and of specific IP such as back bias IP. The design center located in the Minatec premises is also open to designers who want to experiment with FD-SOI technology and have access to proof in silicon.
ASN: What role does Leti play in the SOI roadmap?
MS: The role of Leti is to pioneer the technology, to extend the ecosystem and to demonstrate in products the powerful ability of FD-SOI to impact new applications. Leti pioneered FD-SOI technology about 20 years ago. Soitec is a start-up of Leti, as well as SOISIC (which was acquired by ARM) in design. We developed the technology with ST, partnering with IBM, TI and universities. Now we’ve opened the ecosystem with GlobalFoundries and are considering new players. With the Silicon Impulse Initiative we are going a step further to open the technology to designers in the framework of our design center. We have had a pioneering role. Now we have to play a catalyst role in order to channel new customers toward FD-SOI technology and to enable new products.
Leti demonstrates that the FD-SOI roadmap can be expanded up to 7nm with huge performance taking advantage of the back biasing. Leti’s role is to transform the present window into a wide route for numerous applications requiring multi-node generations of technologies.
ASN: Is Silicon Impulse strictly FD-SOI, or do you have photonics, MEMS, RF-SOI…?
MS: We started with FD-SOI at 28nm because it’s available: it’s here. But as soon as the full EDA-IP ecosystem is set-up, this will be open for sure to all the emerging technologies: embedded memory (RRAM, PCM,MRAM…), 3D integration (CoolCube, Cu/Cu), imaging, photonics, sensors, RF, neuromorphic technology, quantum systems….which are developed in Leti. Having access to a full capability of demonstrations in a world class innovation ecosystem backed by a semiconductor foundry and a global IP portfolio leverages the value of SII.
ASN: Can you tell us about the arrangement with GlobalFoundries for 22nm FD-SOI? How did that evolve, and what does it mean for the ecosystem?
MS: Yes, last month we announced that we have joined GlobalFoundries’ GlobalSolutions ecosystem as an ASIC provider, specifically to support their 22FDX™ technology platform. We have worked with GlobalFoundries over the years in the frame of the IBM Alliance pre-T0 program..
In joining the GlobalSolutions ecosystem, Leti’s goal is to ensure that GF’s customers – chip designers – get the very best service from FD-SOI design conception through high-volume production. This has been in the works for a while. At the beginning of 2015, we sent a team to GlobalFoundries’ Fab 1 in Dresden to support ramp up of the platform. And now as an ecosystem partner, Leti will help their customers with circuit-design IP, including fully leveraging the back-bias feature, which will give them exceptional performance at very low voltages with low leakage.
We will be able to help a broad range of designers use all the strengths that FD-SOI brings to the table in terms of ultra-low-power and high performance, especially in 22nm IoT and mobile devices. It really is a win-win situation, in that both our customer bases will get increased access to both our respective technologies and expertise. It’s an excellent example of Leti’s global strategy.

CEO Marie Semeria shares her insights here in part 1 of this exclusive ASN interview as to what makes Leti tick. In part 2, we’ll talk about Leti’s new projects and partnerships.

Advanced Substrate News (ASN): You’ve been CEO of Leti for a little over a year now, but those outside the Grenoble ecosystem are just getting to know you. Can you tell us a little about yourself and how you came to Leti?
Marie Semeria (MS): My background is in physics. I did my PhD at Leti on magnetic memories. Then I joined Sagem in the framework of a technology transfer, followed by a start-up in field-emission display (FED). When I came back to Leti, I spent more than 15 years in different positions, mainly involved in microelectronics. This work included setting up the cooperation with the IBM alliance and technology program coordination, as well as preparing Leti’s future and setting up long-term projects and partnerships.
Then three years ago the CEO at CEA Tech asked me to join that organization. CEA Tech is the technology research unit of the CEA (the French Atomic Energy and Alternative Energy Commission). Leti is one of CEA Tech’s three institutes, which together are developing a broad portfolio of technologies for information/communications technologies, energy, and healthcare. So I extended what I did in Leti covering the whole domain of expertise of CEA Tech. Finally, in October 2014, I took over from outgoing Leti CEO Laurent Malier.
ASN: Can you tell us about Leti’s structure and budget? How are you different from the other big European research organizations?
MS: Leti is a leading-edge research institute. Our mission is to innovate: with industry, for industry. So 83% of our budget comes from partnerships funded by industry, or partially funded by industry and supported by the European Commission or local or national authorities. The other 17% is a grant from CEA. Our commitment is to create value. And so the business model of Leti is value-centric – value for its partners.
ASN: How do you decide what you’re going to work on? Is it your customers?
MS: Leti focuses its work on technological research. We are not an academic lab. We work closely with industry. So we share our roadmap with our industrial partners, which gives us feedback on their expectations, their visions, and helps us anticipate their needs.
On another side, we have to be innovative ourselves, so we are very open to what is going on in the scientific world, sensing new trends, analyzing migrations, monitoring the emergence of new concepts. Therefore, part of Leti’s research is fed by partnerships with academic labs. And there are great opportunities to work with two divisions of CEA related to fundamental research in materials science and in life science. We have a partnership with Caltech in NEMS. We have partnerships with MIT, and with Berkeley in FD-SOI design. It is key for Leti to build on the relationships with the world’s leading international technological universities. We’re fully involved with the very active Grenoble ecosystem. There are great leveraging opportunities within MINATEC and MINALOGIC, with Grenoble-Alpes University and with the INPG engineering school in math and physics. The cooperation with the researchers at LTM is key in microelectronics and we will work with new teams at INRIA who will join us in the new software and design center located in MINATEC.
ASN: How much Leti activity is based on SOI?
MS: SOI is the differentiator for Leti in nanoelectronics. We pioneered the technology 30 years ago and boosted the diffusion and the adoption of the technology worldwide. This year we launched a new initiative named Silicon Impulse together with our partners ST, CMP, and Dolphin…to provide access to the FD-SOI technology and IP to designers. I would say about 50% of the resources of Leti is related to nano: nanoelectronics, nanosystems, nanopower, 3D integration, packaging, with silicon at the core.
All that we have developed in terms of CMOS, embedded memory, RF, photonics and MEMS, is based on SOI. So we’ve developed a complete, fully-depleted (FD) SOI platform for the Internet of Things, because you’ll need all these functions. Really, all the microelectronics activity of Leti has been based on SOI for a while now. It’s why today we continue to pioneer the technology. For example, we develop the substrates and we assess their performance with Soitec in the framework of a joint lab, which is a new strategy for both of us. We work with ST, with GlobalFoundries, to transfer the technology, to prove the substrate in their products. Now we are in a key position as a leading, innovating institute to turn our disruptive technology into products. So it’s really a turning point for us.

Right on schedule, the SFARDS cryptocurrency ASIC on 28nm FD-SOI has made its debut in silicon, and is surpassing expectations. In what is clearly a stunning success, the company announced that the ASIC’s lowest working voltage is 0.45V. This means it operates stably at a power supply voltage that’s about half that of competing 28nm offerings.
An article published on the SFARDS website (see the whole thing here) said, “Using the latest in FD-SOI processing technology, SFARDS has successfully completed its 28nm SF3301 dual-algorithm ASIC chip. The SF3301 is the world’s first chip to use this manufacturing process and is at the same time the world’s first 28nm dual-algorithm (SHA-256 & Scrypt) chip, capable of mining these two algorithms simultaneously or singularly.
“SFARDS’ SF3301 fully utilizes the advantages of the FD-SOI technology. This brings increased forward body bias; the chip is operational at lower voltage while maintaining a higher frequency. The chip boasts impressive power efficiency while affording high hash power, allowing for much lower wastage per hash. The ASIC’s lowest working voltage is 0.45V.”
As noted in ASN’s Buzz in March 2015 (read it here), cryptocurrency (the best-known example of which is Bitcoin) depends on “ledgers” supported by bitcoin “mining” chips. As well-explained in an arstechnica piece (read it here), while some Bitcoin mining is done on CPUs and GPUs, serious mining requires much faster and lower power ASICs in the hardware.
At the time of this post, tape out of the company’s SF3301ASIC has been announced as complete. Cryptocurrency (the best-known example of which is Bitcoin) depends on “ledgers” supported by bitcoin “mining” chips. As noted in an arstechnica piece (read it here), while some Bitcoin mining is done on CPUs and GPUs, serious mining requires much faster and lower power ASICs in the hardware.
As posted on the SFARD blog, “By using FDSOI technology not currently present in any other chip on the market, power efficiency when mining with SHA-256 is predicted to reach below the 0.3 J/GH range, and 2.0 J/MH when mining with Scrypt.
“The SF3301 is extremely versatile, allowing you to mine multiple currencies with one device. This means price fluctuations can be harnessed and being forced to turn off your miner is far less likely.
“A condition can arise where altcoins are utilized to cover electricity costs while bitcoin is continuously and simultaneously being mined. This ability is something never seen before with 28nm technology.”
