Proven over time, trusted every time

The fast, reliable way to take your ASIC or ASSP from conception to production.

Since 2000, eSilicon has specialized in designing, productizing, and manufacturing ASICs for our customers: system original equipment manufacturers (OEMs) and fabless semiconductor companies (FSCs).

Our strength is in developing and delivering complex chips. We develop an average of 20 new chips per year, which keeps our skills at the cutting edge. We have delivered first-time-right silicon across over 250 tapeouts at 28nm-250nm.

Fast path to silicon

Accelerated design, custom IP, and a proven production process for first-time-right ASICs and ASSPs.

Our flexible engagement model allows customers to hand off their design at a variety of levels — or engage strictly for custom memory IP. OEMs typically engage at the RTL or netlist level, while FSCs typically engage at the GDSII or production level.

We are structured to support our customers with three engagement models, best-in-class supply chain partners and our proprietary infrastructure.

  • For traditional ASIC development and production, our ASIC engagement model manages the process, from deploying in-house expertise in modeling and helping you choose the ideal set of third-party or custom IP for your design; to test engineering and yield management; through predictable, on-time delivery of your final chip in volume.
  • For customers with proven chips who want to focus on their core business — rather than operations — our Semiconductor Manufacturing Services (SMS) engagement model is the answer. We will take your tested, production-ready chip and manage your volume production.
  • Our IP offering supports both the ASIC and SMS engagement models, as well as independent engagements with customers, to supply an array of 28nm-180nm silicon-proven custom memories, including Cache, CAM, SRAM, ROM, and MPRF, as well as third-party IP.
  • We partner with top suppliers to deliver your design all the way through volume production and delivery.
  • The patented eSilicon Access® production management system is a unique web interface that delivers instant access to critical work-in-process (WIP) supplier, materials and status information.

Whichever path you choose, we’ve built a proven system to take your design to volume production.

Engagement Levels

Vision + Accuracy

Combining the art and science of chip design.

The vision? Create a new semiconductor design and manufacturing solutions (SDMS) business model to:

  • Optimize the economics of customer value chains
  • De-risk IP selection, DFT (design for test) assessment, package/substrate design, and chip implementation by utilizing domain-specific experts
  • Enable customers to focus on their product differentiation and market growth — not operations
  • Earn revenue by shipping packaged, tested products with the customer’s logo

The accuracy? A finely tuned production machine that delivers a consistently first-time-right chip.

Value Chain Producer Business Model

Value Chain Producers
A VCP is a company that collaborates with foundries, IP and service providers, EDA suppliers, and package, assembly and test operations in designing and producing chips for fabless IC, IDM and OEM companies. VCPs optimize the economics of customer value chains and enable customers to focus on their product differentiation and market growth.

eSilicon, the largest independent semiconductor VCP, delivers ASICs to OEMs and fabless semiconductor companies through a fast, flexible, lower-risk path to volume production by deploying its comprehensive suite of design-through-manufacturing services and custom IP offerings. eSilicon serves a wide variety of markets including the communications, computer, consumer, medical and industrial segments.

Real-time supply chain management

Predictable, industry-leading quality with a clear path to cost reduction.

Matching Customers’ Designs with the Right Suppliers
We evaluate suppliers selectively based on their technology, simulating the performance of each element in the supply chain for optimal performance and reliability for each customer’s design.

We are independent and free to work with any foundry or IP supplier. We explore tradeoffs in all dimensions to help customers find the right solution for each design:

  • Process/foundry
  • Die/package
  • Standard IP/custom IP

Close Partnerships Pay off During Tough Times
Close, long-term relationships with our suppliers mean we can act quickly and effectively against adverse industry conditions, such as the 2010 materials shortage and the 2011 catastrophe in Japan.

Multi-Pronged Approach to Cost Reduction
We help our customers achieve significant cost reductions in a variety of ways. Obviously, aggregating volumes is one part of cost reduction. But understanding the underlying technology and removing inefficiencies, as well as advanced test and design methodologies deliver even greater savings. Some of these methodologies include:

  • Concurrent design
  • Design for test (DFT)
  • Design for yield (DFY)
  • Design for manufacture (DFM)
  • IP integration to optimize for power, performance, and area (PPA)

California Transparency in Supply Chains Act (SB 657)

Global company. Local support.

Expert support, where and when you need it
ASIC design is a high-touch business; you need access to the right people with the right expertise in your time zone. As a truly global VCP, we deliver quality support where and when you need it. Whether you need access to our top engineering talent or a local interface to our supply chain partners, eSilicon is there.

We are headquartered in the heart of Silicon Valley in Sunnyvale, California. Our design centers are located in Allentown, Pennsylvania; Murray Hill, New Jersey; Shanghai, China; Ho Chi Minh City and Da Nang, Vietnam; Bucharest and Iasi, Romania; and Barcelona, Spain.

Confidence, results, success

The fast, reliable way to take your chip from concept to volume production.

We’ve built a company focused on bringing you first-time-right ASICs. What are the top five reasons our customers choose eSilicon?

eSilicon is an independent VCP, free to work with any foundry or IP supplier. That means we can explore tradeoffs in all dimensions (process/foundry, NRE/ASP, die/package, standard IP/custom IP) to offer the right solution for each customer’s design.

Lower Total Cost of Ownership (TCO)
A VCP earns margin by eradicating inefficiencies throughout the process and the supply chain to deliver a low TCO. Many of our customers are paying less for their ASICs now than they were when they were doing everything themselves.

Advanced Integrated Methodology Delivers Reduced Risk, Fast Time to Market
Our advanced methodology integrates knowledge of previous designs and state-of-the-art technologies to provide optimum results in new designs, even for the most complex chips.

Custom Memories
With embedded memory occupying more than 50 percent of a typical chip, custom memories can optimize a design for power, performance and area (PPA). We offer a wide selection of 28nm-180nm silicon-proven custom memories, including CAM, Cache, SRAM, ROM and MPRF.

Concurrent Approach
Concurrent die and package design helps us determine the right set of libraries and IP for improved performance and manufacturability without wasted iterations.
