The Ultimate Chiplet System

The Ultimate Chiplet Interconnect. Period.

Eliyan’s Interconnect technology built with standard organic chip packaging delivers the same performance as advanced packaging technology, and enables The Ultimate Chiplet Systems at a fraction of total cost of ownership. Without the downsides of advanced packaging, you achieve higher number of cores, compute performance, test coverage, and yield.


The transition from monolithic chips into discrete chiplets results in more powerful systems. And the industry is no longer depending on Moore’s Law to provide a path to higher performance, and lower energy at a reasonable cost and complexity. The race to chiplets has put the spotlight squarely on interconnects. Chiplet configurations require new technology optimized to deliver high bandwidth, low latency, and low power. Today, the Universal Chiplet Interconnect Express (UCIe) specification has defined these interconnects, enabling an open ecosystem and ubiquitous interconnect at the package level.

That’s where Eliyan comes in. NuLink™, the Eliyan interconnect solution, delivers performance and power/area efficiency that no other technology can offer. Our exclusive trade secrets and patent-protected technologies deliver a UCIe compliant interconnect at twice the bandwidth and half the power.

How is this possible? Because we have been at this for years, long before the industry standards were established. Inventing NuLink technology, incrementally improving it over the years, and taking it to volume production, have enabled us to achieve unprecedented characteristics.

“The economics of adopting a chiplet approach for IC design are tightly linked with the cost and maturity of the interconnect and packaging solution, as we demonstrated in our analysis. Eliyan’s chiplet interconnect technology will make multi-die approaches more attractive to chip suppliers whose designs must optimize on power and bandwidth vectors. This is especially the case for those in accelerated server computing applications, a market mainly served by datacenter GPU hardware, and which we see sustaining a 22% unit growth CAGR through 2028.”


Pioneering BoW

A Breakthrough Die-to-Die Interconnect

In 2018, Eliyan CEO Ramin Farjadrad proposed Bunch of Wires (BoW), a superior chiplet interconnect architecture based on NuLink, at the Open Compute Project (OCP). The NuLink architecture leveraged cross-technology innovations to deliver the highest bandwidth and lowest latency, at best-in-class area and power efficiency. Given the exceptional performance and features of BoW, it received strong support at OCP and was later adopted as the chiplet interconnect of OCP on organic substrates as well as advanced packaging. Nulink technology not only led to creation of BoW at OCP, but the signaling/clocking scheme and PHY architecture also became the foundation for UCIe, which is proposed and adopted by a broad cross-section of industry heavyweights. Given the history of Nulink and its myriad similarities with UCIe, Eliyan is on the fastest path to the highest-performance UCIe compliant interconnect.
