In the rapidly evolving world of high-performance computing (HPC) and artificial intelligence (AI), technological advancements must keep pace with increasing demands for speed, efficiency, and security. Synopsys recently announced the industry’s first complete PCIe 7.0 IP solution. This groundbreaking initiative addresses current demands and anticipates future needs, highlighting the importance of early access to advanced technology, the benefits of providing a complete solution, and Synopsys’ pivotal role in the industry. I had an opportunity to gain further insights around this announcement, from Manmeet Walia, Executive Director, Mixed-Signal PHY IP at Synopsys.
Meeting the Demands of Modern Data Centers
The demand for computational power in AI and HPC applications is growing at an unprecedented rate. Large language models require the processing of trillions of parameters in real-time. Synopsys’ PCIe 7.0 solution, with its doubled bandwidth of up to 512 GB/s bidirectional in a x16 configuration, is designed to meet these exacting requirements. Early access to this technology is crucial for hyperscalers and AI data centers to stay ahead of the curve, enabling them to handle larger datasets, faster processing, and more complex algorithms efficiently.
One of the standout features of Synopsys’ PCIe 7.0 solution is its support for linear direct drive optics. This technology eliminates the need for additional digital signal processing (DSP) chips within the optical modules, reducing power consumption and latency. By directly interfacing with optical components, Synopsys’ solution enhances signal integrity and performance, making it ideal for high-speed data transfer over longer distances.
PCIe 7.0 Over Cable and Optics
The ability to extend PCIe 7.0 connectivity beyond traditional confines is a significant advancement. Synopsys’ demonstrations of PCIe 7.0 over both cable and optics address different facets of data center interconnectivity. Here is a short video clip of a PCIe 7.x, PCIe 6.x and 224G Over Optics Synopsys Demo from OFC 2024 Conference. PCIe over cable enables efficient communication within a rack, traditionally dominated by Ethernet. On the other hand, PCIe over optics facilitates high-speed, low-latency connections between racks and across data centers, supporting distances of up to 2 kilometers. This versatility is crucial for hyperscalers and AI data centers that need to manage vast amounts of data across distributed systems efficiently.
The Imperative of Early Access and Complete Solutions
The pace of innovation in data centers and AI applications necessitates early access to cutting-edge technology. Synopsys is offering an early access program for its PCIe 7.0 IP solution, set to be available in early 2025. By engaging with early adopters, Synopsys enables leading companies to integrate the latest advancements into their designs ahead of the formal standard ratification, expected by the end of 2025. This early access allows for thorough testing, optimization, and customization, ensuring that when the technology becomes mainstream, it is robust, reliable, and ready for mass deployment.
Synopsys’ complete PCIe 7.0 IP solution integrates a controller, PHY, IDE security module, and verification IP, offering a turnkey solution that addresses every aspect of data transfer needs. This complete package simplifies the integration process for customers, ensuring seamless compatibility and optimal performance. By providing a fully integrated solution, Synopsys reduces risks associated with piecemeal implementations, such as compatibility issues and suboptimal performance.
Synopsys’ Leadership and Industry Influence
With over 20 years of experience in PCIe technology, Synopsys holds a strategic vantage position in the industry. The company has a seat on the PCI-SIG board, giving it a deep understanding of upcoming standards and allowing it to influence the direction of PCIe technology. This insight enables Synopsys to align its IP product development closely with industry needs and standards. Synopsys’ extensive track record, with over 500 wins in PCIe Gen 4 IP solution and nearly as many in PCIe Gen 5 IP solution, underscores the company’s expertise and leadership in the field.
The Significance of Synopsys’ Partner Ecosystem
Synopsys’ PCIe 7.0 solution is further strengthened by robust industry support. Leading companies such as Intel, Astera Labs, Enfabrica, Kandou, XConn, Rivos, Microchip and Samtec have endorsed Synopsys’ technology, recognizing its critical role in advancing AI and data center infrastructure. This highlights the broad industry support for PCIe 7.0 and underscores the collaborative effort required to meet the complex demands of modern computing environments.
Demonstrations at PCI-SIG Developers Conference
Synopsys showcased two significant demonstrations at the PCI-SIG Developers Conference on June 12 and June 13, 2024. The first demo featured Synopsys PCIe 7.0 PHY IP running at 128 Gb/s with OpenLight’s Photonic IC, illustrating the electrical-optical-electrical (E-O-E) TX to RX connection. The second demo demonstrated the PCIe 7.0 Controller IP successfully establishing a root complex to endpoint connection with FLIT transfer. These demonstrations highlight the technology’s capabilities and readiness for deployment, reinforcing Synopsys’ leadership position in the PCIe ecosystem.
