Synopsys Accelerates Cloud Computing SoC Designs with New Die-to-Die PHY IP in Advanced 7nm FinFET Process

29 October 2019

MOUNTAIN VIEW, Calif., Oct. 29, 2019 /PRNewswire/ -- Highlights:

  • Ultra-low power DesignWare Die-to-Die PHY IP delivers less than 1pJ/bit for optimal energy efficiency in hyperscale data centers
  • Compact analog front-end enables reliable links up to 50 millimeters for large multi-chip module designs
  • Flexible architecture enables partitioning of the core logic across multiple dies with extremely low-latency and bit error rate
  • Combined with the DesignWare 112G/56G Ethernet, HBM2/2E, DDR5/4, and PCI Express 5.0 IP, Synopsys provides a comprehensive solution for high-performance computing and networking SoCs

Synopsys, Inc. (Nasdaq: SNPS) today announced its DesignWare® Die-to-Die PHY IP for ultra- and extra-short reach connectivity in multi-chip modules (MCM) for hyperscale data center, AI, and networking designs. The DesignWare Die-to-Die PHY IP supports NRZ and PAM-4 signaling from 2.5G to 112G data rates, delivering maximum throughput per die edge for large MCM designs. To improve SoC yield, the Die-to-Die PHY allows for partitioning of large dies into smaller dies while offering trade-offs for power, bandwidth per beachfront, latency, and reach. The DesignWare Die-to-Die PHY is the latest addition to Synopsys' comprehensive cloud computing IP solution consisting of silicon-proven 112G/56G Ethernet HBM2/2E, DDR5/4, and PCI Express 5.0 controller, PHY, and verification IP.

Synopsys provides designers with a comprehensive routing feasibility analysis, packages substrate guidelines, signal and power integrity models, and crosstalk analysis for fast integration of the DesignWare Die-to-Die PHY into SoCs. The half-duplex transmitter and receiver in a X16 lane configuration delivers 1.8 terabit-per-second per millimeter unidirectional bandwidth for high throughput die-to-die connectivity. To meet the power requirements of SoCs in advanced FinFET processes, the Die-to-Die PHY delivers less than one picojoule per bit (pJ/bit) for ultra-low-power die-to-die and die-to-optical engine connectivity. The DesignWare Die-to-Die PHY IP is compliant with the OIF CEI-112G and CEI-56G standards for ultra-short reach (USR) and extra-short reach (XSR) links.    

"Advanced SoCs for high-end data center and networking applications are reaching maximum reticle size limits, requiring designers to partition the SoC into smaller modular dies," said John Koeter, vice president of marketing for IP at Synopsys. "The DesignWare Die-to-Die PHY IP with leading power, performance, and area is enabling our customers to meet their short reach connectivity requirements in designs for the most advanced FinFET processes and deliver differentiated products to the market quickly."


The silicon design kit for the DesignWare Die-to-Die PHY IP in 7nm FinFET process is available now.
