Chelsio Adopts Synopsys DesignWare 56G Ethernet PHY IP to Accelerate Development of High-Performance Computing SoC
Silicon-Proven 56G Ethernet PHY Delivers True Long Reach Performance with Flexible Data Rates and Low Latency

MOUNTAIN VIEW, Calif., Aug. 27, 2020 /PRNewswire/ --


  • Chelsio selected Synopsys' DesignWare 56G Ethernet PHY IP to accelerate development of its high-speed Ethernet adapter targeting smart NIC and server applications
  • The DesignWare 56G Ethernet PHY with optimized floorplan supports PAM-4 signaling and high-performance algorithms for reliable Ethernet links
  • Continuous calibration and adaptation algorithms deliver robust performance across voltage and temperature variations for operation in harsh conditions

Synopsys, Inc. (Nasdaq: SNPS) today announced that Chelsio has adopted its silicon-proven DesignWare® 56G Ethernet PHY IP to accelerate development of Chelsio's System-on-Chip (SoC) design targeting high-performance smart network interface card (NIC) and server applications. Chelsio selected the Synopsys DesignWare 56G Ethernet PHY IP due to its support for a wide range of data rates from 1.25 Gbps to 56 Gbps across standards such as Ethernet, PCI Express, OIF, and JESD. The DesignWare 56G Ethernet PHY with firmware-controlled algorithms including continuous calibration and adaptation (CCA) delivers robust performance across a range of voltage and temperature variations.

The Ethernet verification IP and source code test suites enable the design and verification of SoCs with ease-of-use and optimum performance, resulting in accelerated verification closure. To speed development of high-performance computing SoCs, Synopsys provides companies like Chelsio with the industry's most comprehensive IP solutions, including 56G and 112G Ethernet PHYs, DDR5, PCI Express 5.0, die-to-die USR/XSR and HBI PHYs, Compute Express Link (CXL), and CCIX. 

"Our next-generation high-speed Ethernet interconnect SoCs used for networking and storage in hyperscale data centers, required mature IP solutions with a flexible and scalable architecture," said Kianoosh Naghshineh, CEO, Chelsio Communications. "After an extensive evaluation process, we chose Synopsys' silicon-proven DesignWare 56G Ethernet PHY IP because it gives us the most reliable reach and performance advantages we needed to meet our high-performance design requirements."

"The significant growth in cloud computing workloads is driving new SoC architectures for compute, storage, and networking applications," said John Koeter, senior vice president of marketing and strategy for IP at Synopsys. "By providing designers with most essential and trusted IP for high-performance computing SoCs, Synopsys is helping companies such as Chelsio address the performance, latency and memory requirements of their designs and quickly get their products to market."
