DesignWare HBM3 PHY IP

The Synopsys DesignWare® HBM3 PHY is a complete physical layer IP interface (PHY) solution for high-performance computing (HPC), AI, graphics, and networking ASIC, ASSP, and system-on-chip (SoC) applications requiring high-bandwidth HBM3 DRAM interfaces operating at up to 7200 Mbps. The DesignWare HBM3 PHY offers superior power efficiency compared to any other off-chip memory interface and supports up to 4 active operating states enabling dynamic frequency scaling. To minimize area, the PHY utilizes an optimized micro bump array. Support for longer channel lengths allows more flexibility in the PHY placement on the SoC without impacting performance. The PHY provides a complete HBM3 interface solution when combined with Synopsys’ DesignWare HBM3 Controller IP and HBM3 memory model VIP.

The configurable DesignWare HBM3 PHY is provided as a set of hard macrocells delivered as GDSII. These hard macrocells include integrated application-specific HBM3 I/Os required for HBM3 signaling. The design is optimized for high performance, low latency, low area, low power, and ease of integration. The hard macrocells are easily assembled into a complete 1024-bit HBM3 PHY. The RTL-based PHY Utility Block (PUB) supports the GDSIIbased PHY components and includes the PHY training circuitry, configurations registers and BIST control. The HBM3 PHY includes a DFI 5.0-compatible interface to the memory controller, supporting DFI 1:1:2 and DFI 1:2:4 clock ratios. The design is compatible with both metal-insulator-metal (MIM) and non-MIM power decoupling strategies. Synopsys also offers a pre-hardened “drop-in” version of the DesignWare HBM3 PHY for customers that do not have significant custom requirements. For customers that require a custom hard DesignWare HBM3 PHY, Synopsys also offer PHY hardening design services.
