DDR5 Implementation Kit

Open Live Script

Implement a 1-slot generic DDR5 RDIMM interface for pre-layout analysis or post-layout verification.

DDR5 is an industry standard dynamic memory format operating at a maximum of 6400M transfers per second. The standard is defined by JEDEC in the DDR5 JEDEC Specification JESD79-5.

This DDR5 implementation signal integrity kit includes all the transfer nets, waveform processing levels and simulation models for a 1-slot generic DDR5 RDIMM interface. This includes buffer models for a generic DDR5 controller, register and SDRAM, along with complete waveform processing levels. You can modify the kit to match your exact DDR5 implementation. Then, perform complete pre-layout solution space analysis and/or full post-layout verification for waveform quality and timing margins.

Kit Overview

  • Project name: DDR5_RDimm_RC_X

  • Interface name: ddr5_1slot

  • Two independent DDR5 channels in the generic controller: DDR5_0 and DDR5_1

  • 72-bits per channel (64 data, 8 ECC)

  • 288-pin buffered DDR5 RDIMM

  • Address/Command 1N timing utilized (can be set up for 2N if desired)

  • Data mask (DM) not used

The slot is populated with Raw Card “X” DDR5 Registered DIMM modules. Raw Card X used for setup and is not a JEDEC specified Raw Card.

  • Number of SDRAMs: 18

  • Package Type: Planar, 78 ball FPGA

  • Number of Ranks: 2

  • Width: x4

This kit supports both HSPICE and IsSpice4 simulators. No specific version of either simulator is required when running this kit.

For more information about the generic DDR5 using a mock Raw Card X RDIMM implementation signal integrity kit, including block diagrams, system configurations, transfer nets and libraries, refer to the document DDR5_RDimm_RC_X.pdf that is attached to this example as a supporting file.
