Unbuffered DDR3 Architectural Kit

Implement an unbuffered DDR3 interface for pre-layout analysis or post-layout verification.

This unbuffered DDR3 architectural signal integrity kit includes all the transfer nets, timing models, waveform processing levels and generic models for an unbuffered DDR3 interface. This includes generic buffer models for the DDR3 controller and SDRAM, along with fully functional timing models and complete waveform processing levels. You can modify the kit to match your exact implementation. Then, perform complete pre-layout solution space analysis and/or full post-layout verification for waveform quality and timing margins.

Open Unbuffered DDR3 Kit

Open the unbuffered DDR3 kit in the Parallel Link Designer app using the openSignalIntegrityKit function.

openSignalIntegrityKit("DDR3_UBuff");

Kit Overview

For more information about the unbuffered DDR3 architectural signal integrity kit, including block diagrams, system configurations, transfer nets and libraries, along with instructions on how to customize the kit for a specific implementation, refer to the document DDR3_Unbuffered.pdf that is attached to this example as a supporting file.
