2.10.3.2 Step 2: Creating Simulation Topology

The following blocks are extracted from the Sigrity tool. Topology is the same in any tools. The simulation can be carried out in any tool, which supports DDR3 simulation.

The following figure shows the typical topology blocks involved in the DDR3 simulations.

  • SmartFusion2/IGLOO2 IBIS: IBIS model of SmartFusion2/IGLOO2
  • PCB: S-parameter model of PCB file, connector models and DIMM PCB models
  • Connector model: Spice models of connector

  • Memory IBIS: IBIS models of DDR3 memory
