2.10.3.3 Step 3: Simulation Setup

  • Assign IBIS models to SmartFusion2/IGLOO2 and memory
  • Assign connector model if used
  • Assign the models for on board termination resistors

  • Identify the DDR3 nets and classify according to data, control, and address bus

  • Keep the appropriate ODT for SF2 and memory

  • Keep the 40 to 60 Ω ODT for data and 80 Ω to 120 Ω for DQS

  • Set the maximum frequency at which the system will operate (For SF2, it is 333 MHz).
