MIG Virtex-6 DDR2/DDR3 - SI Simulation using IBIS


A critical step in verifying board layout guidelines for memory interface designs have been followed is to run signal integrity simulations using IBIS. These simulations should always be run both pre-board layout and post-board layout. The purpose of running these simulations is to confirm the signal integrity on the board.

The ML561 Hardware-Simulation Correlation chapter of the Virtex-5 FPGA ML561 Memory Interfaces Development Board User Guide can be used as a guideline. This chapter provides a detailed look at signal integrity correlation results for the ML561 board, and can be used as an example for what to look at and what you should see. It also provides steps to create a design-specific IBIS model to aid in setting up the simulations.
