TMS320C6657: IBIS models for the TMS320C6657 DDR3 controller

 Could you please provide me with the download link to the IBIS model(s) for the TMS320C6657 DDR3 controller? Your sprabi1c.pdf documents states: TI Commitment: Texas Instruments has taken the initiative to provide IBIS models compliant with the latest 5.0 IBIS standard for the DDR3 interface. The Texas Instruments DSP IBIS model will be correlated to internal Matlab or Spice models, and functionally against timing and performance parameters prior to release (TMS).
