I downloaded both the imx7 and imx7d ibis models off of the website and they only contain models for DDR3/DDR3L/LPDDR3 but do not contain the models for LPDDR2. Do you have IBIS models for the LPDDR2 interface for the iMX7 series?
I confirmed that there are no IBIS models for LPDDR2 on the i.MX7 part. The supported models are included in the IBIS model package, which is available on the NXP website.
