About IBIS model of IMX7D

[okamotosatoshi]

Hi There,

I want to check for IMX7 Dual.
I obtained IBIS model for implementing the SI simulation.
 SI:Signal Integrity
Memory uses LPDDR3.

IBIS models has the following two models.
 ・mx7d_12x12_1p8v_lpddr3.ibs
 ・mx7d_12x12_3p3v_lpddr3.ibs

I use IMX7 Dual.
 Device:「MCIMX7D7DVM10SC」

Do you have a model of 19x19?

Best regards

Hello,

Please refer to Table 27 (IBIS Model naming convention) of the Hardware Development Guide

http://www.nxp.com/files/32bit/doc/user_guide/IMX7DSHDG.pdf?fasp=1&WT_TYPE=Users%20Guides&WT_VENDOR=... 

Different IBIS files relate to different GPIO supply voltages NVCC_xxx.

Have a great day,
Yuri

Hi There,

Sorry, Model was incorrect.

19x19 model was available.

I want to check for IMX7 Dual.
I obtained IBIS model for implementing the SI simulation.
 SI:Signal Integrity
Memory uses LPDDR3.

IBIS models has the following two models.
 ・mx7d_19x19_1p8v_lpddr3.ibs
 ・mx7d_19x19_3p3v_lpddr3.ibs

How should used properly of model ?
Should I change the model in the case of somewhere voltage 1.8V or 3.3V ?
