Hi community,

 

 

We are simulating by the following IBIS file.

  i.MX 6DualLIte and i.MX 6Solo IBIS File(REV 1.4.)

 

Finally, We would like to confirm the signal difference by a simulation and our circuit board.

Therefore, I want to know register setting of IBIS model.

 

In addition information, A reference manual is described as follows.
"66.2.6 Recommended Register Configuration for USB Certification"

  See : i.MX 6Solo/6DualLite Applications Processor Reference Manual (REV 2)   P.5537

 

This is different from register setting of default.

   See : i.MX 6Solo/6DualLite Applications Processor Reference Manual (REV 2)   P.5545

             66.3.2 USB PHY Transmitter Control Register (USBPHYx_TXn)

 

Register field parameterRecommend for USB CertificationDefault value
HW_USBPHY_TX_TXCAL45DP0x00x6
HW_USBPHY_TX_TXCAL45DN0x00x6
HW_USBPHY_TX_D_CAL0x70x7

  

 

What kind of a register setting in IBIS model is it?
