LogiCORE MIPI D-PHY v4.1 (Rev. 4): IDELAYCTRL_RDY is not used in MIPI in FIXED mode

Description

In Vivado 2019.1.1, I have LogiCORE MIPI D-PHY RX IP example code generated with the calibration mode set to FIXED.

However in the synthesized schematic IDELAYCTRL_RDY is not used (it is not connected).

In the MIPI D-PHY RX IP example code generated in Vivado 2019.1.1 with calibration mode set to AUTO, it is used to reset IDELAY.

 

Solution

This is a known issue for the MIPI D-PHY IP, which only affects 7 Series devices:

 
  • Vivado 2019.1.1 - Users can download the MIPI D-PHY IP patch from (Xilinx Answer 72758) to work around this issue.
  • Vivado 2019.2 - This issue is resolved in the MIPI D-PHY v4.1 (Rev. 4) in Vivado 2019.2 and later.
