Hello @haoboy 

Because MIPI D-PHY is only designed for US+ and 7-series devices.
But unfortunately, 7-series SelectIO and UltraScale device SelectIO has different architecture.

I would recommended UltraScale+ devices for a new project using MIPI IPs.
If your project has a limited budget, 7-series can do.

 

Thanks & regards
Leo

Hi @haoboy 

You could design your own D-PHY but there is no solution from XIlinx.You will need an external phy as for 7-series but Xilinx cannot give you nay advise on this as we haven't characterized it.

Discuss with you FAE about moving to US+

You might wanto to ask also our partner NWL to see if they have any solution

Hello @haoboy 

I don't understand your question very well, but I do compelety agree with  @florentw  ,
You can design your own IP using UltraScale SelectIO , but  MIPI D-PHY IP direct migrating from 7-series to US is not possible.

hello @karnanl 

Thanks, what i'm prepare to do is designed our own DPHY using Ultrascale SelectIO.

According the message of you guys, i know this method is doable.

 

BTW, i think the soluion on Ultrascale will simalr to than on 7series, i'm wondering can you guys share me some design spec of you MIPI D-PHY IP on 7 series, it will be a best reference.  I konw there is a pg202, but it's just a userguide of MIPI D-PHY IP.

 

Regards

HI @haoboy 

We cannot share the spec for MIPI. You have to become a MIPI adopter to get the spec.
