Modify DisplayPort 1.4 RX zcu102 example design for zcu111

[larryhld]

Hi,

I've generated the DisplayPort 1.4 RX zcu102 example design based on the instructions in PG300. Seems like it would be possible to modify the example design to work on the zcu111 given that it has an FMC connector and uses the Znyq UltraSCALE PS. Would this simply be a matter of changing the pin out for the project or is there more to it than that? Also what is the most efficient method to change the pin out and device assignments, can I import the assignments somehow?

I plan to purchase a zcu102 specifically for this project but have a zcu111 for an RF project and am hoping to get a jump start on this effort.

Best Regards,

HI @larryhld 

The first thing you will have to check is if the mapping of the FMC card and the one of the FMC connector are compatible.

Basically you need to check the following:

1. Can you connect the 4 GT channels (i.e. 16 differential pins for RX and TX)
2. can you connect the AUX lanes (in and out)
3. Can you connect the HPD pins (in and out)
4. Can you connect the clock pin

(BTW I haven't check so I cannot say if this is possible)

If this is matching, then you can port the ZCU102 to ZCU111 with the following way:

1. Generate the design for the ZCU102
2. Change the board target to ZCU111
3. Edit the constraint file (xdc) to change the pin mapping to match the ZCU111 board
