can XC7K325T use hdmi 2.0 ip in MGT116?

[autelchengpeng]

we use hdmi2.0 ip on the MGT116 of xc7k325T, but we find that HDMI on xc7k325T cann't change MGT pin.

can XC7K325T use hdmi 2.0 ip  in MGT116? if it can, how to change pin form MGT118 to MGT116?

Hello @autelchengpeng

Your Video PHY controller pin assignment is controlled by XDC file.

Please find the following lines on your FPGA design constrain file (XDC), then modify the pin assignment accordingly.

set_property PACKAGE_PIN ** [get_ports {HDMI_TX_DAT_P_OUT[?]}]
set_property PACKAGE_PIN ** [get_ports {HDMI_RX_DAT_P_IN[?]}]

Thanks & regards

hello,

     i change pin xdc to mgt116, for below show,  more information see attchment file.

# HDMI RX
#FMC_HPC_GBTCLK0_M2C_C_P
set_property PACKAGE_PIN N8 [get_ports HDMI_RX_CLK_P_IN]

#FMC_HPC_DP2_M2C_P
set_property PACKAGE_PIN P6 [get_ports {HDMI_RX_DAT_P_IN[2]}]

but vivado2016.4 error create,  it change pin fail.

i think XC7K325T cann't change hdmi pin to mgt116, we must use example's mgt118. isn't it?

Hello  @autelchengpeng

What is the device package you are using ?
I do not know the device model you are  using. ( I am assuing XC7K325T-FFV900 )
-- It would be better if you can share your Exact device model/Vivado version/XCI file
   so Forum Moderator can give you an accurate advice.

I looked at the screenshots you have uploaded.
1. You are using QPLL for both TX and RX. Do you have a special reason using this setting ?
    I believe this  is not allowed. Please see PG230 Chapter 3.
2. I cannot see the pin assignment of your HDMI TX pins.
    Do you assign all of the following pins correctly ?

   set_property PACKAGE_PIN ** [get_ports {HDMI_TX_DAT_P_OUT[*]}]
   set_property PACKAGE_PIN ** [get_ports {HDMI_TX_DAT_P_OUT[*]}]
   set_property PACKAGE_PIN ** [get_ports {HDMI_TX_DAT_P_OUT[*]}]
   
Thanks & regards

because of base on  the hdmi2.0 example of kc705, i only change the pin in xdc,  in the example of hdmi, only fixed RX pin. 

so i am also use  XC7K325T-FFV900 , and  use  CPLL for TX and QPLL for RX, and change rx's pin in the xdc. 

i can't change MGT bank, but if i use fpga's xkcu040, i can change Bank. so i think XC7K325T's hdmi only use MGT118.

Hello @autelchengpeng

1. I am not sure if I can understand you correctly.
   Please let me check my understanding.
   
 You are creating a FPGA design based on HDMI Example Design targeting KC705.
 You keep the HDMI TX pin assignment as is ( on MGT118).
 but you only changed RX pin assignment to MG116.
    
  Is my understanding above correct ? (Then it might not worked)

2. Xilinx IP wizard has a slightly different behavior when targeting different device.
   When you are targeting 7-series. You cannot set the GT location from IP GUI.
   This is expected behavior. So corresponding pin assignment constraint must be added in the top-level XDC for designs targeting 7-series

    
Thanks & regards
Leo

Hello karnanl

    Yes, what you understand is right, but i add TX pin assignment to MG116, it is the same error。

the error picture is below:

so it is not error of TX pin assignment to MG116, i think maybe the hdmi ip in the xc7k325t have specail problem.

HI @autelchengpeng,

Are you still using the same clock as in the example design or did you change his pin as well?

You need to follow the correct ruler for the GTs and assign the clock properly. If the clock is coming from the same quad as you GT you can use the basic MGTCLK port . If it is coming from an adjacent quad (south or north), you need to use the advanced clocking mode in the video phy. Also this imply that your clock needs to be coming from the GT quad or from an adjacent quad.
