Can HDMI2.1 be implemented using Arria 10 -3 grade FPGA?

Dear,

I know we have HDMI2.1 demo using A10 development kit, can i using this IP on -3 grade devices? like 10AX027H4F34I3G?

Hi, It is recommended to use Arria 10 FPGA device with speed grade 2 or faster. You might facing timing issue if you use Speed grade -3

Hi BoonT，

Thanks.​

How about -2LG？I want to use 10AX066H3F34I2LG.

[BoonT_Intel]

this device speed grade is -2. So it is good to go.

Dear，

​From HDMI UG below，

it recommend -1 for HDMI2.1 and -2，-1 for HDMI2.0，but i have implement HDMI2.0 on A10 -3 device successfully. Is there any risk if i use -2LG?

It is recommended to follow the table. Even you able to see the timing passing. But there still a risk marginal issue on it (even the lower speed grade -3 pass timing). Also, the internal hardware validation is carry on based on the recommended table.
