How can I use the HDMI Tx port on Arria V GX Starter kit?

Hi all,

I wanted to use the HDMI Tx port on Arria V GX Starter kit, so I declaired the TMDS output pins and assigned the pins as:

HDMI_TX_CLK_P: PIN_AC3, 1.5-V PCML

HDMI_TX_CLK_N: PIN_AC4, 1.5-V PCML

HDMI_TX_P0: PIN_AJ3, 1.5-V PCML

HDMI_TX_N0: PIN_AJ4, 1.5-V PCML

HDMI_TX_P1: PIN_AG3, 1.5-V PCML

HDMI_TX_N1: PIN_AG4, 1.5-V PCML

HDMI_TX_P2: PIN_AE3, 1.5-V PCML

HDMI_TX_N2: PIN_AE4, 1.5-V PCML

However, when I compiled the design, it showed:

"Error (14566): The Fitter cannot place 4 periphery component(s) due to conflicts with existing constraints (4 pin(s)). Fix the errors described in the submessages, and then rerun the Fitter. The Intel FPGA Knowledge Database may also contain articles with information on how to resolve this periphery placement failure. Review the errors and then visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number."

How can I solve this problem?

Can I use this port without INTEL HDMI IP?

Thanks.

Timmy

    Hi,

    I used NIOS II Command Shell and executed quartus, then opened the project.

    I generated the example again.

    Finally, I had generated the example codes.

    Thank you so much.

    Hi Sir,

    For HDMI in AV GX kit, you may refer to the available example design that can obtain from this document.

    https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_hdmi.pdf#page=47

    Please note that the section also guide you on how to generate the design. You may refer to the design on how to fit the HDMI IP in quartus.

    Also, the port that you listed is transceiver port. You suppose can use it without HDMI IP for other reason.

      Hi,

      When I used the Quartus version 18.1 standard to generate the example code, I got the error message like this:

      How can I solve this error?

    Hi From the error message, looks like there is an issue from the Temp folder.

    Please check if your Temp folder is read-only access.

      It can only use the example code with Intel IPs.

      I gave up and use Xilinx FPGA. 😅

      Although, There was the same issue on Xilinx FPGA. We can’t rewrite the HDMI port without the IPs.
