Description

Why do I get an error in MAP for the Hot Plug Detect (HPD) pin, when trying to target a Kintex-7 FPGA?

ERROR:Pack:2503 - The "IOB33" component is not supported in this particular device. 

Solution

This is because the output standard used for HPD is not supported for all Kintex-7 devices.

This will be fixed in the LogiCORE DisplayPort v3.1.



To work around this issue, make the following changes:

UCF:
NET "hpd"               IOSTANDARD = "LVCMOS18";



dport_rx_phy.v,

    //----------------------------------------------
    // Hot Plug Detect
    //----------------------------------------------

    OBUF_LVCMOS18 hot_plug_detect_inst (
        .O (hpd),
        .I (hot_plug_detect)
    )
