Transceiver Pin Assignment for Stratix 4 GX

Hi, i'm the colleague of thomas and i wrote the firmeware.

Here are some additional information about the transceiver configuration.

• Protocol: Basic X4

• Transmitter only

• Effective datarate : 1720 Mbps

• inclk frequency : 430 MHz

• PLL bandwith: Auto

• VCCHTX: Auto

• Pre-emphasis pre-tap: 0

• Pre-emphasis first Post-tap: 0

• Pre-emphasis second post-tap: 0

• Self test mode: none

• low latency PCS mode is enabled

• No reconfiguration and loopbacks

We use the Stratix IV signal integrity development board DK-SI-4SGX230N.

I only want to put out a pulscode of '1010...'. The calibration clock signal is the 100 MHz clock from the development board (PIN_A34, LVDS).

i_tx_ref_clk is connected to the transceiver clock PIN_AN38 (LVDS) and generated by a Rohde&Schwarz SMHU Signal Generator ( 430MHz, sine wave)

    u_tx_channel : tx_channel
      port map
      (
        -- inputs
        cal_blk_clk            => i_tx_calibration_clk,
        cal_blk_powerdown => '0',
        pll_inclk                 => i_tx_ref_clk,
        pll_powerdown        => '0',
        tx_digitalreset        => '0',
        tx_datain               => x"AAAAAAAAAAAAAAAA",
        coreclkout(0)         => memory_clk,
        tx_clkout               => open,
        tx_dataout             => tx_dataout_sig
      );

Now I try to connect to the transceiver via the transceiver toolkit. I load the design and clicked on "Link Instance to device ...." but nothing happened. No Transmitter Channel is displayed.
