3.5. Hardware Test for System Console Control Design Example

Perform the following instructions to run the hardware test for the design example using the system console control in the Quartus® Prime software.
Note: This hardware test assumes that you configured your design in duplex mode for system console control. Make your own modifications if you're using simplex mode design.
  1. Launch the System Console tool from Quartus® Prime (Tools > System Debugging Tools > System Console).
  2. In the TCL Console command prompt, type get_service_paths master to print a list of devices connected to your JTAG chain.
  3. Open the main.tcl script located in the ed/hwtest/ directory in any text editor of your choice and locate the following line. 
    set master_index [expr {$master_list_length - 1}]
  4. Adjust the master_index offset as necessary to reflect your JTAG chain configuration such that the master_index always points to the Agilex™ 5 device and save the file.
    Figure 11. Example of master_index Configurations to Reflect JTAG Chain
  5. In the TCL Console command prompt, navigate to the ed/hwtest/ directory (cd../ed/hwtest/) and execute the main.tcl script (source main.tcl).
  6. Type start_basic_test at the command prompt to execute the link setup and test procedure.

    This procedure executes a set of instructions to set up sysref on TX and RX as periodic, check PRBS pattern, configure the GTS JESD204C IP PHY internal serial loopback mode and report link status.

    The following figure illustrates the expected result from a successful link setup and test for a variant of L=2, M=8, and F=12 with a data rate of 17.16 Gbps.
    Figure 12. Successful Test in the System Console
    Table 20.  Procedures in the main.tcl System Console Script The table describes useful procedures in the main.tcl that may be helpful in debugging.
    Procedure Values Description
    get_service_paths {master} Reports all devices that are connected to the JTAG chain. Use this information to set the master index to point to the Agilex™ 5 device.
    get_master_index N/A Sets the targeted device master index. Use get_service_paths master to determine the offset of the Agilex™ 5 device in the JTAG chain, and edit the offset in this procedure accordingly.
    start_basic_test N/A Procedure that executes a set of instructions to set up SYSREF on TX and RX as periodic, check PRBS pattern, configure the GTS JESD204C IP PHY internal serial loopback mode, configure PMA and to report link status.
    reset N/A Global reset
    xcvr_lpbk {0,1}

    0: Disables internal serial loopback

    1: Enables internal serial loopback
    testmode {ramp, prbs7, prbs9, prbs15, prbs23 }

    ramp: Sets pattern generator and checker to ramp pattern

    prbs7-23: Set pattern generator and checker to the respective PRBS patterns
    sysref_type {oneshot, periodic, gperiodic } Sets the SYSREF type
    eval_test N/A

    1. Loads status.

    2. Checks lane by lane.

    3. Shows the TX and RX registers values:

    • rst_sts0:
      • Bit 0 – CORE PLL LOCKED
    • rx_status3:
      • Bit 0-15 – RX CDR LOCKED
    • rx_status4:

      • Bit 0-15 – SH LOCKED

    • rx_status5:
      • Bit 0-15 – EMB LOCKED
    • tst_err0:
      • Bit 0 – PATTERN CHECKER ERROR
      • Bit 1 – TX LINK ERROR
      • Bit 2 – RX LINK ERROR
      • Bit 3 – COMMAND PATTERN CHECKER ERROR
    read_err_status N/A Reads GTS JESD204C IP error status registers.
    clear_err_status N/A Clears GTS JESD204C IP error status registers
    read_rx_status0 N/A Reads GTS JESD204C IP rx_status0 register.
    read_tx_status0 N/A Reads GTS JESD204C IP tx_status0 register.
    read_rx_syncn_sysref_ctrl N/A Reads GTS JESD204C IP syncn_sysref_ctrl register.
    wait_seconds {integer} Waits for {integer} seconds.
    wait_minutes {integer} Waits for {integer} minutes.
