3.3. Adding the TTTech TSN IP to the Qsys system

You build the TSN system within the TSN drive-on-chip design based on TTTech TSN IP.
  1. Copy the directory ip-sol-scv-release-2.3.0-30_03_2021\de_ip_solution_scv to <Quartus_Project>/ip and ip-sol-scv-release-2.3.0-30_03_2021\de-eval-board\fpga\misc_ip to <Quartus_Project>/ip.
  2. In Qsys, click Tools > Options and add the newly copied directories to the IP search paths.
    Qsys automatically adds the TTTech IP to the IP catalog in the left upper corner of Qsys.

  3. Navigate to ip-sol-scv-release-2.3.0-30_03_2021\de-eval-board\fpga and open de-eval_scv.qar with Intel Quartus Prime.
    The design opens including a Qsys system. The blocks in this design are identical to the ones in the TTTech Reference Design.
  4. In the Qsys system add the following functional blocks and connect them in the same way as the TTTech Reference Design.

    irq0-ir115 0-15
  5. Connect the TSN blocks with a 100 MHz clock from the drive-on-chip subsystem.
  6. Add another Altera PLL block with the same 50 MHz reference clock as input (the same reference clock as the PLL for the drive-on-chip subsystem)
    This additional 125 MHz clock is for the TSN IP m_dma_0_clk port.
  7. Configure the TSN IP with these parameters:
    • Options: LED_ACTIVE 0, Enable link LED interface (turn off)
    • Adapters: Port 0 interface type DMA, Port 1 Interface Type MII, Port 2 Interface Type MII.
  8. Keep the multiple PIO blocks in the TTTech TSN IP Reference Design Qsys System and change the equivalent to pio_phy_reset (pio_0).
    Keep the other PIO modules such as pio_led_debug, pio_pps_debug_out and pio_pps_debug_in.
  9. Configure the HPS module, even though the HPS and the secondary modules are connected in the same way as the TTTech TSN IP Reference Design Qsys system.
    The HPS within the Cyclone V SoC Development board is connected to a different DDR3 memory than the TTTech Reference Board.

Both the drive-on-chip and TSN subsystems now work separately.
