Introduction

This is the full howto to make an APF6_SP CycloneV example design to use :

  • PCIe
  • DDR3
  • LED
  • Button

This howto is designed for :

  • APF6D_SP-M1GE4G-4m-BW-C4M384: APF6_SP Dual with CycloneV C4 (speed C8) and two DDR3 chips
  • Quartus 15.1.1 : Quartus 15 with update 1
The full design for this howto

To install quartus 15 see this page.

Make the quartus project

  • Open the new project wizard in Quartus
  • Select a directory for the design:
~/tmp/apf6_the_full_howto
  • Open an empty project
  • Change the device : right click on "Cyclone V"->Devices... in Project Navigator
  • Select the part number : 5CGXFC4C7U19C8 then Ok

Make the Qsys project

  • Open Qsys: Tools->Qsys
  • Delete the component clk_0 then save the Qsys project with name : qsys_tfht.qsys
  • Clic on finish and generate the component with all options left by default
  • Under Quartus project add the Qsys project (don't forget to click on add after selected here.
How to add a file in project
  • Relaunch Qsys by double-click on the file in project navigator

Adding the PCIe and CvP

  • In IP Catalog select the component:
Library
    Interface Protocols
        PCI Express
            Avalon-MM Cyclone V Hard IP for PCI Express
  • PCIe configuration:
    • Number of Lanes: x1
    • Reference clock frequency: 125Mhz
    • check "Use 62.5 MHz application clock"
    • BAR0: 32-bit non-prefetchable memory
    • BAR1: 32-bit non-prefetchable memory
    • BAR2: 32-bit non-prefetchable memory
    • Vendor ID: 0x00001172
    • Device ID: 0x0000e001
    • Class Code: 0x00001300: there is a bug in quartus, the actual class code is here 13
  • click on finish
  • Export these signal with name in bold:
    • refclk : refclk
    • npor: npor
    • hip_serial: hip_serial
  • connect Rxm_BAR0 on Cra
  • Adding CvP component reconfig driver, with all default parameters:
Library
    Interface Protocols
        PCI Express
            Altera PCIe Reconfig Driver
  • Connect these signals:
    • coreclkout -> reconfig_xcvr_clk
    • coreclkout -> pld_clk
    • nreset_status -> reconfig_xcvr_rst
  • Adding CvP component transceiver, with all default parameters:
Library
    Interface Protocols
        Transceiver PHY
            Transceiver Reconfiguration Controller
  • Connect these signals:
    • coreclkout -> mgmt_clk_clk
    • nreset_status -> mgmt_rst_reset
    • reconfig_mgmt -> reconfig_mgmt
    • reconfig_driver.reconfig_busy -> reconfig_busy
    • pci.reconfig_to_xcvr -> reconfig_to_xcvr
    • pci.reconfig_from_xcvr -> reconfig_from_xcvr
Wiring result after PCIe configured


Adding the DDR3

Note Note: When parameters should be left by default they are not indicated


UniPHY controller

  • In the IP catalog, select:
Library
    Memory Interfaces and Controllers
        Memory Interfaces with UniPHY
            DDR3 SDRAM Controller with UniPHY
  • Select checkbox Enable Hard External Memory Interface
  • In tab PHY Settings configure:
    • Speed Grade: 8
    • Memory clock frequency: 375Mhz
    • PLL reference clock frequency: 62.5Mhz
    • Rate on Avalon-MM interface: Full
    • supply Voltage: 1.35V DDR3L
  • In tab Memory Parameters
    • In preset select: JEDEC DDR3-1G6 2GB X8 and apply
    • Memory device speed grade: 400Mhz
    • Total interface width: 24
    • Row address width: 14
  • In tab Controller Settings
    • checkbox: Generate power-of-2 data bus widths for Qsys or SOPC Builder
    • checkbox: Enable Configuration and Status Register Interface (Internacl JTAG)
    • checkbox: Enable Error Detection and Correction Logic
  • Click on finish
  • Connect following signals:
    • coreclkout -> pll_ref_clk
    • coreclkout -> mp_cmd_clk_0
    • coreclkout -> mp_rfifo_clk_0
    • coreclkout -> mp_wfifo_clk_0
    • coreclkout -> csr_clk
    • nreset_status -> global_reset
    • nreset_status -> soft_reset
    • nreset_status -> mp_cmd_reset_n_0
    • nreset_status -> mp_rfifo_reset_n_0
    • nreset_status -> mp_wfifo_reset_n_0
    • nreset_status -> csr_reset_n

Span extender

DDR3 memory is to large for PCIe BAR domain. Then we have to use a span extender to adapt PCIe BAR domain to DDR3 domain.

  • Select span expander in IP Library:
Library
    Basic Functions
        Bridges and Adaptors
            Memory Mapped
                Address Span Extender
  • Configure it with these options:
    • Datapath Width: 64bits
    • Slave Word Address Width: 20bits
    • Finish
  • Connect following extender signals:
    • coreclckout -> clock
    • nreset_status -> reset
    • Rxm_BAR1 -> windowed_slave
    • expanded_master -> avl_0
    • Rxm_BAR0 -> cntl
      • Change base address of cntl to 0x0000_4000

The resulting schematics should give the figure below.

The full connections between DDR and PCIe schematic

Adding the button and led (PIO)

  • In IP Library select:
Library
    Processors and Peripherals
        Peripherals
            PIO (Parallel I/O)
  • Configure it with these options:
    • Direction: Bidir
    • checkbox Synchronously capture
    • Edge Type: RISING
    • checkbox Generate IRQ
    • IRQ Type: EDGE
  • click on finish
  • export external_connection to pio
  • Connect following signals:
    • coreclkout -> clk
    • nreset_status -> reset
    • Rxm_BAR2 -> s1
    • irq -> Rxmirq
