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

• Right click on qsys_tfht.qsys and set as top level
• 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

Adding the DDR3

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

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

Qsys component schematic

The resulting schematics should give the figure below.
