A clock buffer is used to duplicate the 50 MHz oscillator, so each bank of FPGA I/O bank 3/4/7/8
has two clock inputs. The three programming oscillators are low-jitter oscillators which are used to
provide special and high quality clock signals for high-speed transceivers. Figure 2-10 shows the
control circuits of programmable oscillators. The clock generator controller in the MAX II CPLD
can be used to program the CDCM61001 and CDCM61004 to generate 1G Ethernet SFP+ and
SATA reference clocks respectively. The Si570 programmable clock generator is programmed via
an I2C serial interface to generate the 10G Ethernet SFP+ reference clock. Two SMA connectors
provide external clock input and clock output respectively.

DDDDRR33 SSOO--DDIIMMMM
The development board supports two independent banks of DDR3 SDRAM SO-DIMM. Each
DDR3 SODIMM socket is wired to support a maximum capacity of 8GB with a 64-bit data bus.
Using differential DQS signaling for the DDR3 SDRAM interfaces, it is capable of running at up to
800MHz memory clock for a maximum theoretical bandwidth up to 102.4Gbps. Figure 2-13 shows
the connections between the DDR3 SDRAM SO-DIMMs and Stratix V GX FPGA.

QQDDRRIIII++ SSRRAAMM
The development board supports four independent QDRII+ SRAM memory devices for very-high
speed and low-latency memory access. Each of QDRII+ has a x18 interface, providing addressing
to a device of up to a 8MB (not including parity bits). The QDRII+ has separate read and write data
ports with DDR signaling at up to 550 MHz.
Table 2-14, 1Table 2-15 and Table 2-16 lists the QDRII+ SRAM Bank A, B, C and D pin
assignments, signal names relative to the Stratix I GX device, in respectively.

The FPGA development board is designed to fit entirely into a PC motherboard with x8 or x16 PCI
Express slot. Utilizing built-in transceivers on a Stratix V GX device, it is able to provide a fully
integrated PCI Express-compliant solution for multi-lane (x1, x4, and x8) applications. With the
PCI Express hard IP block incorporated in the Stratix V GX device, it will allow users to implement
simple and fast protocol, as well as saving logic resources for logic application. Figure 2-15
presents the pin connection established between the Stratix V GX and PCI Express.
The PCI Express interface supports complete PCI Express Gen1 at 2.5Gbps/lane, Gen2 at
5.0Gbps/lane, and Gen3 at 8.0Gbps/lane protocol stack solution compliant to PCI Express base
specification 3.0 that includes PHY-MAC, Data Link, and transaction layer circuitry embedded in
PCI Express hard IP blocks.
Please note that it is a requirement that you connect the PCIe external power connector to 6-pin 12V
DC power connector in the FPGA to avoid FPGA damage due to insufficient power. The
PCIE_REFCLK_p signal is a differential input that is driven from the PC motherboard on this
board through the PCIe edge connector. A DIP switch (SW7) is connected to the PCI Express to
allow different configurations to enable a x1, x4, or x8 PCIe.
Table 2-22 summarizes the PCI Express pin assignments of the signal names relative to the Stratix
V GX FPGA.

just one of many different applications an FPGA can be used in storage appliances. The Stratix V
GX device can bridge different protocols such as bridging simple bus I/Os like PCI Express (PCIe)
to SATA or network interfaces such as Gigabit Ethernet (GbE) to SATA. The SATA interface
supports SATA 3.0 standard with connection speed of 6 Gbps based on Stratix V GX device with
integrated transceivers compliant to SATA electrical standards.
The four Serial ATA (SATA) ports include two available ports for device and two available ports for
host capable of implementing SATA solution with a design that consists of both host and target
(device side) functions. 1Figure 2-16 depicts the host and device design examples.

IInnttrroodduuccttiioonn
The System Builder is a Windows based software utility, designed to assist users to create a Quartus
II project for the FPGA board within minutes. The generated Quartus II project files include:
Quartus II Project File (.qpf)
Quartus II Setting File (.qsf)
Top-Level Design File (.v)
External PLL Controller (.v)
Synopsis Design Constraints file (.sdc)
Pin Assignment Document (.htm)
The System Builder not only can generate the files above, but can also provide error-checking rules
to handle situation that are prone to errors. The common mistakes that users encounter are the
following:
Board damaged for wrong pin/bank voltage assignment.
Board malfunction caused by wrong device connections or missing pin counts for connected
ends.
Performance dropped because of improper pin assignments

This section will introduce the general design flow to build a project for the FPGA board via the
System Builder. The general design flow is illustrated in the 1Figure 3-1.
Users should launch System Builder and create a new project according to their design requirements.
When users complete the settings, the System Builder will generate two major files which include
top-level design file (.v) and the Quartus II setting file (.qsf).
The top-level design file contains top-level Verilog wrapper for users to add their own design/logic.
The Quartus II setting file contains information such as FPGA device type, top-level pin assignment,
and I/O standard for each user-defined I/O pin.
Finally, Quartus II programmer must be used to download SOF file to the FPGA board using JTAG
interface.

on the FPGA as shown in 1Figure 3-4. Each component of the FPGA board is listed where users can
enable or disable a component according to their design by simply marking a check or removing the
check in the field provided. If the component is enabled, the System Builder will automatically
generate the associated pin assignments including the pin name, pin location, pin direction, and I/O
standards.
Note: The pin assignments for some components (e.g. DDR3 and SFP+) require associated
controller codes in the Quartus project otherwise Quartus will result in compilation errors.
Therefore, do not select them if they are not necessary in your design. To use the DDR3 controller,
please refer to the DDR3 SDRAM demonstration in Chapter 6.
Figure 3-4 System Configuration Group
Programmable Oscillator
There are two external oscillators on-board that provide reference clocks for the following signals
SFP_REFCLK, SFP1G_REFCLK, SATA_HOST_REFCLK and SATA_DEVICE_REFCLK. To use
these oscillators, users can select the desired frequency on the Programmable Oscillator group, as
shown in Figure 3-5. SPF+ or SATA should be checked before users can start to specify the desired
frequency in the programmable oscillators.
As the Quartus project is created, System Builder automatically generates the associated controller
according to users’ desired frequency in Verilog which facilitates users’ implementation as no
additional control code is required to configure the programmable oscillator.

This section describes how to program Si570- and CDCM61004. For detail programming
information, please refer to their datasheets which are available on the FPGA System CD.
Si570
The Si570 utilizes Silicon Laboratories advanced DSPLL® circuitry to provide a low-jitter clock at
any frequency. The Si570 are user-programmable to any output frequency from 10 to 945 MHz and
select frequencies to 1400 MHz with < 1ppb resolution. The device is programmed via an I2C serial
interface. The differential clock output of the Si570 directly connects to dedicated reference clock
input of the Stratix V GX transceiver for SFP+ channels. Many applications can be implemented
using this function. For example, the 10G Ethernet application can be designed onto this board by
feeding a necessary clock frequency of 644.53125MHz or 322.265625MHz from the Si570.
Figure 5-1 shows the block diagram of Si570 device. Users can modify the value of the three
registers RFREQ, HS_DIV, and N1 to generate the desired output frequency.

The output frequency is calculated using the following equation:
When Si570 is powered on, the default output frequency is 100 MHz. Users can program the output
frequency through the I2C interface using the following procedure.
6. Freeze the DCO (bit 4 of Register 137).
7. Write the new frequency configuration (RFREQ,HSDIV, and N1) to Register 7–12.
8. Unfreeze the DCO and assert the NewFreq bit (bit 6 of Register 135).
The I2C address of Si570 is zero and it supports fast mode operation whose transfer rate is up to

In this section we will demonstrate how to use the Terasic Si570 Controller implemented in Verilog
to control the Si570 programmable oscillator on the FPGA board. This controller IP can configure
the Si570 to output a clock with a specific frequency via I2C interface. For demonstration, the
output clock is used to implement a counter where the MSB is used to drive an LED, so the user can
get the result from the frequency of the LED blinking. We will also introduce the port declarations
and associated parameter settings of this IP. Figure 5-2 shows the block diagram of this
demonstration.

Block Diagrams of Si570 Controller IP
The block diagram of the Si570 controller is shown on Figure 5-3. Shown here are four blocks
named i2c_reg_controller, i2c_bus_controller, clock_divider and initial_config in Si570 controller
IP. Firstly, the i2c_reg_controller will generate an associated Si570 register value for the
i2c_bus_controller based on user-desired frequency. Once i2c_bus_controller receives this data, it
will transfer these settings to Si570 via serial clock and data bus using I2C protocol. The registers in
Si570 will be configured and output the user-desired frequency.
Secondly, the clock_divider block will divide system clock (50 MHz) into 97.6 KHz which is used
as I2C interface clock of i2c_bus_controller. Finally, the initial_config block will generate a control
signal to drive i2c_reg_controller which allows the Si570 controller to configure Si570 based on
default settings.

To use the Si570 Controller, the first thing users need to determine is the desired output frequency
in advance. The Si570 controller provides six optional clock frequencies. These options can be set
through an input port named “iFREG_MODE” in Si570 controller. The specified settings with
corresponding frequencies are listed in Table 5-4. For example, setting “iFREG_MODE” as 3’b110
will configure Si570 to output 655.53 MHz clock.

When the output clock frequency is decided, the next thing users need to do is to enable the
controller to configure Si570. Before sending enable signal to Si570 controller, users need to
monitor an output port named “oController_Ready”. This port indicates if Si570 controller is ready
to be configured or not. If it is ready, logic high will be outputted and the user needs to send a high
level logic to “iStart” port to enable the Si570 Controller as shown in Figure 5-4. During Si570
configuring, the logic level of “oController_Ready” is low; when it rises to high again that means
the user can configure another frequency value.

Users can get a desired frequency output from si570 by modifying these three parameters :
new_hs_div ,new_n1 and fdco.
Detailed calculation method is in following equation:
fdco = output frequency * new_hs_div * new_n1 * 64
There are three constraints for the equation:
1. 4850 < output fequency * new_hs_div * new_n1 < 5600
2. 4 <= new_hs_div <= 11
3. 1 <= new_n1 < =128
For example, you want to get a 133.5 mhz clock, then
fdco = 133.5 x 4 x 10 x 64 = 341760d = 0x53700
Find a mode in this RTL code section and modify these three parameters,as shown below:
new_hs_div = 3'b100 ;
new_n1 = 4'b1010 ;
fdco = 23'h05_3700 ;
In addition, Silicon Lab also provide the corresponding calculation tool.
Users can refer to the Programmable Oscillator tool (See Figure 5-5) mentioned in below link to
calculate the values of new_hs_div and new_n1, then, the fdco value can be calcuted with above
ftdo equation.

QDR II/QDR II+ SRAM devices enable you to maximize memory bandwidth with separate read
and write ports. The memory architecture features separate read and write ports operating twice per
clock cycle to deliver a total of four data transfers per cycle. The resulting performance increase is
particularly valuable in bandwidth-intensive and low-latency applications.
This demonstration utilizes four QDRII+ SRAMs on the FPGA board. It describes how to use
Altera’s “QDRII and QDRII+ SRAM Controller with UniPHY” IP to implement a memory test
function. In the design, the four QDRII controllers share the PLL/DLL/OCT due to limited DLL

PCI Express Basic I/O Transaction
Under read operation, the Terasic PCIe IP issues a read signal followed by the address of the data.
Once the address is received, a 32-bit data will be sent along with a read valid signal. Under write
operation, the PCIe IP issues a write signal accompany with the address to be written. A 32-bit data
is written to the corresponding address with a data enable signal of write operation. All the write

To support greater bandwidth and to improve latency, Terasic PCIe IP provides a high speed DMA
channel with two modes of interfaces including memory mapping and FIFO link. The
oFIFO_MEM_SEL signal determines the DMA channel used, memory mapping or FIFO link,
which is enabled with the assertion of a low and high signal, respectively. The address bus of DMA

PCI Express Interrupt
Altera PCI Express IP supports both interrupt types specified in PCI Express protocol. One of them
is Legacy interrupt and the other one is MSI interrupt. This reference design shows how to
use Legacy interrupt mechanism to handle interrupt. Table 7-3 lists the associated port names along
with the description. The Edge Detector captures the timing when the button is pressed and
generates a pulse on iINT_STS. The PCIe Hard IP sends an INTA_Assert message upstream to the
Root Complex in response to a low-to-high transition. It also sends an INTA_Deassert message in
response to a high-to-low transition. A pulse on oINT_ACK to user logic indicates that an
INTA_Assert or INTA_ Deassert message has been sent.

The FPGA System CD contains a PC Windows based SDK to allow users to develop their 32-bits
software application on Windows 7/Window XP 32/64-bits. The SDK is located in the “CDROM
\demonstrations\PCIe_SW_KIT” folder which includes:
PCI Express Driver
PCI Express Library
PCI Express Examples
The kernel mode driver requires users to modify the PCIe vender ID (VID) and device ID (DID) in
the driver INF file to match the design in the FPGA where Windows searches for the associated
driver.
The PCI Express Library is implemented as a single DLL called TERASIC_PCIE.DLL

(TERASIC_PCIEx64.DLL for 64-bits Windows). With the DLL exported to the software API, users
can easily communicate with the FPGA. The library provides the following functions:
Device Scanning on PCIe Bus
Basic Data Read and Write
Data Read and Write by DMA
For high performance data transmission, DMA is required as the read and write operations are
specified under the hardware design on the FPGA.
PCI Express Software Stack
Figure 7-8 shows the software stack for the PCI Express application software on 32-bits Windows.
The PCI Express driver is incorporated in the DLL library called TERASIC_PCIE.dll. Users can
develop their application based on this DLL. In 64-bits Windows, TERASIC_PCIE.dll is replaced
by TERASIC_PCIEx64.dll, and wdapi921.dll is replaced by wdapi1100.dll.
