2. Getting Started

The remaining chapters in this user guide lead you through the following

Cyclone V GX FPGA development board setup steps:

Inspecting the contents of the kit

Installing the design and kit software

Setting up, powering up, and verifying correct operation of the FPGA development board

Configuring the Cyclone V GX FPGA

Running the Board Test System designs

fFor complete information about the FPGA development board, refer to the

Cyclone V GX FPGA Development Board Reference Manual.

Before You Begin

Before using the kit or installing the software, check the kit contents and inspect the boards to verify that you received all of the items listed in “Kit Features” on page 1–1. If any of the items are missing, contact Altera before you proceed.

Inspect the Boards

To inspect each board, perform these steps:

1.Place the board on an anti-static surface and inspect it to ensure that it has not been damaged during shipment.

c Without proper anti-static handling, you can damage the board.

2.Verify that all components on the boards appear in place and intact.

1In typical applications with the Cyclone V GX FPGA development board, a heat sink is not necessary. However, under extreme conditions or for engineering sample silicon, the board might require additional cooling to stay within operating temperature guidelines. The board has two holes near the FPGA that accommodate many different heat sinks, including the Dynatron V31G. You can perform power consumption and thermal modeling to determine whether your application requires additional cooling. For information about measuring board and FPGA power in real time, refer to “The Power Monitor” on page 6–10.

fFor more information about power consumption and thermal modeling, refer to AN 358: Thermal Management for FPGAs.

4. Development Board Setup

The instructions in this chapter explain how to set up the Cyclone V GX FPGA development board.

Setting Up the Board

To prepare and apply power to the board, perform these steps:

1.The FPGA development board ships with its board switches preconfigured to support the design examples in the kit. If you suspect your board might not be currently configured with the default settings, follow the instructions in “Factory Default Switch Settings” on page 4–2 to return the board to its factory settings before proceeding.

2.The FPGA development board ships with design examples stored in the flash memory device. Verify the DIP switch (SW3.3) is set to the factory off (1) position to load the design stored in the factory portion of flash memory.

1The FPGA development board can be powered by the PCIe host adapter or the laptop power adapter. If you want to power the board by the PCIe host system, plug the FPGA development card into a standard PCIe connector. Alternatively, to power the FPGA development board using the laptop power adaptor, perform the following two steps:

3.Connect the 65 W, 15 VDC @ 4.3 A power supply to the DC Power Jack (J9) on the FPGA board and plug the cord into a power outlet.

c Use only the supplied power supply. Power regulation circuitry on the board can be damaged by power supplies with greater voltage, and a lower-rated power supply may not be able to provide enough power for the board.

4.Set the POWER switch (SW1) to the on position. When power is supplied to the board, blue LED (D23) illuminates indicating that the board has power.

The MAX V device on the board contains (among other things) a parallel flash loader (PFL) megafunction. When the board powers up, the PFL reads a design from flash memory and configures the FPGA. The DIP switch (SW3.3) controls which design to load. When the switch is in the factory off (1) position, the PFL loads the design from the factory portion of flash memory.

1The kit includes a MAX V design which contains the MAX V PFL megafunction. The design resides in the <install dir>\kits\cycloneVGX_5cgxfc7df31_fpga\examples\max5 directory.

When configuration is complete, the Config Done LED (D15) illuminates, signaling that the Cyclone V GX device configured successfully.
