Software Requirements

To develop your own designs for the T20 device on the board, you must install the Efinity
software. You can obtain the software from the Efinix® Support Center under Efinity
Software (www.efinixinc.com/support/).

The Efinity® software includes tools to program the device on the board. Refer to the
Efinity® Software User Guide for information about how to program the device.

Learn more: Efinity® documentation is installed with the software (see Help > Documentation) and is also
available in the Support Center under Documentation (www.efinixinc.com/support/).

Installing Standoffs

Before using the board, attach the 4 standoffs to the board with the screws provided in the
kit.

Warning: The board can be damaged if you over tighten the screws. Tighten all screws to a torque between
4 ± 0.5 kgf/cm and 5 ± 0.5 kgf/cm.

Overview

The board features the Efinix® T20 programmable device in a 256-ball FBGA package, which
is fabricated using Efinix® Quantum™ technology. The Quantum™-accelerated programmable
logic and routing fabric is wrapped with an I/O interface in a small footprint package. T20
devices also include embedded memory blocks and multiplier blocks (or DSP blocks). You
create designs for the T20 device in the Efinity® software, and then download the resulting
configuration bitstream to the board using the USB connection.

Note: For more information on T20 FPGAs, refer to the T20 Data Sheet, which you can download in our
Support Center under Docs (www.efinixinc.com/support/).

The FTDI FT2232H module has two channels to support SPI (FTDI interface 0) and
JTAG (FTDI interface 1) configuration. It receives the T20 configuration bitstream from a
USB host and writes to the on-board SPI NOR flash memory. After a reset in SPI passive
mode, the FTDI controller can also write the configuration bitstream directly to the
FPGA. Additionally, it supports direct JTAG programming mode in which it writes the
configuration bitstream directly to the FPGA through the JTAG interface.

Note: Refer to AN 006 Configuring Trion FPGAs for more information.
