Configuring the Cyclone 10 FPGA on the CycloFlex is the process of
programming the compiled/synthesized user project into the FPGA. Once the
FPGA is configured with the user project, the CycloFlex board is usable with
the code. There are two methods to configure the Cyclone 10 FPGA

• Direct JTAG access
• On Board Configuration Flash chip

JTAG Access to the Cyclone 10

Direct JTAG access allows the Quartus Prime Lite software to program the
object file directly into the FPGA using JTAG. This will configure the FPGA
with the user project using volatile memory. If the power is removed from the
Cyclone 10, the chip will lose its configuration.

Configuration Flash Programming

The Cyclone 10 FPGA requires configuration before it can be used to perform
the functions of the user code. The CycloFlex board includes a 4Mbit Configuration
Flash chip that is designed to store the user code. Then, when the power is cycled
(On/Off), the FPGA will read the contents of the Configuration Flash and set up the
functionality of the user code within the chip. The user will program a *.pof file
into the flash chip using Quartus.

Earth People Technology has created demonstration software that provides a
bi-directional communication pathway that can transfer data at 500Kbytes/second.
All source code is provided and the user is encouraged to use this software to as
a base to create custom projects for their need.

The CycloFlex contains three Seven Segment LED Displays. These displays are
controlled by I/O pins from the FPGA. The user manual explains how to write user
to display characters on the Displays

The CycloFlex has a Serial Flash chip on the bottom right board. This allows
the user to create a powerful Soft Core Processor within the FPGA. Processor
code can be loaded into the Flash Chip via the USB to SPI Serial link. The
user can then execute code out of the Flash Chip. The 50MHz oscillator on board
makes this a powerful project for the intermediate FPGA user. The CycloFlex Board
is the perfect board for powerful projects.

ModelSim/Questa is included Free with the Quartus Prime Package. ModelSim/Questa is a
powerful tool for finding errors in the user code before you go to synthesis.
Earth People Technology has created a guide that walks the user through
creating a project and verifying functionality of user code. This guide will
explain the use of the TestBench, Tasks, and Models in verification of the user
code. In specifics, the guide will explain:

• Create a ModelSim/Questa Project
• Create a Makefile and Compilation of user code
• Create a TestBench and Stimulus of user code
• Add Synopsys Design Constraints,
• Assign Inputs and Outputs to pins of the Cyclone 10
• Create Models for user code to Interact With
• Add Clock Signals, Resets, and Timing Elements
• Debug the Functionality of user code
