Overview
Introduction
This tutorial introduces you to using SOPC builder with the Excalibur
devices. It shows you how to use SOPC builder and the Quartus® II
software to create and process your own Excalibur device system module
design that interfaces with components provided on the EPXA1
development board.
This tutorial is for SOPC builder novices or users who are new to using
embedded systems in FPGAs. The tutorial guides you through the steps
necessary to create, build the software and simulate an Excalibur
hardware design system module, called xa_tutorial, and download it onto
the EPXA1 development board. This simple, single-master system
module has an Excalibur device processor and associated advanced
microprocessor bus architecture (AMBA) high-performance bus (AHB)
system peripherals and interconnections.
After you create the xa_tutorial design and connect to external pins, you
can download it to the Altera® Excalibur device on the EPXA1
development board. The external physical pins on the Excalibur device
are in turn connected to other hardware components on the EPXA1
development board, allowing the ARM-based Excalibur Stripe to interface
with SDRAM, flash memory, LEDs, switches, and buttons.
This tutorial is divided into the following three sections:
Altera Corporation
■
“Design Entry” on page 11 teaches you how to create the Excalibur
device system module in a block design file (.bdf) using the
MegaWizard® Plug-In Manager and SOPC Builder.
■

Compilation
The compiler compiles the xa_tutorial design entity, and any subordinate
design entities, using the xa_tutorial compiler settings. As the design
compiles, the Status window automatically displays, as a percentage, the
total compilation progress and the time spent in each stage of the
compilation. The results of the compilation are updated in the
Compilation Report window. The total compilation time may be 10
minutes or more, depending on your system.
The compiler may generate one or more of the following warning
messages that do not affect the outcome of your design (see Figure 26).

Software Build &
Programming
You have already completed creating and instantiating the xa_tutorial
system. This chapter guides you through the steps in SOPC Builder for
building the software code and running the design on the EPXA1
development board.
This section gives instructions for building the software code using either
the excalibur-build utility in the SDK Shell using GNU Tools or using
Quartus II Software Builder with GNU tools.
To create the software build, you will add the software files, select
software build settings, and establish the linking of the files. In this section
you will set up the Quartus II software to compile the program. The
various compiler and linker options will be set to produce a .hex file.

Software Build & Programming
You can simulate the design using the simulation files that SOPC Builder
automatically generates. To run a simulation with the Excalibur stripe
simulation model (ESS), perform the following steps:
For more information on ESS, refer to the Excalibur Stripe Simulation User
Guide.
1.
In the Quartus II software, choose SOPC Builder (Tools menu).
2.
Select the System Generation page.
3.
Click Run ModelSim to launch your simulation project in
ModelSim. ModelSim opens and gives you a list of options to load,
compile, and run your simulation.
4.
To compile and load your simulation files, type ‘’s’’
5.
To bring up a waveform window, type ‘’w’’
6.
To launch the simulation, type run - allr
ESS launches a telnet window to emulate the output of the stripe UART
and displays the following text from the printf:
‘’Look for a message on the LCD’’
You can view the signals in the ModelSim waveform window as the
simulation shows code being executed.
To program flash memory on the EPXA1 development board with the
flash image that you created in “Software Build” on page 45, perform the
following steps:
1
Ensure that you have set up the board as described in the EPXA1
Development Board Getting Started Guide.
1.
Choose Programs > Altera > GNU Tools and Excal Component >
XA SOPC SDK Shell (Windows Start menu).
2.
If you used the Quartus II Software Builder to generate the flash
image, change to the following directory:
<install directory>\tutorials\xa_tutorial

At the command prompt, type:
exc_flash_programmer.exe -g xa_tutorial_flash.hexr
After programming completes, the message Flash programmed
successfully appears in the command prompt window
(see Figure 27). The EPXA1F484C1 device resets and boots from the data
programmed into the flash memory. The LEDs on the development board
illuminate a pattern and the following message is output through the
UART:
Look for a message on the LCD.....
A message then displays on the LCD module (see Figure 27).
