>
This article explains how to compile a sample program, led, which is included in sythesijer_samples on [[DE0-Nano/Synthesijer]]. This shows how to write the build image, and execute it on DE0-Nano.~
~
This article basically uses the same sample program as the article of [[DE0-Nano/Synthesijer_QuickStart]], and the sample program makes an LDE on DE0-Nano blink.~
~
In the led directory there is the make file. Then, build the file with make command.~
~
 $ cd ~/synthesijer_samples/sample/led/
 $ make
 java -cp /home/beat/synthesijer-20140818.jar synthesijer.Main led.java counter.java
 Output VHDL: counter.vhd
 Output VHDL: led.vhd
 Output Verilog HDL: counter.v
 Output Verilog HDL: led.v
 javac -cp /home/beat/synthesijer-20140818.jar:. led_top.java
 java -cp /home/beat/synthesijer-20140818.jar:. led_top
~
Create a project file on DE0-Nano System Builder. To be consist with the name of Synthesijer's sample, the name of the project file is led.~
~
Move the created project file to Ubuntu. Change the name of led_top.v to something else.~
On Ubuntu, edit led_top.qsf for matching led_top.vhd. led_top.vhd is a part of led, which has been built.~
~
As exstick.ucf is defined, the pin-allocation is not specified for reset. Also, led is built, there are led_top.vhd, led.vhd, and counter.vhd are created. Copy these three files and placed them in the same directory.~
~
 $ vi exstick.ucf
 
 NET reset      LOC = A12  | IOSTANDARD = LVCMOS33;    # "USER_RESET"
 NET reset      TIG;
 
 NET clk        LOC = N7 | IOSTANDARD = LVCMOS33;               # "USER_CLOCK"
 
 NET clk TNM_NET = clk;
 TIMESPEC ts_clk = PERIOD clk 25000 kHz;
 
 NET q LOC = A2 | IOSTANDARD = LVCMOS33;
~
 $ vi led_top.vhd
 library IEEE;
 use IEEE.std_logic_1164.all;
 use IEEE.numeric_std.all;
 entity led_top is
   port (
      clk : in std_logic;
      reset : in std_logic;
      q : out std_logic
    );
 end led_top;

Then, the rest of steps is identical to what describes in [[DE0-Nano/Synthesijer_QuickStart]].~
~
Start up Quartus, and select Top.qpf from Open Project in the File, which is located at the menu bar.~
 $ quartus
~
- Error message 1~
Click Start Complication in Processing at the menu bar.~
Start compiling the files, which are created in the project file.~
~
''Caution'': A lot of Warning will appear. But, there are no issues here. Please ignore it.~

>
Click Pin Planner in Assignments section. Then, make sure that all changes (editing the file and relocating files)  shown above are effective.~
~
- Error message 2~
Click Programmer in Tools section at the menu bar. Programmer works as writing (programming) a created image to DE0-Nano. Programmer also selects a device for being written. In this article, USB-Blaster is selected.~
~
If the screen indicates No Hardware, click Hardware Setting and select USB-Blaster, which can be found in “Currently selected hardware.” Please look at the screen shot below for the reference.~
~
''Caution'': If the choice of USB-Blaster is not be displayed, please check the rule file of udev.~

>
As all process has been completed. Click Start, which is located in Programmer. Then, the created image is transferred to DE0-Nano.~
As progress reaches at 100% (successful), LED0 on DE0-Nano starts blinking.~
