ICCD 2009, Lake Tahoe, CA, USA. Presentation Slide
Example for FPGA/SFL beginners.
  1. FPGA Startup with SFL
  2. Make your own PC from scratch.
  3. Make your own game platform (Midway) from scratch.
Design flow with sfl2vl:
sfl2vl without license file can convert up to 500 lines of SFL. You can request for non profit license by sending blank mail to naohiko.shimizu+sfl2vl.nplic@gmail.com. Cut the license data (date and 16 hex-decimal digit) and past it in sfl2vl.dat. The license file should be placed in C:\Windows for windows, or /usr/local/bin for Linux, or /usr/bin for MacOSX. If you need full version, you can contact IP ARCH, Inc. for paid license.

You can install as
tar xzf sfl2vlbin-i386-linux-20100304.tar.gz -C /

    It is a simple stopwatch output to a VGA color display. You can control the stopwatch with the tree buttomns of the starter kit.
    Bit file for Spartan-3 Starter Kit is here.
    Enjoy, Naohiko. 
    This archive is a demonstration of sfl2vl usage.

You need following tools to test:
  1. HDL convertersfl2vl (see http://www.ip-arch.jp/indexe.html ).
  2. Z80 C Compiler SDCC (see http://sdcc.sourceforge.net/ )
  3. Xilinx ISE 6.1 web-pack or later
  4. Cygwin and Development tools (see http://www.cygwin.com )
If you want to simulate the release, you will required to have Verilog compiler.
  5. Icarus Verilog (see http://www.icarus.com/eda/verilog/ )

The design is developped for Spartan-3 starter kit, and the UCF file was
written to use the board.
If you need to export for other boards, write your own ucf, etc.

After you installed all the above tools, you should have proper
execute path environment variable to run these tools under cygwin.
Then you can simply type:

 make ise

This command will setup a subdirectory for ISE.
Start ISE navigator and open project under the 'stopwatch' directory.

Next step will generate download bit file for your board.

 make new.bit

You can download using IMPACT the new bit file in which 
BRAM was modified with the embedded program.

    EDA Linux LiveCD

    EDA Linux LiveCD is a bootable ISO9660 CDROM image. You can burn following image on a CDROM and boot your PC. EDA Linux LiveCD features: sfl2vl, sfl2vh, Icarus Verilog, Alliance VHDL tool set, Verilator and many tutorials.
    Usage 
    login_name: root
password: toor
To start X11, you can use 'go' script as:
# go 1280 
go script handles horizontal resolution of 800,1024,1280.
If you want other resolutions, use 'gui' command directry.

For PentiumM machines, EDA Linux may require BIOS patch.
It depends on your machine. You may able to use 855warp or 855patch.

    LiveCygwin packages:

    You need non profit license to make some packages. The package has a non profit license file with limited period. You can request for non profit license by sending blank mail to naohiko.shimizu+sfl2vl.nplic@gmail.com Cut the license data (date and 16 hex-decimal digit) and replace it of sfl2vl.dat in the extracted directory.
