Hello World VHDL
A Blinking LED:
entity LEDtest is
port (
clk: in bit;
LED1: out bit;
LED2: out bit
);
end LEDtest;
architecture BEHAVIOUR of LEDtest is
signal count: integer range 0 to 16777215;
signal tmp:bit:='0';
begin
IN_process: process (clk)
begin
if clk'event and clk = '1' then
count<=count+1;
if count=16777215 then
count<=0;
tmp<=not tmp;
LED1<=tmp;
LED2<=not tmp;
end if;
end if;
end process;
end BEHAVIOUR;
With the following constraints file:
# Crystal Clock - use 32MHz onboard oscillator NET "clk" LOC = "P89" | IOSTANDARD = LVCMOS25 | PERIOD = 31.25ns ; # Wing1 Column A NET "LED1" LOC = "P91"; NET "LED2" LOC = "P92";
Use xc3prog to send to FPGA:
#just once (erased on reboot): sudo ./xc3sprog -c papilio ~/VHDL/LEDTest/LEDtest.bit -v #or use FTDI & FLASH to make non-volatile: sudo ./xc3sprog -c papilio -I../bscan_spi/bscan_spi_xc3s500e_papilio.bit ~/VHDL/LEDTest/LEDtest.bit -v -R
Or, via my raspberry pi:
f=LEDtest.bit ; scp $f pi:/tmp; ssh pi "sudo /home/joostje/debian/papilio/Papilio-Loader/xc3sprog/trunk/build/xc3sprog -c papilio /tmp/$f -v" # f=LEDtest.bit ; scp $f pi:/tmp; ssh pi "sudo /home/joostje/debian/papilio/Papilio-Loader/xc3sprog/trunk/build/xc3sprog -c papilio -I../bscan_spi/bscan_spi_xc3s500e_papilio.bit /tmp/$f -v -R"
Compiling xc3prog
(This is the GadgetFactory fork of Xc3sprog, for the official version, see Xc3sprog) Tested on Ubuntu 13.04 (beta) and raspberry Pi (raspbian)
sudo aptitude install libftdi-dev libusb-1.0-0-dev cmake git clone git://github.com/GadgetFactory/Papilio-Loader.git cd Papilio-Loader/xc3sprog/trunk mkdir build cd build cmake .. make sudo ./xc3sprog -c papilio ~/VHDL/AWGprovo/mem2.bit -v

Errors when programming using low-powerd devices
When using my Raspberry Pi to program papilio, these errors appear when the papilio board needs to give too much power to other devices, for instance the DX TM1638 Display:
$ xc3sprog -c papilio /tmp/$f -v design_top.bit 100% 277KB 277.2KB/s 00:00 XC3SPROG (c) 2004-2011 xc3sprog project $Rev: 691 $ OS: Linux Free software: If you contribute nothing, expect nothing! Feedback on success/failure/enhancement requests: http://sourceforge.net/mail/?group_id=170565 Check Sourceforge for updates: http://sourceforge.net/projects/xc3sprog/develop Using built-in device list Using built-in cable list Cable papilio type ftdi VID 0x0403 PID 0x6010 dbus data 00 enable 0b cbus data 00 data 00 Could not open FTDI device (using libftdi): device not found Unable to access FTDI device with either libftdi or FTD2XX
Apparently the FTDI232 disconnects when the power goes too low.
