I've been trying to turn leds on and off with my XC9572XL demo board for few days with no success.
However when I made a new project with the supplied verilog demo file it works. (it must be me!)
Since I can only speak vhdl, i downloaded verilog to vhdl converter program http://www002.upp.so-net.ne.jp/morioka/v2v.html but it gives me syntax error on line 1 and line 28.
Please help?
