Ok. I´ve only used MAX+PLUS for a short time (about 8 months) and I haven´t
learned VHDL yet, so the circuits I've made have been build by using all kinds
of "virtual components" (mega/macrofunctions) as building blocks in the
MAX+PLUS graphic editor. It also uses IEEE Std VHDL, Alteras AHDL and Verilog
