用VHDL 语言描述度7段LED数码显示管，其开发均在FPGA中-using VHDL descr iption of 7 degrees LED digital display tubes, which were developed in FPGA

基于MAXPLUS II 的软件设计，这里面有几个小程序，用于VHDL的GDF设计，含有LED数码管的显示驱动程序，还有3选一，十选一程序。-II FPGA-based design software, there are several small procedures, GDF for VHDL design with a digital LED display driver of the procedures, there is a three elections. 10 election
