共阳型数码管字形码（二进制和十六进制）
1. 共阳型数码管，数码管显示0-f对应的段选输出信号(二进制)
1 parameter NUM0 = 8'b1100_0000, 2 NUM1 = 8'b1111_1001, 3 NUM2 = 8'b1010_0100, 4 NUM3 = 8'b1011_0000, 5 NUM4 = 8'b1001_1001, 6 NUM5 = 8'b1001_0010, 7 NUM6 = 8'b1000_0010, 8 NUM7 = 8'b1111_1000, 9 NUM8 = 8'b1000_0000, 10 NUM9 = 8'b1001_0000, 11 NUMA = 8'b1000_1000, 12 NUMB = 8'b1000_0011, 13 NUMC = 8'b1100_0110, 14 NUMD = 8'b1010_0001, 15 NUME = 8'b1000_0110, 16 NUMF = 8'b1000_1110;
2. 共阳型数码管，数码管显示0-f对应的段选输出信号（十六进制）
1 parameter NUM0 = 8'hc0, 2 NUM1 = 8'hf9, 3 NUM2 = 8'ha4, 4 NUM3 = 8'hb0, 5 NUM4 = 8'h99, 6 NUM5 = 8'h92, 7 NUM6 = 8'h82, 8 NUM7 = 8'hf8, 9 NUM8 = 8'h80, 10 NUM9 = 8'h90, 11 NUMA = 8'h88, 12 NUMB = 8'h83, 13 NUMC = 8'hc6, 14 NUMD = 8'ha1, 15 NUME = 8'h86, 16 NUMF = 8'h8e;
