最近写了一个八位共阴极数码管驱动的Verilog的代码,由于是初学所以有很多问题,下面这个是参数定义问题,两天了都没有解决,希望懂的朋友可以帮忙解答一下:
module nixie_tube(clk,wei,duan,dataport);//50MHZ时钟输入,wei:数码管位吗,duan:数码管段码,‘0’led亮
input clk;
output duan,wei;
output [7:0]dataport;
reg [7:0]dataport;
reg duan,wei;
integer count;///分频计数器,每计数到50000下clk_1k时钟翻转,T=20ns*50k=1ms
reg clk_1k;//数码管扫描时钟2ms
reg [2:0]wei_count;//位码计数器
parameter duan0 = 8'h3f,
wei0 = 8'fe,??出错处第30行
duan1 = 8'h06,
//wei1=8'fd,
duan2 = 8'h5b,
//wei2=8'fb,
duan3 = 8'h4f,
//wei3=8'f7,
duan4 = 8'h66,
//wei4=8'ef,
duan5 = 8'h6d,
//wei5=8'df,
duan6 = 8'h7d,
//wei6=8'bf,
duan7 = 8'h07,
//wei7=8'7f,
duan8 = 8'h7f,
duan9 = 8'h6f,
duanA = 8'h77,
duanB = 8'h7c,
duanC = 8'h39,
duanD = 8'h5e,
duanE = 8'h79,
duanF = 8'h71;
always @(posedge clk)//

Error (10112): Ignored design unit "nixie_tube" at nixie_tube.v(18) due to previous errors
请问为什么parameter wei0 = 8'fe;定义出错?

wei0 = 8'fe,看看这两个哪不一样?
