求各位大神帮忙解一下！
新人小白设计的一个用数码管实现的跑酷游戏，求大家帮个忙了！
这个感觉应该是跑马灯的游戏吧
用的是8个数码管，要同时控制数码管的不同部分，我后来又把不同部分给拆开来了，我觉得错误是一个数码管o_led[7:0]这样的不能把o_led[7:0]里的某个位，单独拿出来在其他的always里用
然后打算把不同模块拆开来放到子模块里来设计，这个还是不太懂..
我对此也不太了解 还是坐等高手吧
提示明显就是少了一个end， 在提示错误的always语句找下哪个begin丢了end
always @ (posedge i_clk_50M or negedge i_rst)
begin
begin
