Synplify能通过,但是Quartus综合报错

Vincentvan

Error:Can't resolve mutiple constant drivers for net "Mon[5]" at ....(..)   
Error:Constant driver at ....(..)

第二个错误的对应代码是

代码：


always@(posedge IN2) if(reset) case(POS) 3'b000: Sec<=6'b0; 3'b001: Min<=Min+6'b1; 3'b010: Hour<=Hour+6'b1; 3'b011: Day<=Day+6'b1; 3'b100: Mon<=Mon+6'b1; default: second<=7'b0; endcase else ;





哪位大大说一下这两个错误是什么意思。不太明白。
