verilog实现一位全加器，使用枚举（不同卡诺图化简）列出每种情况的a，b，cin，编译报错
module fadd ( input a, input b, input cin, output reg sum, output reg cout );
always@(a or b or cin)
case({a,b,cin})
000: sum=0，cout=0;
001: sum=1，cout=0;
010: sum=1，cout=0;
011: sum=0，cout=1;
100: sum=1，cout=0;
101: sum=0，cout=1;
110: sum=0，cout=1;
111: sum=1，cout=1;
endcase
endmodule

问题可能是出在 000: sum=0，cout=0; 这些语句。
建议改成 000: begin sum=0; cout=0; end 。
其他分支类似。
或者你也可以把 sum，cout，拆分成两个always块，这样代码更简洁。
