    10、在过程赋值语句always语句块里赋值,称为过程赋值,always@ 后面的括号里是敏感列表,如下用持续赋值语句描述了一个异或门电路,与它等价的过程赋值语句是() input wire a,b; output wire c; assign c = a^b;

    A.input wire a,b; output reg c; always@(a,b) assign c = a^b;

    B.input wire a,b; output wire c; always@(a and b) assign c = a^b;

    C.input wire a,b; output reg c; always@ * assign c = a^b;

    D.input wire a,b; output logic c; always_comb assign c = a^b;
