门级建模中，以下调用语句正确的是（ ）。
A: or or1(out, in1 ,in2);
B: or or1(in1 ,in2，out);
C: buf b1(in, out1, out2);
D: buf b1(out1, in, out2);
A: or or1(out, in1 ,in2);
B: or or1(in1 ,in2，out);
C: buf b1(in, out1, out2);
D: buf b1(out1, in, out2);
举一反三
- 下面梯形图程序的功能是,当M2.0=1时,( ) A: IN1+IN2=OUT B: IN1-IN2=OUT C: IN1×IN2=OUT D: IN1÷IN2=OUT
- OUT是普通线圈指令，步数是（） A: 1~5 B: 1~2 C: 1~4 D: 1~6
- out内置对象 A: 1 B: 2 C: 3 D: 4
- Who does not even have to get out of his car? Sometimes (1) _______ (2) ________ does not even have to get out of his car.
- 以下语言是数据流建模方式吗？ A: xor x1(a,b,c): B: assign adder_out = mult_out + out; C: always @ (a or b or sel) begin if (sel) c = a; else c = b;?end D: and a1(out,in1,in2);
