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);

1、下面的代码综合后，存在几个触发器？（B）module reg_test(clk,in1,out1);input clk;input in1;output out1;reg reg1,reg2,reg3,out1;always@(posedge clk)beginreg1 = in1;reg2 = reg1;reg3 = reg2;out1 = reg3;endendmodule A: 4 B: 3 C: 0 D: 1

指令是用于将IN输入端的源数据传送（复制）给OUT1输出的目的地址，并且转换为OUT1指定的数据类型，源数据保持不变

1 . To "blank out" is probably______.

Producer(){While(1){ ; ;Buffer(in)=m;In=(in+1)%n; ; ;}}consumer(){While(1){ ; ;m= Buffer(out);out=(out+1)%n; ; ;}

你想提醒别人要小心，应该说： A: Come in! B: Go out1 C: Be careful!

下面哪种代码执行后是与其他结果不一样的？ A: module mux2_1(a,b,sel,out); input a,b,sel; output out; assign out=(sel==1)?a:b; endmodule B: module mux2_1(a,b,sel,out); input a,b,sel; output out; reg out; always@(a or b or sel) begin case(sel) 0: out=a; 1: out=b; endcase end endmodule C: module mux2_1(a,b,sel,out); input a,b,sel; output out; reg out; always@(*) if(sel==0) out=a; else out=b; endmodule

在下面代码中ｘ为何值时输出结果为“out2”？ switch(ｘ){ case 1:System.out.println("out1");break; case 2: case 3:System.out.println("out2");break; default:System.out.println("end"); }
