如果条件为false,则循环将在此处结束。do while 因此,两者之间的区别在于,循环至少执行一次语句集。do while Syntax while(<condition>)begin// Multiple statementsenddobegin// Multiple statementsendwhile(<condition>); Example #1 - while loop moduletb;initialbeginintcnt =0;while(cnt <5)begin$display("cn...
$display"Start of do-while loop" do begin $display"Count: %0d" 1 end while5 $display"End of do-while loop" end endmodule 在这个例子中,循环体内的语句输出count的值,并且count在每次迭代后增加。do-while循环会在count小于5的条件下一直执行。 请注意,在SystemVerilog中,do-while循环是一个用于循环...
first value of r_Data[0] to allow the first iteration of the while loop to execute. If the first check of the while loop is not true, then the loop will never run. A do-while loop avoids the requirement that the first check is true, but this is only supported with SystemVerilog....

说来惭愧,写了很久的代码,我都不知道循环还有这种操作! 单层循环跳出for (int i1 = 0; i1 < 10; i1++) { System.out.println("i1 "+i1); if (i1>5) break; } 多层循环跳出再多层循环跳出之前,说个冷知识。 java的循环是 ... 循环嵌套 ...

This would be a systemverilog .sv program.2. My reference design has several BFM provisions I can just drive the one I want.3. For the MUT instantiation, I found it under the generated tb file : `ep_g3x8_avmm256_integrated_tb/ep_g3x8_avmm256_integrated...
