SystemVerilog -- 3.3 SystemVerilog for loop SystemVerilog for loop SystemVerilog中的循环多次重复一组给定的语句,直到不满足给定的表达式。与所有其他过程块一样,循环中需要多个语句被for和for begin end关键字括起来。 Syntax For循环使用三步方法控制其语句的执行: 初始化影响循环运行次数的变量 在执行循环之前,...
systemverilog module for_loop_example; integer arr[9:0]; initial begin for (int i = 0; i < 10; i = i + 1) begin arr[i] = 0; end // 打印数组内容以验证结果 for (int j = 0; j < 10; j = j + 1) begin $display("arr[%0d] = %0d", j, arr[j]); end end...
Note that is just a shorter version to the following loop : `foreach` `for` for(inti =0; i <$size(array); i++)begin// Statements inside the for loopend Example #2: Multidimensional Arrays module tb;intmd_array [5][2] ='{'{1,2},'{3,4}, '{5,6},'{7,8}, '{9,10}};...
Example #3 - Adding multiple modifiers In the code shown below,jis decremented after each iteration of theforloop along with incrementingi. moduletb;stringarray[5]='{"apple","orange","pear","blueberry","lemon"};initialbeginfor(inti=0,j=array[i].len()-1;i<$size(array);i++,j--)b...
for(initializing_expression;terminating_expression;loop_increment_expression) begin ... end 1. 2. 3. 4. 在Verilog中,用来控制for循环的变量必须在循环体之前声明。如果两个或多个并行程序中的循环使用相同的循环控制变量,那么就有可能出现一个循环修改其他循环还在使用的循环控制变量的情况。在for循环中,System...
SystemVerilog arrays are data structures that allow storage of many values in a single variable. A foreach loop is only used to iterate over such arrays and is the easiest and simplest way to do so. Syntax The foreach loop iterates through each index st
# For Loop Example A foor loop is a sequential statement used to execute a set of sequential statements repeatedly, with the loop parameter taking each of the values in the given Range from left to right. The example (in the design.vhd tab) shows the declaration of an _enumaration type_...
valArray— Create a column vector,index, from subsequent columns of arrayvalArrayon each iteration. For example, on the first iteration,index=valArray(:,1). The loop executes a maximum ofntimes, wherenis the number of columns ofvalArray, given bynumel(valArray(1,:)). The inputvalArraycan be...

In your example, just handle the "out" assignment from within the same generate loop: generate if (L>0) begin : L_non_zero reg pipe[W-1:0][L-1]; assign out[W-1:0] = pipe[L-1]; // Note your indexing of pipe is wrong too - see the other thr...
