动态转换(运行时进行待转换数值的检查)(不可综合) $cast系统函数: $cast( dest_var, source_exp ); //强制转换source_exp的结果为dest_var的类型 1. 用$cast转换失败时,源变量不变。$cast可返回状态标志,标识是否转换成功。 $cast的主要用途:将表达式的结果赋给enum类型变量。 1.9. 常数 Verilog常数类型: ...
push_back()方法将给定元素插入队列的末尾。 size()方法返回队列中的元素数。如果队列为空,则返回0。 Example - Queues module queue_data(); // Queue is declated with $ in array size integer queue[$] = { 0, 1, 2, 3, 4 }; integer i; initial begin $display ("Initial value of queue")...
我们将数独网格表示为9x9整数数组,在名为sudoku_solver_base的类中定义所有属性字段和约束。 class sudoku_solver_base; rand int grid[9][9]; // ... endclass 我们的第一个约束是数组中的所有元素都必须是 1 到 9 之间的数字,这很容易: constraint all_elements_1_to_9_c { foreach (grid[i, j]...

function int size ( ):返回队列中成员的数目。如果队列空,返回0; function void insert (int index, queue_type item):在指定的索引位置插入指定的成员; Q.insert(i, e)等效于Q= {Q[0:i-1], e, Q[i, $]}; function void delete (int index):删除指定索引位置的成员; ...

The result of this function is undefined if the argument doesn't have a self-determined size. The $sizeof function is deprecated in favour of $bits, which is the same thing, but included in the SystemVerilog definition. $simtime The $simtime system function returns as a 64bit value the...
