[SV] Dynamic Array Characteristics

Dynamic array of features:

 

bit[7:0] d_array[];

d_array = new[4];

d_array ={0,1,2,3};

d_array = new[10];//原来的四个元素被清空

d_array = new[10](d_array);//原来的四个元素还存在

function void funcs();
      int pos[$] ;
    //   缩减操作 xor ， or ， and ，  xnor  ， sum ， product 等
    $display("the sum is %d ",array.sum());
    $display("the and is %d ",array.and());
    $display("the  or is %d ",array.or() );
    $display("the xor is %d ",array.xor());
    $display("the product is %d ",array.product());//乘积
