The constraint usesforeachloop to iterate over all the elements and assign the value of each element to that of its index. classABC;randbit[3:0]array[5];// This constraint will iterate through each of the 5 elements// in an array and set each element to the value of its// particular...

第三种方法使用SystemVerilog自带的随机函数来生成递增/递减数组,这时就可以不用使用constraint来实现,并且直接在program/module中的initial block中实现。 program rnd_arr_3;rand int arr3[];int arr_size;initial begin arr_size=$urandrange(6,12);arr3=new(arr_size);foreach(arr3[i])begin arr3[i]=$u...

Constraint Random Generation Coverage Driven Verification Assertion Based Verification. These features improve dramatically the verification process. SystemVerilog is an integrated part of the Simulation tool like Modelsim. There is no need for any external tool, GUI or interface (such as ...
