WebDynamic Array in SystemVerilog - VLSI Verify Dynamic Array in SystemVerilog As name dynamic suggests, an array whose size can be changed during run time simulation. The size of an array can be specified during run-time by using new [ ]. Note: By default, the size of a dynamic array is 0 unless a new [ ] is used. Dynamic array declaration WebThese arrays can have variable size as new members can be added to the array at any time. Consider the example below where we declare a dynamic array as indicated by the empty square brackets [] of type rand. A constraint is defined to limit the size of the dynamic array to be somewhere in between 5 and 8.
