What are the types of New & Virtual in SV ?

[carrot]

Hi All,

I heard a couple of questions on system verilog very recently......

1. What are the types of new ? ( the hint given was, there are 4 types of new )
Is there really 4 types of new in system verilog?

2. What are the different types of Virtual ?

I'am really unaware of these 4 types of new and types of Virtulal.
Anyone aware of it, Can you please share it?

Thanks,
Carrot

Re: New & Virtual in SV !

Is this an interview trivia question?

Did you mean what is the use of the new and virtual keywords in SystemVerilog?

new is used to construct a class or covergroup, as well as allocate a dynamic array. Not sure what the 4th usage is.

virtual is used as a modifier to a method declaration, an abstract class declaration, and to declare a variable that can hold a handle to an interface.
