SystemVerilog object creation process

Question

class parent;
int a = 10;
endclass

class child extends parent;
int b = 10;
endclass

module main;
  parent P;
  child C;

  P = new();
  C = new();

  initial begin
    $display("a=%d\n",C.a);
  end
endmodule

I tried to run this code using Synopsys VCS. It is giving an error at the object creation after the handle declaration. The error is as follows:

Error-[SE] Syntax error Following verilog source has syntax error : "class.sv", 20: token is '=' P = new();

The output does not match the code you show. What are you expecting? — dave_59

Your edits completely changed the sense of the question so that the answer is no longer an answer to the question and will make no sense to future readers. So, I have rolled them back. If you have another question, please ask it as another question. I have also deleted all the extraneous output from VCS. — Matthew

Hi Matthew! All I am expecting is to create a object using the the class handle. If you run the above code it gives error but if you do parent P = new() Then it does not give any error. I want to know the reason behind this. — K. Piyush

Hi @K.Piyush, then ask a new question and I will answer it. The idea behind Stack Overflow is that your questions and answers become useful to future Googlers. Conversations like this and edits that completely change the sense of a question are not useful to future Googlers. — Matthew

Put your constructors inside the initial block.
