The syntax error is caused by the empty parentheses in the definition of interface Int(). To fix this error, you should remove the empty parentheses from the interface definition. The corrected code should be:

interface Int;
class t1;
integer a[string]; //REQ-EXT-10007
function new;
a = '{"a":40, "b":60, "c":80}';
endfunction
endclass
class t2;
integer b[string]; //REQ-EXT-10007
function new;
b = '{"aa":44, "bb":66,"cc":88}';
endfunction
endclass
t1 inst1 = new; //REQ-EXT-10501
t2 inst2 = new; //REQ-EXT-10501
endinterface

After making this change, the code should compile without any syntax errors.

Sure, I'd be happy to help you with that! Here are some examples of how to modify the class constructor body according to REQ-EXT-10007:

Example 1: Modifying the class constructor body for t1

In this example, we modify the class constructor body for t1 to initialize the integer array "a" with default values of 0.

class t1;
  integer a[string];  //REQ-EXT-10007

  function new();
    foreach (a[key]) a[key] = 0; // initialize with default value of 0
  endfunction
endclass

Example 2: Modifying the class constructor body for t2

In this example, we modify the class constructor body for t2 to initialize the integer array "b" with a specific set of values.

class t2;
  integer b[string];  //REQ-EXT-10007

  function new();
    b = '{ "aa": 44, "bb": 66, "cc": 88 }'; // initialize with specific values
  endfunction
endclass

Example 3: Modifying the class constructor body for both t1 and t2

In this example, we modify the class constructor body for both t1 and t2 to initialize their respective integer arrays with default values of 0.

class t1;
  integer a[string];  //REQ-EXT-10007

  function new();
    foreach (a[key]) a[key] = 0; // initialize with default value of 0
  endfunction
endclass

class t2;
  integer b[string];  //REQ-EXT-10007

  function new();
    foreach (b[key]) b[key] = 0; // initialize with default value of 0
  endfunction
endclass

I hope these examples help you understand how to modify the class constructor body according to REQ-EXT-10007. Let me know if you have any other questions!

The syntax error is caused by the use of reserved keyword "array" as a variable name. To fix this error, you can rename the variable "array" to something else, such as "my_array". Here's an updated version of the code:

interface Int();
  class t1;
    integer a[string];  //REQ-EXT-10007
    function new;  //class constructor body need be modified according to REQ-EXT-10007
      a = '{"a":40, "b":60, "c":80}';
    endfunction
  endclass
  class t2;
    integer b[string];  //REQ-EXT-10007
    function new;  //class constructor body need be modified according to REQ-EXT-10007
      b = '{"aa":44, "bb":66,"cc":88}';
    endfunction
  endclass
  t1 inst1 = new; //REQ-EXT-10501
  t2 inst2 = new;  //REQ-EXT-10501
endinterface

module top;
  Int in();
  virtual Int testint = in;
  associative my_array[string]; // Renamed variable "array" to "my_array"
  initial begin
    #1;
    my_array = testint.inst1.a;
    $display("testint.inst1.a = %p", testint.inst1.a); //CHECK-001:'{"a":40, "b":60, "c":80}
    $display("my_array = %p", my_array); //CHECK-002:'{"a":40, "b":60, "c":80}
    #2;
    my_array = testint.inst2.b;
    $display("testint.inst2.b = %p", testint.inst2.b); //CHECK-003:'{"aa":44, "bb":66,"cc":88}
    $display("my_array = %p", my_array); //CHECK-004:'{"aa":44, "bb":66,"cc":88}
  end
endmodule
