Problem with queue

SystemVerilog

Hi All
I want to make two dimensional queue in the SV and I need to push and pop more than one element at the same time.
I don’t know how to do that, would you give me some suggestions?
Thanks

Here’s an example which pushes elements in 2D queue first then pops values back


int q[$][$] ;
int val ;

initial begin

 for ( int i = 0 ; i < 2 ; i ++ ) 
 begin
   for ( int j = 0 ; j < 2 ; j ++ ) 
    begin
      q[i].push_back(i+j*10); // Pushes elements in 2D queue . 
      $display("q[%0d] is %0p",i,q[i]);
    end
 end

 for ( int i = 0 ; i < 2 ; i ++ ) 
 begin
   for ( int j = 0 ; j < 2 ; j ++ ) 
    begin
      val = q[i].pop_back();
      $display("val is %0d",val);
    end
 end

 end 

 // Note that ::  q[i][j].push_back( .. ) would be Error as q[i][j] is leaf element ( packed element )  !!

How to pop more than one element at the same time?

In reply to peter:

At a time you can pop only 1 element . So if you want 2 elements you should call pop twice

In reply to peter:

Queues are most efficient for pushing/popping one element at a time from the front or back of the queue. You can also use array concatenation and the streaming operators for all kinds of array manipulation. It would help if you could explain more what you are looking to accomplish, especially where you want to put the multiple elements you want to pop off. It might be more useful to use dynamic arrays instead of queues.
