如何使用指针或引用进行综合？

typedef struct packed {
  logic          in_use;
  logic          fully_received;
} t_packet_info;

t_packet_info packets[A-1:0][B-1:0];

t_packet_info packet_ptr;

assign packet_ptr = packets[ a ][ b ];

always_ff @(posedge clk) begin
  packet_ptr <= //any value
end

I want to use packet_ptr to be able to allocate it in an always_ff as if I wrote packets[ a ][ b ].

可能吗？我想避免使用宏。
