package a_pkg;
typedef struct packed{
logic [7:0] a;
logic b;
} t_a_field;
endpackage

module a #(parameter A=2) (
input a_pkg::t_a_field [A-1:0] userdata //
);

using autoinst in other module:
a
#(
.A(2)
)
u_a
(
/AUTOINST/
);

Result:
AUTOINST of a will result of an error
.a_pkg::t_a_field(a_pkg::t_a_field/.[A-1:0]/),

Current workaround
Use a non packed array
module a #(parameter A=2) (
input a_pkg::t_a_field userdata [A-1:0]//
);
