Tricky thanks for the support,

I notice also when we use constant for initialization the mfi file is correctly generated and it should be one solution but the modification of a package is for me not welcome in my case.

Another side note: any reason you're using VHDL '87 syntax for file IO rather than '93?

Because of read function in textio package: 


    procedure READ(L:inout LINE; VALUE: out bit; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out bit);
    procedure READ(L:inout LINE; VALUE: out bit_vector; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out bit_vector);
    procedure READ(L:inout LINE; VALUE: out BOOLEAN; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out character; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out character);
    procedure READ(L:inout LINE; VALUE: out integer; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out integer);
    procedure READ(L:inout LINE; VALUE: out real; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out real);
    procedure READ(L:inout LINE; VALUE: out string; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out string);
    procedure READ(L:inout LINE; VALUE: out time; GOOD : out BOOLEAN);
    procedure READ(L:inout LINE; VALUE: out time);
