Hi.
I am trying to read a file from my verilog-AMS program (.csv, it is a lookup table with 2 lists of arrays).

real code[41:0];
real thresh[41:0];


initial begin
     openfile = $fopen("file", "rb");
     readfile = $fscanf("file", "%g %g\n",code[40:0],thresh[40:0]);
end

ncvlog: *E,NOPSOM file,33|72): Part-select or indexed part-select cannot be applied to memory [4.2.2(IEEE)].
     readfile = $fscanf("file", "%g %g\n",code[40:0],thresh[40:0]);
                                                                                         |
ncvlog: *E,NOPSOM (file,33|85): Part-select or indexed part-select cannot be applied to memory [4.2.2(IEEE)].
     module testlib.adcdiscrete:verilogams


The $fopen part of the codes is OK. The syntax/s of the $fscanf function is the same as the one in the manual.

I have no idea what's going on

It is still not working
To try to solve the problem/s I created a program which just open, write and read a .txt file.



module readfile ( );

integer file;
integer readfile;
integer code;
integer a;

initial begin
     
     a=999;
     
     file = $fopen("/home/sunny/Desktop/loadfile/testing.txt", "rw");
     $strobe("\nfile OK? = %d\n", file);

       $fwrite(file, "%g", a);

     readfile = $fscanf(file, "%d\n", code);
     $strobe("readfile OK?=%d", readfile);
     $strobe("code = %d\n", code);      

end


I can open and write to the file (it shows '999' in the .txt), but I cannot read from the file, in fact, the variable readfile returned as "-1" and the code returned as "x".

Thank you very much for your help, guys!!
