    file_name = "data.bin";
    file = $fopenr(file_name);

The order of the arguments to $fread shohld be reversed.

I also saw a warning that Questasim didn't know what $fopenr was so I switched to $fopen("path","r") as shown in LRM.

I switched the inputs and get the same error, now on elaboration stage vs a runtime error.

file = $fopen(file_name,"r");
i = $fread(memΎ], file);

I finally got this to work:
$readmemb("path", mem);

That read in the contents of the file and loaded, line by line, into the array I defined.

thx
