Hi all! I am experiencing a very strange and rather frustrating problem while trying to run the same backannotated simulation in two different versions of modelsim. In both cases I am using exactly the very same files for everything, and also the same compilation and simulation commands. The old version (modelsim 5.8b) simulates fine and (...)

It looks like you need to include the library where your fifo is compiled. Or, you failed to compile the fifo.
So, if what I said above is correct, you need to use library statements and use statements to bring in the unbound object.
If the internal_memory: fifo is compiled in a library other than "work", you will need to add

Yesterday I generate modelsim license using ef@licgen.
It can't works.
I changed pc's date backward and regenerate license.
Then change pc's date now.
modelsim works well.
I tested another pc. Same problem.
Anyone have the same problem ?

modelsim is so primitive it is hard to beleive why it is so popular. (microsoft ?)
what mentor does today is just to take this old software and criple it to se, pe, xe , starter, xilinx , altera versions.
the only thing they do is put loop delays inside.
every new version they come up with force you to compile all your files and packages.

modelsim eventually supported nested class declarations in versions after 10.1
But the example code you show here will never compile because there is a missing endclass. Even with nested classes, there needs to be a matching endclass for each class declaration. The error message is misleading because the intent was never to have an nested c

Early versions of modelsim do not support untyped mailboxes.
My recommendation is to always use typed mailboxes anyways - it is safer.
// parameter type T = bit;
mailbox #(packet) mbx;
function new(mailbox#(packet) mbx);
this.mbx = mbx;//(100);
task run(int count);
repeat (count) begin
pkt = new();

The xilinx Spartan III board is in fact made by Digilent, but is subsidised by Xilinx.
From the Digilent website their $89 board is loaded with a 50K gate device, as opposed to the 200k device on the $99 'Xilinx' board.
Evaluation versions of ISE 6.2i and modelsim 5.7g (xilinx edition) are also supplied with the $99 kit.

you dont need to compile textio, its already included in modelsim.
the standard_textio_additions is a VHDL 1993 version of the VHDL 2008 additions. A newer version of modelsim will support this by default (so you dont need to include it).
