final procedure block does not work in ModelSim

Altera_Forum · ‎09-07-2015

SystemVerilog LRM (1800-2012):

--- Quote Start ---

A final procedure executes when simulation ends due to an explicit or implicit call to $finish.

--- Quote End ---

But the final block does not execute in ModelSim Altera Starter Edition 10.1e:cry:

I used the following code:


module test();
initial begin
   # 1 $display("Simulation has been started");
   # 1 $finish;
    end
final
    $display("This should be shown at the end");
endmodule

and this is the output:

# Simulation has been started# ** Note: $finish : C:/.../final_bug.sv(4)# Time: 2 ns Iteration: 0 Instance: /test

Are you running this code interactively? If so, $finish may be behaving like $stop.

By "interactively" you mean by using the ModelSim GUI, right?

By the way did you ever simulate a SystemVerilog code containing a "final block" with ModelSim? if not could you please try it and tell me the results?

thanks

Thank You Dave!

I guess instead of using the GUI, you typed the tcl script and this time the output looks fine.
