Quartus / Modelsim Compile Order

Hi,

I am wondering if anybody can tell me how to set the compile order for modelsim.

I have created a small test project in VHDL where I directly instantiate an

entity (without component declaration VHDL-93).


entity comp_inst is
	port 
	(
		a	: in std_logic;
		y	: out std_logic
	);
end entity;
architecture rtl of comp_inst is
begin
	U1: entity work.my_not(rtl) port map (a, y);
end rtl;

When I start Modelsim from Quartus via the "EDA RTL Simulation" command,

Quartus is generating a .do script with the following compile order:


vcom -93 -work work {C:/altera/work/comp_inst/comp_inst.vhd}
vcom -93 -work work {C:/altera/work/comp_inst/my_not.vhd}

Modelsim is generating the following error message during compilation.


#  vcom -93 -work work {C:/altera/work/comp_inst/comp_inst.vhd}
#  Model Technology ModelSim ALTERA vcom 6.4a Compiler 2008.08 Oct 22 2008
#  -- Loading package standard
#  -- Loading package std_logic_1164

#  -- Compiling architecture rtl of comp_inst
#  ** Error: (vcom-11) Could not find work.my_not.
#  ** Error: C:/altera/work/comp_inst/comp_inst.vhd(14): (vcom-1195) Cannot find expanded name "work.my_not".
#  ** Error: C:/altera/work/comp_inst/comp_inst.vhd(14): Unknown expanded name.
#  ** Error: C:/altera/work/comp_inst/comp_inst.vhd(15): VHDL Compiler exiting

#      while executing
#  "vcom -93 -work work {C:/altera/work/comp_inst/comp_inst.vhd}"

If I swap the compile order of the two entities and restart the *.do script within

Modelsim everything is working fine.

Anyway on the next start Quartus has overwritten the modified *.do script.

Is there any way to force quartus to generate a script with the right compile order?

Thanks!

BTW I am using Quartus 9.0 Web Edition and Modelsim Altera Starter Edition 6.4a

    I changed the order in "Projekt - Add/Remove files in Projekt..." and also tried to change the order in "Project Navigator - Files" sheet but the order in the .do script does not change.

    Any other idea?

    It works if you change the order in the "Project Navigator - Files" sheet and afterwards start the "analysis & synthesis" process.

    Thanks for the help!

    Within modelsim menu use "compile" and select submenu "compile order..."

    Best Regards,

    Johi.
