Quartus / Modelsim Compile Order

**moserw** · July 21st, 2009, 07:51 AM

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).

Code:

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:

Code:

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.

Code:

# 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

# ** 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

try "add files" to project in Quartus menu, in the order you want

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!
