Error in modelsim when manipulating with floating point controller

Guys this s the error i get while manuplatin with floating point controller

** Error: (vcom-11) Could not find work.fpu_test.
# ** Error: floating_point_unit_test.vhd(9): Cannot find expanded name: work.fpu_test.
# ** Error: floating_point_unit_test.vhd(9): Unknown record element "fpu_test".
# ** Error: floating_point_unit_test.vhd(11): VHDL Compiler exiting
# ** Error: C:/Modeltech_6.0/win32/vcom failed.

what could be the vissible error .. does this error mean that my fpu_test library s missing..


with regards,

** error: (vcom-11) could not find work.test.

Arun,
It is likely that you have a package named fpu_test that's not yet compiled when you are compiling floating_point_unit_test.vhd file. Can you show us initial 10 lines of file floating_point_unit_test.vhd? Is there a use clause as:

use work.fpu_test.all;

or some thing?

If so, analyse the file that contains fpu_test pkg first. Note that VHDL compilation is order-dependent.

modelsim vcom-11

arun it not fpu_test library s missing.. it means that u first compile the unit => fpu_test in the work directory, then do compile other files that has dependecy with fpu_test, u error will be gone

error: (vcom-11) could not find work

Am still getting this error.. as u told i agree to the fact that VHDL is order executive so i did the execution n order i still get the same error

Error: (vcom-11) Could not find pid.fpu_test.
** Error: C:/Modeltech_6.0/examples/pid/floating_point_unit_test.vhd(9): Cannot find expanded name: work.fpu_test.
** Error: C:/Modeltech_6.0/examples/pid/floating_point_unit_test.vhd(9): Unknown record element "fpu_test".
** Error: C:/Modeltech_6.0/examples/pid/floating_point_unit_test.vhd(11): VHDL Compiler exiting


and the first few lines of my test bench is

LIBRARY ieee;
USE ieee.std_logic_1164.ALL;
USE ieee.std_logic_unsigned.ALL;

LIBRARY std;
USE std.textio.ALL;

LIBRARY work;
USE work.fpu_test.ALL;

ENTITY floating_point_unit_test IS
END floating_point_unit_test;

ARCHITECTURE arch OF floating_point_unit_test IS

COMPONENT floating_point_unit
PORT(

here USE work.fpu_test.all is given clearly. but i get the error mentioned above

modelsim use expanded name

check if package fpu_test is in library work.

If so, you can try:

library ieee, std, work;
use ieee....
use ....
....

cannot find expanded name modelsim

Arun,
Can you show your compile commands for fpu_test file and floating_point_unit_test file? i.e. if you try the following, it should work:

vcom -work work fpu_test.vhdl
vcom -work floating_point_unit_test.vhd
