ModelSim 'work' library error on using ise

[jsg1227]

Hi,
I'm trying to simulate on ModelSim PE Student Edition 6.6d
from Xilinx ISE 10.1.03.

When I run the simulation in ISE,
ModelSim starts but stops very soon showing the following message :

# vsim -do \{do \{test_tb.fdo\}\}
# ** Error: (vsim-19) Failed to access library 'work' at "work".
# No such file or directory. (errno = ENOENT)
# Error loading design

I think ISE doesn't create 'work' library for some reason.
I have the same error for a very simple Verilog code and TB.
FYI, modelsim.ini file and license are normal,
and I reinstalled first ModelSim and then ISE to see if it's some kinda data defect.

Do you think it is because it's on student edition and uncorrectable?

Someone please help me~

Thanks in advance:smile:

You can just learn how to use the modelsim to create the project.

You need to add the work Library. then "Compile HDL simulation Libraries".

 

[TrickyDicky]

try the command "vlib work"

Thank you all for helping this problem.

Actually I aim for a design with some scale, maybe ~10,000 slices, and some IP cores will be utilized.
So I am a little reluctant to directly build it in ModelSim, which has limit on the design due to the version.
(Before this error, I could simulate a large design on the ModelSim even though it was student version.)

But maybe I have to try direct ModelSim simulation if there's no way that works.

I tried "vlib work" and got another error message :

# vsim -do \{do \{test_tb.fdo\}\}
# ** Error: (vsim-3170) Could not find 'C:\...\TEST2\work.{test_tb.fdo}}'.
# Error loading design

I tested copying test_tb.fdo into the newly generated 'work' directory by the command but still had the same message(3170).


Thank you again for concerning about this.
