Modelsim Altera and Quartus II Web Edition Error

Hi,

Struggling here with something obviously environmental.

I had been using Quartus II Web Edition for about 2 months and now need to hook it up to Modelsim Altera. So I downloaded it.

I tried the small design example here: http://www.altera.com/support/examples/modelsim/exm-timing-verilog-msaltera.html

I am consistently getting this message once I launch Modelsim Altera through the "Run EDA RTL Simulation" Option in Quartus II. ModelSim Altera launches but consistently reports the following error:

#

# vcom -work work C:/Documents

# Model Technology ModelSim ALTERA vcom 6.1g Compiler 2006.08 Aug 12 2006

# ** Error: (vcom-7) Failed to open design unit file "C:/Documents" in read mode.

# No such file or directory. (errno = ENOENT)

# ** Error: C:/altera/61/modelsim_ae/win32aloem/vcom failed.

# Error in macro ./multiplier_run_msim_rtl_verilog.do line 8

# C:/altera/61/modelsim_ae/win32aloem/vcom failed.

# while executing

# "vcom -work work C:/Documents"

Why is it defaulting to C:/Documents?

Thanks much.

    Are you using files at "C:\Documents and Settings\%USERNAME%\My Documents"? Quartus does not allow spaces in the pathname for SOPC Builder and perhaps other things. It might be that ModelSim or something in the NativeLink communication between Quartus and ModelSim does not allow spaces in pathnames.

    Yup, Quartus doesn't follow spaces in path names.

    Thanks for verifying!

    Hi

    I am also getting the same error with ModelSim SE 6.4. when I am trying to run from .do file its giving the following error.

    # ** Error: (vcom-7) Failed to open design unit file "F:/code/aes/pack.vhd" in read mode.

    # No such file or directory. (errno = ENOENT)

    # ** Error: C:/modeltech_6.4/win32/vcom failed.

    But I am able to compile the same file by direct loading. Whatever do file I use was working fine for ModelSim 5.4E.

    Any suggestions will be appreciable.

    Thanks In Advance
