I'm trying to construct a SOPC component of JOP
[1].
As it did not work in the FPGA on the first try
(of course) I would like to simulate it with ModelSim
(Altera version).

However, when I start ModelSim from Quartus I get following
error:

# ** Error: (vcom-11) Could not find
C:\altera\Modeltech_ae\win32aloem/../altera/vhdl/altera.altera_europa_support_lib.
# ** Error: D:/usr/cpu/jop/quartus/tmp/jop_system.vhd(24): (vcom-1195) Cannot find
expanded name:
'altera.altera_europa_support_lib'.
# ** Error: D:/usr/cpu/jop/quartus/tmp/jop_system.vhd(24): Unknown record element
"altera_europa_support_lib".


I found the VHDL file in the Quartus directory. Do I need to
compile it (once ?) with ModelSim, or is there a PATH issue?

Versions: Quartus 6.0sp1, ModelSim ALTERA 6.1d

Thanks,
Martin

Compile it.

... when working with UNIX, you may want to use a
specified script,
forcing the compiler to put everything required into the "work"
directory as destination with one "click".
