Default EDK + Modelsim simulation : Memory allocation failure

Dear

When I simulate one EDK project (with multi-processors), Modelsim
reports an error "Memory allocation failure".

I tested the EDK project with 6 microblazes and it was okay.

Now I am trying to simulate the EDK project with 12 Microblaze.

What I did was
1. Implement the system using EDK.

In Modelsim,
2. compile "system.vhd" and "system_init.vhd"
3. compile "testbench"
4. Load "testbench" (configuration with BRAM initialization) with SDF
file.

In step 4, following error occurred:

----------------------------------------------------------------------------
# ** Error: system.vhd(681006): (vopt-4) ****** Memory allocation
failure. *****
# Please check your system for available memory and swap space.
# ** Error: system.vhd(681006): (vopt-4) ****** Memory allocation
failure. *****
# Please check your system for available memory and swap space.

voptk.exe - application error
The exception unknown software exception (0xc00000fd) occurred in the
application at location 0x77c3011e
-----------------------------------------------------------------------------

My windows machine has 4GB RAM. I think 4GB is more than enough.

Does anyone have this experience?
