10.3.4. Insufficient Memory in Your PC

If you are running the ModelSim* - Intel FPGA Edition simulator, the limitation on memory size may mean that you have insufficient memory to run your simulation. Or, if you are using a 32-bit operating system, your PC may have insufficient memory.

Typical simulation tool errors include: "Iteration limit reached" or "Error out of memory".

When using either the Intel® generic memory model, or a vendor specific model quite large memory depths can be required if you do not specify your simulation carefully.

For example, if you simulate an entire 4-GB DIMM interface, the hardware platform that performs that simulation requires at least this amount of memory just for the simulation contents storage.

Note: Refer to Memory Allocation and Max Memory Usage in the vendor's readme.txt files for more information.
