I am exploring the alternative option of using the GHDL simulator.

I looked at this briefly at the start of the project. However I was familiar with the Modelsim product so went for the simple option.

However this was just with the Core being simulated. Now that I have an array I am starting to feel the limitations as mentioned before. I theory GHDL should not have this limitations and so it might run faster !

The other thing is that I can run it on my Mac which means I won't have to log into my machine. However apparently the Linux version has some form of PLI so things may still be better done there.
