Fatal: out of memory - problems #1003

Hi Nick

I run into out-of-memory problems when running large pseudo-random simulations with VUnit. Could you have a look?

I see that you provide a -H option for setting the heap. However, I could not find out how to use this with VUnit. And in general ideally I wouldn't have to pass any special options for those test-cases. Neither GHDL nor Questa require a special handling. The simulations are a bit bigger but still not huge.

VUnit has a nvc.heap_size option to set that.
