One other possibility: you can invoke C code from GHDL (if using the GCC form
of GHDL) which can do whatever you want and pass information in. For example,
I've used that to provide initial memory content: VHDL memory loaded from data
read from a file by C code. I've also used it to interface C models of I/O
devices to I/O channels modeled as VHDL code. That gives a lot of power and is
one of the reasons I use GHDL.
