I suggest to add a new page (e.g [[vhdl_cosimulation]]) and make it
accessible under the "Development Zone".

It's progress, so it's always the right way! To implement VHDL
co-simulation, your efforts will be very helpful, so I suggest
to document your findings while they are still fresh.

However, as you can see from the toVHDL page, I am currently
suggesting to try to find a way to verify without co-simulation.
I am sceptical that we will get VHDL co-simulation to work
as needed any time soon; so for VHDL conversion it would be
helpful if we can do without it.

Thanks and regards,

Jan
