Verilog is quite allright as a back-end format :-)

VHDL output - no plans, for the following reasons:

1. I would need an open-source VHDL simulator *with PLI support*
An Icarus for VHDL, let's say (thanks, Stephen Williams!). To verify
output conversion, it is essential to have co-simulation. As far
as I know, this is just not there for VHDL.

2. The fact that Verilog co-simulation and conversion works, 
demonstrates that "it can be done". There *is* now a path to
implementation using an intermediate :-) format that any
EDA tool will understand. For me personally and for 
the myhdl technology it makes more sense to tackle other areas 
(especially verification) than "to do it again". That having
said, I welcome any effort and any help from others to
fill in missing functionality, such as VHDL support.

Of course, I'll take back all of these points if sponsors show up.

Regards, Jan

    Python is fun, and now you can design hardware with it:
