"Mentor Graphics will not allow an inexpensive license switch from our
present VHDL to the verilog"
Try asking if they can trade a verilog license for a vhdl license that
you can spare for the time being.

Hi,
I was able to make Xilinx Edition ModelSim(free) work both for
verilog and vhdl. Follow the below procedure.
What you can do is first install
vhdl version, then copy vhdl folder from
C:\Modeltech_xe_starter\xilinx\vhdl
to different location. Then uninstall the modelsim and again install
this time for verilog, this time you have
C:\Modeltech_xe_starter\xilinx\verilog
Now copy the vhdl from previous location to this location
C:\Modeltech_xe_starter\xilinx\
If you now open the modelsim you have both libraries.
Thanks
rao

Going from Verilog to VHDL isn't as big a headache as you think.
Go to http://www.confluent.org/wiki/doku.php and click on HDL comparison
to get a quick guide on the differences in Confluence, Verilog and VHDL.

OK, I found the documentation on NetGen. I'll give it a try. Thanks everyone for responding.

Kevin, I wouldn't mind simulating in VHDL, but the Xilinx tool won't let me setup any of the "create simulation model" processes to output VHDL. I only get a variety of verilog flavors to choose from. (My source files are verilog.) Do you know a different way?
You can get a VHDL netlist post-synthesis (depending upon the
synthesizer you are using), post-NGD build, post-map, or post-PAR.
Debugging your RTL from a post-NGD build VHDL netlist might not be as
easy as debugging a Verilog RTL sim, but it may be your best option and
requires no more cash. See the help for the Xilinx executable 'netgen'
for details on creating VHDL netlists from NGD or NCD files. -Kevin

We have a tight schedule so I will stick with the familiar language. I would use the VHDL simulator but Xilinx tools won't put out a VHDL model from verilog source files. Mentor Graphics will not allow an inexpensive license switch from our present VHDL to the verilog (They charge full price and give us no credit for the previous full price purchase). I can't use the "Xilinx Edition ModelSim" becuase it won't support my target, the XC2VP20, as far as I know.

Maybe you should ask them for Riviera instead of Active-HDL?

Last price list shows definitely more than 4,500 for Verilog-only
Active-HDL PE. I don't know if they will separate the simulator
from the development environment.
