Re: [myhdl-list] Re: Feedback request on decorators in MyHDL

Jan,

We use Aldec Riviera with MyHDL. It works great.

Also, Riviera supports VHPI.

You can get an evaluation version of Riviera if that helps to get the 
VHDL support done.

One thought on VHDL support, we (and I'm sure there are others) would 
like to help write the toVHDL module. My problem is I don't know where 
to start or what really needs to be done. What could be used from 
toVerilog and so on.

Maybe we could figure out how to break the design up into some pieces 
that a few of us could tackle to get toVHDL done?

Unfortunately (my opinion) VHDL is very popular in FPGA designs and I 
would say 75% of our clients either prefer or require we deliver VHDL.
