- I posted the same question a couple of months ago and got some information.
- I am very interested in the same issue. I would appreciate if you would share
- me the information you would get too.
-
- So far, what I get to know are
-
- Commercial availability of the Verilog <-> VHDL translators
-
- Cadence VDOC-454 Verilog to VHDL translator
- Cadence is the originator of the Verilog-HDL and it seems
- like VDOC-454 has a quite good coverage on Verilog to VHDL
- translation. It costs $200k~300k.
- It translates User Defined Primitives and architectural
- description very good. Now, I am giving my benchmark example
- to see how good it translates behavioral Verilog description
- to VHDL. I will let you know when their benchmark comes out.
- I am not sure if they have VHDL to Verilog translator.
-
- InterHDL Verilog <-> VHDL translator
- A company called InterHDL has Verilog to VHDL and VHDL to
- Verilog translator. I don't have any further information
- about their products now.
-
- Synopsys
- If the Verilog or VHDL description is logic synthesizable
- (means written in Register Transfer Level), Synopsys can do
- the job too. It means it can only translate subset of the
- language.
-
-
- I didn't get any information about public domain Verilog <-> VHDL translator
- so far. I imagine there are no such things because there are very few
- people in this planet who has an access to both Verilog and VHDL based
- simulator at this moment.
-
- My own observation and comment about the issue is, language definition of
- the Verilog-HDL is closely related to implementation of the Verilog-XL
- simulator. And some of its' features are not essential to describe Hardware
- but essential to speed up simulation throughput. On the other hand, VHDL
- is more pure for describing Hardware. I think somebody needs to work out
- to accumurate those differences to make a good translator.
- I am not sure if this is very realistic but it would be very nice that
- somebody in the world defines subset of those language for portability of
- the HDL description.
