Verilog and VHDL mix

Feb 13, 2004 4 Replies

I wonder if it is possible to synthesize on one chip VHDL and Verilog IP cores. I suppose the VHDL to Verilog or vice versa translator could be used. Ideas are welcome.

Can't you do that with Synplify? If not, you can always synthesize blocks of, say, VHDL, separately and then instantiate them as EDIF black boxes in the Verilog design.

You can usually do mixed language if you are prepared to pay lots of money for licenses. But if your doing Xilinx, or maybe something else, then have a look at the second method outlined here

. You can synthesis with XST in both Verilog and VHDL. I can't confirm if you can do both at once in one project I would need to check that. If I was doing on a design that is big enough to warrant 2 languages I would usually break it down into some kind of increment / modular flow anyway.

You can also use ISE toolset to write out a module in another language. It is there mainly for simulation but you can use it otherwise.

Current versions of Xilinx XST, Altera Quartus, and Synplify Pro all support mixed verilog/VHDL designs.

You can use both at once in the current version of XST.
