Yes, what i want to say is that when an EDA vendor comes to sell us tools
always offers tools that works with VHDL. I am not saying that those tools
not support Verilog. For example, with Xilinx ISE is available the XST
synthesizer, one version for VHDL and another for Verilog either with
Modelsim. The seminars that Insight,Avnet or Mentor do here are focused on
the VHDL design or simulation capabilities of those tools, only because is
the most popular in this area.

Yes, I agree. In the last design we have done one Core was written in
Verilog and the rest in VHDL.

Obviously industry is the most important client for EDA vendors, but must
be know that the progression into new tools, languages and methodologies
that finally EDA vendors sell to the industry have been developed into the
academia and scientific world. An in that world VHDL not seems to be dead.
