Because here in Europe, companies still use mostly VHDL. Verilog skils don't go very far. > Mostly bad VHDL design goes to FPGA, good Verilog design goes to ASICs. Uhm...

VHDL is huge, yes (actually the largest language i know), but at least it has a clean design, compared to Verilog which looks like someone tried to hammer C into a form that it can simulate hardware too. In number of pitfalls and ambiguities, i think Verilog is worse. Especialy if you consider that certain Verilog constructs differ only in one character, but have very sublte different meanings. A very good way for hard to trace down typos. > ghdl and freehdl are light years away from quality of icarus. Yet, i got ghdl running and simulating within minutes while it took me half a day to figure out why icarus wasn't. But yes, ghdl and freehdl are far a away from being feature complete, though i don't think that was the question here.
