Analog Verilog, Verilog AMS...

Hi...

I am looking for a synthesizer and a simulator for verilog with analog / Verilog -AMS or something that would let me include analog parts in my design such as an op-amp / DAC / ADC etc.

I searched google for such a tool for hours and did not find anything.

I would prefer a free tool... but tell me about it anyway even if it is not a freeware.

I think you want mixed signal FPGA parts. Try looking here.
