CompuPro CPU-68000 / VHDL vs TTL

---------------------------------------- Hi The problem is that things like VHDL and Verilog are really just maps of the silicon territory. They are not a complete definition. When pushing silicon to the speed limits with engineered circuits, there are times when the circuit just doesn't map everything into a descriptive language. Most people think that the ASIC flow is the primary method of creating new processors. That is only true if your not interested in creating the ulimate processor. As mentioned, this flow is great for a large number of embedded processors. The speed needed for these is typically at the lower end of things. I work for a company that creates processors, although we use a high level language to describe the architecture, we create many cicuits that could not be created by an automatic process. We use standard cells when performance isn't needed but many man years goes into optimizing the key circuits.
