本文簡單討論并總結了VHDL、Verilog,System verilog 這三中語言的各自特點和區別As the number of enhancements to variousHardware Description Languages (HDLs) hasincreased over the past year, so too has the complexityof determining which language is best fora particular design. Many designers and organizationsare contemplating whether they shouldswitch from one HDL to another.
