VHDL Hardware Design

VHDL is a Hardware Description Language (HDL) for designing digital circuits, FPGAs (Field-Programmable Gate Arrays), and ASICs (Application-Specific Integrated Circuits). Instead of manually designing circuits with gates, you write VHDL code describing the circuit's behavior or structure. A synthesizer converts VHDL into gates that run on an FPGA or are fabricated as an ASIC. You write entities (interfaces), architectures (implementations), and testbenches (tests). You simulate designs to verify correctness, then synthesize to hardware.
