The top-down design methodology is primarily based on
automatic (computer-aided) synthesis of the gate-level
netlist, using a behavioral or structural
HDL description. The synthesized logic
is subsequently mapped onto a standard-cell library
or an FPGA (Field Programmable Gate Array). The top-down
design methodology is well suited for purely digital
designs with relatively short turn-around times and
moderate area-performance requirements.
