• A designer can enter his /her design using a hardware description language (HDL).
• The HDLs prominent in the industry are “VHDL” and “Verilog”.
• There is another language that is recently making ground called as “System C”.
• Being similar to C language gives it an advantage to be more user friendly and comfortable to designers familiar with C.
• Using the code entry method is the most preferred one since it offers:
– Design flexibility.
– Code re-use.
– Easy modification.
– Tighter control over resources.
• A netlist is again created by compiling the HDL code.
