HDL code entry

• 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.
