Editing Place and route (section)

==Field-programmable gate array==
The process of placing and routing for an FPGA is generally not performed by a person, but uses a tool provided by the FPGA Vendor or  another software manufacturer.  The need for software tools is because of the complexity of the circuitry within the FPGA and the function the designer wishes to perform.  FPGA designs are described using logic diagrams containing [[digital logic]] and [[hardware description language|hardware description languages]] such as [[VHDL]] and [[Verilog]].  These will then be put through an automated place-and-route procedure to generate a pinout, which will be used to interface with the parts outside of the FPGA.<ref name="PCDandF" />
