What is used to design the configuration of a field-programmable gate array (FPGA)?

Explanation

The logic inside an FPGA is described in a hardware description language such as VHDL or Verilog, which synthesis software compiles into the configuration data the device loads at power-up. Karnaugh maps are a hand method for minimising small logic expressions, auto-routers lay out circuit board copper, and machine or assembly language programs processors rather than gate arrays.
