Question
What is used to design the configuration of a field-programmable gate array (FPGA)?
Answer Options
- A) Karnaugh maps
- B) Hardware description language (HDL)
- C) An auto-router
- D) Machine and assembly language
Correct Answer: B
Explanation
A Field-Programmable Gate Array (FPGA) is an integrated circuit that allows a digital designer to configure the internal logic blocks and interconnects to implement virtually any digital circuit. Unlike a microprocessor (which uses software or assembly language), an FPGA uses specialized programming to define the actual hardware structure.
The configuration of an FPGA is designed using a Hardware Description Language (HDL), such as VHDL or Verilog. HDL allows the designer to specify the logic functions, timing, and structural interconnections of the digital hardware. Specialized compiler tools then translate the HDL code into a configuration file that is loaded onto the FPGA to define its final, fixed digital circuit architecture.
