What is an FPGA
An FPGA is configurable digital logic: the design becomes hardware structure after synthesis, place-and-route and bitstream generation.
An FPGA is a configurable logic device. You describe hardware behavior and structure in HDL, run synthesis, place-and-route, timing analysis, and then configure the chip with a bitstream. Treat clocking, reset, I/O standards and constraints as first-class design inputs.
