simple than other programmable devices

Elements of FPGA
The

basic elements of an Field Programmable Gate Array are:
Configurable logic blocks(CLBs)
Configurable input output blocks(IOBs)
Two layer metal network of vertical and horizontal lines for interconnecting the CLBS and FPGAs (programmable interconnect)

Architecture of FPGA
All FPGAs include a regular, programmable, and

flexible architecture of logic blocks surrounded by input/output blocks on the perimeter. These functional blocks are linked together by a hierarchy of highly versatile programmable interconnects.
