FPGA Basics What is FPGA Field Programmable Gate Array An FPGA is a regular structure of logic cells (modules) and interconnect, which is under the designer’s complete control. An FPGA is really some programmable logic with a whole bunch of programmable wires

Advantage of Spartan family The relative positions of vcc and ground remain constant across like packages giving you the piece of mind that not to relay out. Our board when migrating to larger or smaller density devices

Tools of FPGA VHDL is used to describe digital designs. Inorder to build a chip several tools are needed Simulation tool Synthesis tool Implementation tool

Pin configuration of fpga Pins Vs pin dedicated FPGA pins fall into two categories 1. Dedicated pins 2. User pins DEDICATED PINS power pins configuration pins dedicated input or clock inputs

USER PINS The bulk of the pins an FPGA are user pins. I/O stands for input output. We have total control over user I/O. they can be programmed to be inputs, outputs, or bidirectional. Each I/O pin is connected to an I/O pins is connected to an I/O cell inside the FPGA. I/O bank An FPGA has many Vcc I/O pins, usually all connected to the same voltage. But new generation of FPGA’s have a concept of user I/O is split into groups, each have its own Vcc I/O voltage
