FPGA FPGA BASICS What is FPGA Field Programmable
FPGA
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 Ø configuration pins Ø dedicated input or clock inputs Ø
USER PINS Ø Ø Ø 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
