1. FPGA

2. 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

3. 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

4. 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

5. 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

6. 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
