Simulations and prototyping have been a very important part of the electronics industry since a very long time now. Before heading in for the actual fabrication of a dedicated hardware, everyone would want to be sure that what they are making will work the way they want it to. Over all these years while electronics companies offered dedicated hardware in their products, it was not possible for the end user to reconfigure them to his own needs. This need led to the growth of a new market segment of customer configurable Field Programmable integrated circuits called Field Programmable Gate Arrays or FPGA.
