The three major types of devices that is reigning the arena of digital
and electronic systems are memory, programmable logic and microprocessors.
Logic devices, both fixed and programmable ones take care of specific functions
that include interfacing, signal processing, data communication, data displays,
controlling operations and every basic function performed by a system.
Logic Devices: Fixed vs
Programmable
Programmable logic devices offer a host of advantages as compared to
their fixed counterparts. Programmable logic devices allow designers to make
use of cheap software tools in order to construct, simulate and quickly test
the designs before making them public. The design may be programmed quickly in
the device to test it on the live circuit. The PLD used for prototyping is
essentially the same PLD used in the manufacture of the concerned end
equipment, like a modem, network router or even a CD player. Apart from ensuring
quick completion of design, this process incurs nil NRE costs.
Important advantages of
PLDs
- Greater flexibility: PLD endows customers with greater flexibility during design cycle as design iterations require a simple change of the programs and the outcomes can be immediately visualized on the working parts.
- Quick prototyping: PLDs never require prolonged lead times to prototype production parts as they are always ready for transport. The quick prototyping is a feature of this process.
- Control over inventory: PLDs form a cost-effective solution in the sense that they allow consumers to order exact number of parts without the need to stock up for the future. This reduces wastage and unnecessary expenditure.
PLD training kit is an important and indispensable product to get
acquainted with the beneficial programmable logic devices and employ their
benefits for the requirements of the product manufacture to the fullest.
