FPGA Design And Their Applications

 The contemporary world is surrounded by various technological advancements. The lives of humans are greatly dependent on the evolving technology in every field for living satisfactory and convenient lives. Electronic devices and semiconductor chips act a primary role in developing several technological devices for the consumers as well as for the industries.

There exist several varieties of semiconductor devices and chips, which are used in the various scenarios and applications. One such innovative semiconductor device is the FPGA, i.e. Field-programmable gate arrays, which are providing new ways for the industries to develop a wide spectrum of applications since decades.

FPGA Design

FPGA – Field Programmable Gate Array

 FPGA, also known as Field-Programmable Gate Array is a semiconductor device which is used to perform logical operations. These electronic devices are an integrated set of programmable logic blocks enclosed by I/O blocks which are embedded on a chip and their internal circuits are designed with the help of programmable logic gates. They contain separate configurable logic blocks that are interconnected to the programmable connection.

With the use of semiconductor technology in the FPGA construction process, these devices have the abilities to be programmed easily when exposed to the field as compared to other categories of semiconductor chips that are not very flexible in their designing and execution process.

The reason behind the wide use of FPGAs is that they can be easily reused and reprogrammed, and are highly flexible as it can easily adapt the personalization and customization of the designer when it is placed in the field.

That is why FPGA chips highly reliable and considerable in various applications as compared to ASICs chips, which can only execute one function at a time and the program loaded on the chip, cannot be either erased or modified.

 By using an FPGA chip, any program can be easily written by a person, which executes the functions after getting loaded on the silicon chip. Anyone can optimize his/her chips with the help of FPGA chips according to some workload. Aforementioned, An FPGA is a field-programmable device, so it delivers more flexibility and scalability.

These semiconductor devices can fulfill contemporary requirements of large complexity and great performance devices. Not only this, but they also deliver embedded processors, higher logic density, clocking and DSP blocks with their various prominent features.

Features in FPGA design:

Modern field-programmable gate arrays consist of a large number of RAM blocks and logic gates which are used to complicated digital computations. The design of FPGA has several bidirectional data buses and high speed I/O units, so it is difficult to verify accurate timing on proper data between setup and hold time. The feature of floor planning allows the allocation of resources within FPGAs to fulfill such time constraints.

These semiconductor devices are largely used to perform several logical functions which can be easily carried out by an ASIC as well. Certain FPGAs have analog features along with digital functions.

A typical analog feature is the programmable slew rate which is implemented on every output pin, which permits the designer to set the lightly loaded pins on low rates to prevent the unacceptable occurrence of coupling or ring, and set the heavily loaded pins on high rates when deployed on fast-moving channels, otherwise, it would work extremely slowly.

Various common features like RC oscillators, phase-locked loop implemented with voltage-controlled oscillators and quartz-crystal oscillators, which are implied in the management and clock generation for rapid serializer-deserializer to transmit clocks and its recovery clock time.

Various differential comparators are positioned at the input pins to connect differential signalling channels. FPGAs also have completely outlined analog-to-digital converters & vice-versa along with signal conditioning units which permit them to function as SOCs.

Different types of FPGA design:

The design architecture of the FPGA is widely responsible for its performance and density. FPGAs can be constructed into different designs depending on various parameters. Following is the list of different types of FPGA design:

On the basis of the internal alignment of logic blocks, FPGAs are divided into three types:

  • Symmetrical arrays
    In this type of arrangement, the logic blocks are aligned in the form of the matrix, consisting of rows and columns and other interconnect components arranged between them. The I/O blocks surround this symmetrical matrix which can be connected to the external devices.
  • Row-based architecture
    In this type of architecture, the rows of programmable interconnect tracks are alternated with the rows of the logic blocks and the I/O blocks are positioned at the edge of each row. A single row may form connections with the adjacent rows through vertical interconnect.
  • Hierarchical PLDs
    In this type of arrangement, FPGA architecture is constructed in a hierarchical manner in which the highest level contains only interconnects and logic blocks. Every logic block consists of numerous logic modules and every logic module contains sequential as well as combinational functional elements.

On the basis of the FPGAs programming technologies, they can be classified into three categories:

  • SRAM-based FPGAs
    These types of FPGAs contain Static RAM cells, which can control transmission gates, multiplexers or pass-transistor. These semiconductor devices are re-programmable with its upgraded designs, however, if the power is disconnected, the whole programming will be lost which requires to be configured when starting it. Hence, external memory is required by these devices to keep the program safe.
  • Antifuse-based FPGAs
    Such FPGAs utilize antifuse CMOS technology for programming them. Once an engineer completes programming the FPGA, then it is not possible to reprogram it. These devices can keep their program even if the power is switched off.
  • Flash-based FPGAs
    These kinds of FPGAs utilize floating gate cells in the form of switches to enhance area efficiency. Such FPGAs are not prone to lose information even when the power supply is disconnected. Moreover, they do not require external memory to keep the program; however, they are unable to reprogram themselves for an infinite number of times because charge gets buildup inside oxide.

On the basis of the application’s usage, FPGAs can be categorized into three types which are described below:

  • Low-End FPGAs: These types of FPGAs are the most suitable for those systems which require logic density, low complexity and low power consumption of the chip.
  • Mid-Range FPGAs: These kinds of FPGAs are regarded to provide the ideal solutions in many applications as it maintains a balance between density, consumption and complexity on a single chip within the cost range without needing to compromise in a large extend on either price or performance factor.
  • High-End FPGAs: These types of semiconductor devices are highly expensive and consume high power compared to their other types. But keeping these factors, these devices provide the best kind of functionality with maximum complexity and logic density, along with the best device performance.

Various applications of FPGAs:

FPGAs deliver manifold advantageous features which, when taken into consideration can be useful to develop varied types of applications. Since these semiconductor devices are commonly used for high complexity and low volume projects as they deliver higher customization power.
