FPGAs, or Field Programmable Gate Arrays, are semiconductor devices comprised of reprogrammable logic blocks and interconnects, allowing them to be personalized to specific applications. FPGAs have become an increasingly important technology in embedded systems due to their flexibility, high speed and low power usage. In this article we will discuss the application field and working principle of the EP20K200FC484-3V FPGA from Altera.

The EP20K200FC484-3V is a low-power FPGA with around 20,000 logic elements and a 4Mb embedded SRAM. It is ideal for applications that require low-power and small form factor, such as wearables, internet-of-things (IoT) devices and connected embedded systems. The logic elements in the EP20K200FC484-3V are configured by a user-defined interconnect fabric which can be dynamically rearranged allowing users to quickly adapt their designs to changing requirements. The FPGA also includes low-power SERDES blocks, dedicated interfaces for communication protocols such as PCIe, Ethernet, and UART and an internal clock generator.

The EP20K200FC484-3V can be programmed using Altera’s proprietary Quartus Prime software suite. Quartus Prime allows users to configure the FPGA fabric and decide which logic elements are used and how they are connected. It also provides pre-verified libraries that can be used to build a variety of intellectual-property (IP) blocks such as multipliers and DSP functions. Additionally, Quartus Prime provides a powerful graphical waveform- and logic-editing environment for debugging user logic and for designing test bench waveforms.

The programming of the EP20K200FC484-3V can also be done using VHDL, Verilog or SystemVerilog. VHDL is a hardware description language which can be used to define the behavioral description of RTL designs. Verilog and SystemVerilog are HDLs which are used to describe the behavior, functionality and interconnect of digital blocks. Altera’s Quartus Prime supports all three of these languages and provides powerful synthesis capabilities to generate an optimal implementation of the design.

Once the design has been programmed, the FPGA fabric is implemented using several layers of metal interconnects. The metal interconnects are composed of a base level and several higher levels of metal interconnects, each of which provide shorter connections between components. The interconnects can, for example, bridge adjacent logic elements and connect distant components. The FPGA fabric is then connected to the input- and output-pins of the FPGA device and the device is ready for operation.

In addition to being used for embedded designs, the EP20K200FC484-3V can also be used for analog and mixed-signal applications. For these applications the FPGA fabric is configured to implement a complex analog- or mixed-signal design in a single integrated device. Examples of analog and mixed-signal applications that can be implemented on the EP20K200FC484-3V include motor control, signal conditioning and signal transmission.

The EP20K200FC484-3V is a versatile and powerful device which can be used in a wide range of embedded and mixed-signal applications. Its low-power and small form factor make it ideal for wearable and IoT devices, while its high speed and flexibility make it suitable for a variety of other applications.
