Field Programmable Gate Array (FPGA) is a type of semiconductor device that can be programmed to perform specific functions. FPGAs consist of an array of programmable logic cells connected through a set of input/output (I/O) pins. The XC7VX485T-3FFG1157E is a FPGA from Xilinx. It has a Virtex-7 Series architecture, making it suitable for a high performance design.

Application Fields

XC7VX485T-3FFG1157E can be used in a variety of applications such as communications, industrial automation, automotive, medical, aerospace, networking and more. It can be used to implement any digital logic design more economically than custom designs. This FPGA has a high-speed transceiver, so it can be used to implement high-speed communication interfaces like HDMI, PCI Express, Ethernet, USB and more. It also has a floating-point unit, so it can be used to implement signal processing and machine learning applications.

Working Principle

FPGAs are field-programmable, meaning that the logic of the FPGA is programmed after it has been manufactured. This is done using the so called Hardware Description Language (HDL). A program written in HDL is called a design and it is used to program the FPGA’s logic cells, called logic blocks. The logic blocks are connected to each other through a network of switches called interconnects. In order to program the logic blocks and interconnects, the HDL-based design is written and then synthesised into HDL-defined net lists.

The synthesised HDL-based net list is then mapped onto the FPGA, a process of creating a physical net list using the physical components available in the FPGA, such as the logic blocks and interconnects. This process is called place and route. Once place and route is done, the FPGA can be programmed to perform the desired functionality.

Conclusion

XC7VX485T-3FFG1157E is a FPGA which is suitable for high performance designs. It can be used in a variety of applications because of its high-speed transceivers and floating point unit. It is field-programmable and the programming is done using the so called Hardware Description Language (HDL). The HDL-based design is then synthesised, mapped and programmed onto the FPGA to create the desired functionality.
