By FPGA programming is the method of preparing and designing the software program to work with a particular hardware circuit. It is a hardware-programmable technology that uses the combination of logic gates and memory blocks to undertake computing tasks. The main goal of the process is to create an electrical circuit that produces an output specific to the power source it is powered on.
The process of implementing an FPGA solution requires an extensive amount of planning to ensure that all the features necessary are present and working efficiently. A requirement document that contains all specifications and details can reduce the risk of issues during the process of implementation. It’s also a great idea to model the design using tools such as Mentor Graphics Questa, Cadence Vivado and Simulink at various stages of development.
Two programming languages have traditionally accounted for most of the work involved in FPGA programming, VHDL and Verilog. VHDL has a syntax that is get more similar to C, which makes it easier to write programs. Verilog is more V-like, and some find it easier to use.
Typically, FPGA designs are implemented as a block called a logic block, also known as a cell. It contains standard logic functions like subtraction, multiplication, and addition with some basic error checking for example, the negative and sign of a number. It also contains lookup tables (LUTs), which store predefined lists of logic outputs that can be utilized with any combination of inputs.
