FPGA programming is the method of designing and planning a software program that functions with the specific hardware circuit. It is a hardware-programmable technology that uses the combination of logic gates and memory blocks to undertake computing tasks. The goal is to build a system that will produce an output when powered on.
The process of implementing an FPGA solution involves many steps of planning to make sure that all features needed are present and working effectively. The creation of a requirements documentation that outlines all specifications and information can help in reducing potential issues during the implementation process. It’s also a great idea to test the design using tools such as Mentor Graphics Questa, Cadence Vivado and Simulink at different stages of development.
VHDL and Verilog are traditionally the two most popular programming languages for FPGA programming. VHDL has a syntax similar to C which makes it easier to write programs. Verilog has more of a V-like syntax and is deemed more user-friendly by a few.
Typically the FPGA design is implemented as a block of logic called a logic block (LC) or a logic block (LB). It has standard logic functions like subtraction, multiplication, addition and multiplication along with basic error-checking for example, the sign and negation of an integer. It also contains lookup tables (LUTs), which store the predefined lists of logic outputs that can be used with any combination of inputs.
