FPGA programming is the process of planning and designing a software program that functions with specific hardware circuits. 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 the circuit that will generate a specific output when powered on.

Implementing an FPGA solution requires lots of planning to ensure that all features needed are included and will work correctly. A requirements document that includes all the specifications and details will help reduce the risk of problems in the process of implementation. It’s also recommended to create a simulation of the design at various stages of development using tools like Mentor Graphics Questa and Cadence Viva威而鋼
do along with Simulink.

Two programming languages have traditionally accounted for most of the work in FPGA programming, VHDL and Verilog. VHDL has a syntax that is similar to C, which makes it simpler to write programs. Verilog has a more V-like syntax and is deemed more user-friendly by some.

Typically, an FPGA design is implemented as a block of logic called a logic cell (LC) or a logic block (LB). It includes the standard logic functions like subtraction, multiplication, and addition, as well as some basic error checks for example, like the sign or negation of a numeric value. It also has lookup tables (LUTs) which store predefined lists of logic outputs for any combination of inputs.
