Design library target FPGA synthesis

What is RTL?
RTL stands for Register Transfer Level. It is a high-level hardware description language (HDL) used for defining digital circuits. The most popular RTL languages are VHDL and Verilog.

What is FPGA?
Short for Field-Programmable Gate Array, a type of logic chip that can be programmed. An FPGA is similar to a PLD, but whereas PLDs are generally limited to hundreds of gates, FPGAs support thousands of gates. They are especially popular for prototyping integrated circuit designs. Once the design is set, hardwired chips are produced for faster performance.
