What is VHDL?
VHSIC Hardware Description Language (VHDL), where VHSIC is an acronym for Very High-Speed Integrated Circuits. It's an IEEE-standard HDL that was originally developed by the U.S. department of defence for documenting electronic systems. The language is specified in the IEEE 1076 standard and used to describe and simulate ICs and systems before fabrication. It is an alternative language to Verilog.

What is Verilog?
The Verilog HDL is an industry-accepted standard hardware description language commonly used to design ASICs and FPGAs. The designers of Verilog wanted to design a language based on the C programming language so that it would be familiar to engineers and readily accepted. In practice, it bears only a vague resemblance to C.

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.
