What are PLDs?
PLDs or programmable logic devices refer to a variety of logic chips that are programmable at the user's site. Programmability of logic means that new chip designs can be tested and easily changed without incurring the huge photomask costs for chips completed in a fab. In addition, memory-based PLDs can be reprogrammed over and over, which allows working products to be upgraded at the user's site.

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.
