Modern field-programmable gate arrays (FPGAs) contain hundreds of thousands of lookup tables (LUTs), hundreds of embedded memories, and hundreds of multipliers connected through a programmable interconnect fabric. Obviously it is intractable to program the FPGA at the granularity of these individual elements. However, with modern synthesis and layout tools, it is possible to describe a design simply by writing logical expressions, a level higher than gates, and letting the tools do the rest. Register transfer level (RTL) design is a ...
