Abstract
In this chapter, we will show you how to use the basic elements (signals) to create combinational logic in VHDL (VHSIC (very high speed integrated circuit) Hardware Description Language). We’ll also cover two IEEE (Institute of Electrical and Electronics Engineers) libraries, namely, std_logic_1164 and numeric_std which provide features for more than just Boolean logic in your FPGA (field-programmable gateway array) design. By the end of this chapter you will know how to create a 4-bit adder using two different approaches and then you’ll use ModelSim to simulate the 4-bit adder.
