1. Purpose of IEEE library in VHDL By Srujana Aramalla Instructor: Dr.Albert B. Grubbs

2. Design File It is an ASCII file containing VHDL source. A compiled design unit is stored in a design library. Each design library has a logical name with which it is referenced inside a VHDL description.

3. IEEE standards (Brief history) IEEE 1076 IEEE 1164 IEEE 1076.3 IEEE 1076.4

4. IEEE design library Contains the package STD_LOGIC_1164, which defines a nine-value logic type and its associated overloading functions and other utilities. Parts of the IEEE library can be included in an entity by inserting lines like these before entity declaration: library ieee; use ieee.std_logic_1164.all;
