VHDL-What is it? VHSIC (Very High Speed Integrated Circuit) Hardware Description Language Not a programming language Know how code maps in hardware

Levels of Abstraction Digital system can be represented at different levels of abstraction Behavioral—relationship between input and output signals, usually boolean expressions Structural—description of the collection of gates and connections, more like a schematic Physical

Basic Structure of a VHDL File Entity Entity declaration: interface to outside world; defines input and output signals Architecture: describes the entity, contains processes, components operating concurrently

Entity Declaration entity NAME_OF_ENTITY is port (signal_names: mode type; signal_names: mode type; : signal_names: mode type); end [NAME_OF_ENTITY] ; NAME_OF_ENTITY: user defined signal_names: list of signals (both input and output) mode: in, out, buffer, inout type: boolean, integer, character, std_logic

Architecture Behavioral Model: architecture architecture_name of NAME_OF_ENTITY is -- Declarations ….. begin -- Statements end architecture_name;

Example-Buzzer System entity Buzzer is port (door, ignition, sbelt: in std_logic; warning: out std_logic); end Buzzer; architecture behavioral of Buzzer is begin Warning<= (not door and ignition) or (not sbelt and ignition); end behavioral;

Half Adder library ieee; use ieee.std_logic_1164.all; entity half_adder is port( x,y: in std_logic; sum, carry: out std_logic); end half_adder; architecture myadd of half_adder is begin sum <= x xor y; carry <= x and y; end myadd;

Processes Used in behavioral modeling that allows you to use sequential statements to describe the behavior of a system over time [process_label:] process [ (sensitivity_list) ] begin list of sequential statements such as: signal assignments variable assignments case statement exit statement if statement loop statement next statement null statement procedure call wait statement end process [process_label];

Full Adder HA1 S_ha = (A xor B) = int1 C_ha = (A and B) = int2 HA2 (A xor B) xor Cin = int1 xor Cin = Sum (A xor B) and Cin = int 1 and Cin = int3 int2 or int3 = Cout

Full Adder – using Processes library ieee; use ieee.std_logic_1164.all; entity FULL_ADDER is port (A, B, Cin : in std_logic; Sum, Cout : out std_logic); end FULL_ADDER; architecture BEHAV_FA of FULL_ADDER is signal int1, int2, int3: std_logic; begin -- Process P1 that defines the first half adder P1: process (A, B) begin int1<= A xor B; int2<= A and B; end process ; -- Process P2 that defines the second half adder and the OR -- gate P2: process (int1, int2, Cin) begin Sum <= int1 xor Cin; int3 <= int1 and Cin; Cout <= int2 or int3; end process; end BEHAV_FA;
