This document contains VHDL code for multiplexer circuits and corrections for exercises on VHDL code. It includes:
1. Four ways to write VHDL code for a 2-to-1 multiplexer using different assignment methods.
2. Corrections for an exercise involving VHDL code for a circuit with 4 inputs and 2 outputs based on different input patterns.
3. The corrections provide 4 different ways to write the VHDL code using selective assignment, conditional assignment, if-then-else structure, and case-when structure.
4. VHDL code for a simple circuit with 2 inputs, 1 select line, and 1 output using an if-then process.

The document contains code for multiple VHDL programs. The first program defines an entity with ports for two 8-bit inputs, a 2-bit selector, and an 8-bit output. Based on the selector value, the output will be the sum, difference, AND, or OR of the two inputs. The second program defines a circuit with inputs A, B, a selector, a clock, and an output. It uses the inputs to compute two signals based on the selector, and outputs the selected signal on the clock edge. The third program defines an entity with 4 8-bit inputs, a selector, and a sum output. Based on the selector, it assigns the first two inputs to signals and adds them,

1. Syntaxe de Format
(Format destination control-string arguments)
• Destination : peut être t ou nil
•Si t : format donne le résultat à
l’écran et retourne nil
•Si nil : format ne sort pas de résultat
et renvoie ce qu’elle aurait du écrire
sous forme de chaîne de caractères
2. • Arguments : c’est une séquences de zéros ou
d’autres formes dont la valeur doit être écrite
• Control-string : c’est une chaîne de caractères
(~A) contenant la partie de la sortie + les
directives indiquant comment les arguments
doivent être écrits
• Il y a au moins 32 directives différentes ce qui
rend Format assez complexe
• Dans ce qui suit on donne quelques unes de
ces directives parmi les plus simples et les plus
utiles
3. • Il y a des directives qui n’appartiennent pas aux
arguments mais permettent de donner des
directions quant à l’apparence de la sortie
La dernière directive permet d’introduire une
control-string sur 2 ou plusieurs lignes
Directive output
~% # nouvelle ligne
~ & # nouvelle ligne sauf si déjà en début
d’une nouvelle ligne
~ ~ ~
~#newline Rien
4. Exemples
> (format t "~&Enter a sentence:")
Enter a sentence:
NIL
> (format nil "~&Enter a sentence:")
"Enter a sentence:"
> (format t "~&Enter a sentence~%:")
Enter a sentence
:
NIL
> (format t "~&Enter a sentence~~")
Enter a sentence~
NIL
5. > (format t "~&Enter a sentence
:")
Enter a sentence
:
NIL
> (format t "~&Enter a sentence~
:")
Enter a sentence:
NIL
6. • Les autres directives contrôlent l’impression
d’un argument et « consomme » un argument
Avec Format on peut évaluer
(format t "~&I heard you say ~A." sentence)
Directive Argument Comment argument est écrit
~ A Any object Without escape character
~S Any object With escape character
~{dir}~ A list Each member according to dir
Minuscule ou
majuscule
7. Directive Interprétation
