+# Digitaltechnik Labor
+
+Im Labor Digitaltechnik werden digitale Schaltungen entwickelt und getestet.
+In diesem Repository sind VHDL Dateien und die Setupdaten für die Simulation
+und die Schaltungssynthese für ein Altera DE1 FPGA Board.
+
+## UART Schnittstelle
+
+Das Ziel ist die Entwicklung einer UART Schnittstelle mit der Daten zwischen
+dem FPGA Board und einem Rechner ausgetauscht werden können. Auf dem Weg werden
+
+* Kombinatorische Schaltungen
+* Schieberegister
+* Zähler
+* Automaten
+
+vorgestellt. Aus diesen Komponenten wird dann die UART aufgebaut.
+
+## Entwurfsmethodik
+
+Die Schaltungen werden in der Hardwarebeschreibungssprache VHDL
+beschrieben.
+
+## Entwicklungswerkzeuge
+
+Für die Realiserung von Prototypen kommen programmierbare Logikbausteine in Form von FPGAs (engl. Field Programmable Gate Arrays) der Fa. Intel (früher: Altera) zum Einsatz. Die dazu notwendigen CAE-Werkzeuge sind im wesentlichen:
+
+* Editor: VSCodium
+* Simulation von VHDL-Modellen: GHDL/GtkWave
+* Synthese: Quartus (Fa. Intel)
+* Hardware: DE1 Prototypeboard (Fa. Terasic)
+
+## Messtechnik
+
+Für die Messung von zeitlichen Signalverläufen an dem FPGA gibt es Oszilloskope.
