Quartus II

This page contains information about Quartus II, the fully IDE from Altera. You can find here tutorials, sample projects and information. It is intended for everyone who wants to learn more on digital design using Quartus II.

Most sample projects are based on the VHDL description language, but projects created with schematic diagrams will be added over time.

Beware that some of the documents are written in Dutch.

 

Tutorial Schematic Entry (updated, Dutch, 17-09-2018)
This tutorial covers the entry of a digital system using schematic entry such as logic gates. The use of sub design, creating hierarchy, is also covered. The creation of a project, connecting inputs and outputs to the device pins and simulation are not covered. When using this tutorial, additional settings are needed. These files can be found here.

Tutorial VHDL Entry (Dutch, 05-02-2018)
This tutorial covers the entry of a digital system using VHDL. The creation of a project, connecting inputs and outputs to the device pins and simulation are also covered. The tutorial includes a list of pin connections to switches, leds en seven segment displays.

Using Block Design Files with ModelSim (updated, English, 20-09-2018)
Schematic designs are saved in Block Design Files. Simulation using ModelSim is not directly possible, the design files have to be converted to VHDL or Verilog files. This set of files, including documentation, takes care of this problem.

Default Pin Assignments for DE0 Board
All pin assignments of the DE0 board can be found in the file default_pin_assignments_DE0.qsf. It's really a Tcl script that can be imported into Quartus. First, download the script and place it in the project directory. Then open the menu Assignments→Import Assignments. In the dialog that follows, select the file and press OK. The assigments will be read into the current project. Of course your project has to be open.

Tutorial State Machine Entry (Dutch, 29-04-2014)
This tutorial handles the entry of state machines with state diagrams in Quartus. In the first chapter, the editor is presented. The second chapter describes how a state machine is entered. The third chapter deals with the so-called Registered output & current/next clock cycle options. The state diagrams can be converted to VHDL or Verilog descriptions. Written by one of my students.

Installation of Quartus 13.0sp1/ModelSim 10.1d (Dutch, 6-8-2016)
These manuals will guide you through the installation process of Quartus 13.0sp1 and ModelSim 10.1d on Windows and Linux and include sections on how to install the USB-Blaster drivers on the subsequent OSes. Note that Quartus doesn't run on OS-X. Version 13.0sp1 is the last version that support both the Cyclone II (e.g. DE2-70 board) and Cyclone III (e.g. DE-0 board).

Ring counters (English)
This paper presents some insight in the construction and use of ring counters. LaTeX source provided.
