3.7 Drawing wires

Left click button to set into wire drawing mode. To draw a wire between two points If two points are not in line then Quartus II will include right angle junctions in the connection.

In normal symbol layout mode, it is possible to draw single wires. If you move the mouse cursor to a symbol terminal point, then the wire drawing cursor ( ) is activated. Draw line as normal.

A junction between two lines is shown by a dot. Create a wire junction by drawing the wire to the line. A junction will be created automatically.

3.9 Adding input/output points The input output points to circuits need to be marked for a number of reasons

1. input points for the injection of signals (for test)

2. output points to monitor results from the injection of test signals

3. to provide points which can be connected to real chip pins when the design is transferred to a physical FPGA device.

Input/output pins are placed on your drawing in the same way as logic components Example wired circuit with 3 inputs and 1 output.

A circuit with a wire missing Gives the following output in the lower information window

The concept of fault finding is central to many aspects of engineering. In general it is not easy, and requires the application of logical reasoning to the problem. Read the error messages carefully as these are the only pieces of evidence that you have to target the problem.

The designer can now select the signals to be displayed on a waveform diagram. The signal selection options are

1. Left click mouse to select a single signal. Erases all other selections 2. Left press mouse and drag to select a group of signals 3. Shift | left click mouse to select a signal while leaving all other selection unaffected.

5.4 Adjusting the view of the waveform The default conditions of the waveform are

• Time-scale increments shown as 10nS (10 nanoseconds). o This is likely to be too small as the physical delay of the chips used are in

the order 7 to 15 nS.. • Total waveform area has an end time of 1µS. (1 microsecond)

The view of the waveform can be changed in a number of ways 1.

The zoom tool ( ) can be used to zoom in and out of any part of the waveform. When activated

• C��

R to zoom out

• C��

L to zoom in

• C��

l to exit zoom mode.

2. The length of the simulation period can be modified by changing the end time. Use menu

item �� -�� ( to change.

3. To view the complete waveform to the end time, C��

R and choose menu item 0� �

�� . You can also use the keyboard :: � �� .

4. The mouse scroll wheel can be used to scroll quickly left and right.

5.5 Waveform timing bars The vertical timing bars allow designer to make timing measurements. When initially configured, waveform window has one timing bar called the � �� "�.

5.6 Editing input waveforms The designer must now configure appropriate input waveforms to check the operation of the circuit. To highlight a part of the waveform to edit The shaded are on the waveform can now be changed to a variety of values. The following table gives the most common options.

5.7 Running the Simulator Firstly, ensure that the circuit has been compiler. You must do this every time you change an aspect of your design. Refer to section 4 for details. Switch back to the simulator window if open, or select menu item -�� %�� -�. To run the simulator, it is necessary to generate a functional simulation netlist.

You can also use the start simulation button ( ) on the top button bar. If no errors are indicated, a window will give you the simulation results.

5.8 Printing Menu item File | Print… will give access to the Quartus II print facilities. All aspects of a project can be printed.

5.9 Grouping signals During simulation it is often very useful to group signals together and view them as single signal units. In our example circuit, we can group the three input signals as a unit. Return to waveform editor (section 5.1 )

6 Pin assignment In preparation for the generation of a file to be downloaded to the FPGA chip the input/output points of the circuit MUST be assigned to real pins on the chip.

Please check the documentation of the particular FPGA chip for the pin assignment information. This will vary for different FPGA development boards.

Select menu item 2 �� The assignments for an EPM7128SLC84-15 on the Heriot-Watt Digital Logic Trainer board is as follows

� CC��

L to list input/output points

� CC��

QUARTUS II GUIDE


The effect of these assignments is to add the I/O assignment information to the circuit diagram If you wish to change the assignments then re-select menu item 2 �� Please check the documentation of the particular FPGA chip for the pin

assignment information. This will vary for different FPGA development boards.

To change the Altera device being used in the project select menu item 2 �� &��( ��Remember that the pin structure of the new device may be significantly different and you may have to re-do all the pin assignments.
