The Quartus software comes with a Vector Waveform Editor tool to allow users to draw the test input signals for simulation and select which signal should be shown in the simulation results. The method of running the Waveform Editor tool has varied over the various releases of the Quartus software. A brief discription of the Waveform Editor tool with regards to different versions of the Quartus software is given below. For more information, please see the FPGA University Program tutorial "Introduction to Quartus Simulation".
Starting with Quartus software v13.0, the Waveform Editor tool for performing simulations can be opened from within the Quartus software. This is accomplished by selecting “File -> New -> University Program VWF”. Test vectors created with this tool can be used in simulation of your circuits by running the ModelSim-Altera simulation tool. The simulator can be started from within the Waveform Editor, or by using the Altera Nativelink flow.
For Quartus software v10.1 through 12.1, the Waveform Editor tool could be used only to enter test inputs and set output signals to view. Running simulations was done using a separate tool, Qsim. For Quartus software v10.1 and 11.0, the QSim tool and Waveform Editor must be installed separately by using the FPGA University Program Installer. Beginning with the Quartus software v11.1, the QSim tool and Waveform Editor are bundled with the Quartus software. The QSim tool can be invoked from a command window by using the command "quartus_sh --qsim". The quartus_sh executable is part of the Quartus software. It can be found in the folder where the Quartus software is installed, for example C:\altera\12.0\quartus\bin. For this example of an installation folder you would type the command C:\altera\12.0\quartus\bin\quartus_sh --qsim. Note that if you are using the Quartus II Subscription Edition software and you are running a 64 bit operating system, then the executable is found in quartus\bin64\.
For Quartus software v9.1 and earlier, the Waveform Editor tool was included with the Quartus software and used the internal Quartus simulator.
