Using Questa on openlab

 

You will need to run an X-terminal on your computer to connect to Questa on openlab. Macs have it, as does Linux by default. For windows you would need

something like MobaXterm. Install it so that you can run the next command:

 

ssh -XY your-username @ openlab.ics.uci.edu

 

module load altera/questa/22.3

 

create (or cd to) your work directory where all your VHDL files are. 

 

Execute the following command at prompt

vsim

 

vsim will start Questa and open a GUI window on your computer. Use it to

·      Create a new project (or open an existing one)

·      Import your design files

·      Click on Compile and compile them - design before testbench

·      Click on Simulate and then Start Simulation. <br>

·      Enable Wave in View, add variables you want to track

 

Run simulation

 

Once in simulation, it is possible to set a signal to a desired value for debugging purposes. Select the signal you want to set in the waveform viewer, then click “Wave” at the top of the viewer, select “Freeze” and set the value in the little popup menu. The value will remain set to this value until another change is made.
