How do I export a waveform from ModelSim?

To save the current format of your Wave window, click in the Wave window so it becomes the active window, then choose File -> Save. The Save Format dialog box will appear. Browse to a directory that makes sense (i.e. your project directory) and save the . do file.

How do you get waveforms on ModelSim?

To display waveforms, select the design under test (inc) in the “sim” tab, right-click the mouse, and select “Add > To Wave >All items in region”. Alternately, bring up a wave window by selecting “View > Wave” in the ModelSim menu.

What is Vsim WLF File?

During a simulation run, ModelSim writes out a “vsim. wlf” file, which contains the waveform information for that run. To be able to view the saved results, load up the “vsim.wlf” file from within ModelSim as follows: Modelsim Prompt> vsim -view vsim.wlf. ModelSim will then load up the simulation information.

How do I get my transcript from ModelSim?

To display the Transcript window, click View ➤ Transcript. You can enter commands for ModelSim – Intel FPGA Edition directly in the Transcript window.

How do I open a .WLF file?

Depending on your operating system, you will right-click on the WLF file, select “Open With” and select either Argo WebLoad I Upload, Dr. Watson Win98/Me Log File, or a similar software program from the installed programs on your PC.

How do I run a VHDL code?

Create VHDL Source

1. Click New Source in the New Project Wizard to add to one new source to your project.
2. Type in the file name counter.
3. Select VHDL Module as the source type in the New Source Dialog box.
4. Verify that the Add to Project checkbox is selected.
5. Click Next.
6. Define the ports for your VHDL source.

How do I save a WLF file?

wlf file is overwritten with the new results. Therefore, you should use the -wlf argument to the vsim command to specify a different name if you want to save the WLF file. Important: You must end a simulation session with a quit or quit -sim command in order to produce a valid WLF file.

Why work is empty in ModelSim?

Else ModelSim might be simply compiling an empty file – which would, of course, yield nothing to add to a library. If that’s not the case, try this: Delete old work library. Use File > Change Directory to change to your working directory.

What is the difference between ModelSim and Questasim?

Questa is Mentor’s flagship product that has full System Verilog simulation support. Modelsim is an older product that has limited support for System Verilog. If you plan on using OVM/UVM then you would want to go with Questa, otherwise Modelsim is good enough.

How do I open an old project in ModelSim?

1 Answer. File=> Open, In the Open File dialog box, select Project Files (*. ini, *. mpf) in the Files of Type pull‐down, select the project and click Open.

How is the wave window used in ModelSim?

Now, the ModelSim GUI opens a number of windows and toolbars, as illustrated in Figure7, that are useful for performing a simulation. The Objects window, shown in a blue color, lists the input and output signals of the designed circuit. The Wave window is used to display waveforms that are associated with these inputs and outputs.

What can I do with the ModelSim simulator?

The ModelSim Simulator is a sophisticated and powerful tool that supports a variety of usage models.

What happens when you compile VHD in ModelSim?

As illustrated in the figure, the ModelSim GUI will indicate in the Transcript window (at the bottom) that the code in the majority.vhd file was successfully compiled, and a corresponding check mark will be displayed in the Status column. If you made any errors when typing the code, fix them accordingly and then compile again.

How to draw waveforms to simulate a circuit?

To simulate the circuit we must first specify the values of input signals, which can be done by drawing the input waveforms using the Wave window. Right-click in the Wave window to select Zoom Range and in the pop-up window that will appear specify the range from 0 to 800 ns.
